Compatibility with the Sega Mega Drive/Genesis
Despite what this article says Mega Drive / Genesis isn't compatible with Master System by hardware because MD / Gen lacks Zilog Z80 processor and the Power Base Converter adds this along with slot compatibility. It's no mere slot converter!

Current page contradicts with http://en.wikipedia.org/wiki/Sega_Mega_Drive#Master_System_compatibility —Preceding unsigned comment added by 88.240.60.43 (talk) 09:55, 25 April 2009 (UTC)
 * No, if you opened up a model 1 Genesis/Mega Drive, you'll find a Z80. Later models integrated the Z80 into the VDP. Please do your research next time. --67.164.13.222 (talk) 07:52, 26 July 2009 (UTC)

Minor Cleanup
We should change "The article Variations of the Sega Master System includes a more detailed view on these" into. Anyone with me? Jeremjay 24  ''' 14:15, 12 September 2009 (UTC)
 * Yes, that's true. --Jtalledo (talk) 18:40, 12 September 2009 (UTC)

Samsung Gam*Boy and Aladdin Boy
It would be nice to have information about the Korean versions of the SMS (Samsung Gam*Boy (삼성 겜보이) and the Samsung Aladdin Boy (삼성 알라딘보이)) in the article, along with a mention of the official Korean translation of Phantasy Star. Unfortunately, reliable sources are in short supply on these topics. Daram.G (talk) 01:47, 22 February 2010 (UTC)

Master System 3 image
Hello people, I have taken the time, the picture was so good to give a white background, which it thinks it can be integrated?

If you are satisfied, you are free to upload the image to Wikipedia and attached to the article. It can also revise further, if it is not good enough. :)Abani79 (talk) 09:57, 6 August 2010 (UTC)
 * Looks good. Maybe we can replace the current SMS 3 image with this one. I think it would be great if it had a transparent background. --Jtalledo (talk) 19:02, 7 August 2010 (UTC)

So I had reworked the image again on Monday and also airbrushed out the scratch with the Roman number 2, now looks much better, but the image is very large, perhaps you should reduce it, please upload it to the appropriate license, I am as experienced not so with. The size can also be left like that, you decide in its discretion. Abani79 (talk) 02:18, 11 August 2010 (UTC)
 * Great! If this is your final revision, I can upload it to the Commons. --Jtalledo (talk) 21:40, 11 August 2010 (UTC)

So now it looks very good, can be uploaded. :) Abani79 (talk) 08:14, 12 August 2010 (UTC)
 * Okay. I have uploaded the image as File:Sms3compacttransparent.png and replaced the old image in the article. Thanks again. --Jtalledo (talk) 11:16, 12 August 2010 (UTC)

MS compact image
Good evening, I have today the picture of the master system compact changed, it has now likewise transparent background. Hope all peoples like it, if it gives concerns, can i try to modify it again. Otherwise please replace it by the old picture. And thank you for your cooperation with me, so it's make fun to work as a "Wikipedian". :) - Thank you, Abani79 (talk) 18:51, 14 August 2010 (UTC)
 * OK. The image in the article has been replaced with the transparent background version. --Jtalledo (talk) 16:18, 15 August 2010 (UTC)

MS Girl image
Hello Jtalledo, thanks for the upload of the final ms compact image. Here are two edited versions of Master System Girl with white bg Master System Girl and the transparent version of the image, but traces of the dark background can be seen, what do you think? Sincerely Abani79 (talk) 17:57, 15 August 2010 (UTC)
 * They look alright - as thumbnails, it's hard to see the traces of the background anyway. --Jtalledo (talk) 19:30, 15 August 2010 (UTC)

I hope it has not become so bad. If you like, you can also ask them to upload yet? Arguably, this should have been first the last image. Thank you again. Abani79 (talk) 21:17, 15 August 2010 (UTC)
 * The version with the transparent background has been uploaded. --Jtalledo (talk) 12:14, 17 August 2010 (UTC)

Mark I/II or Mark III
this sentence doesn't make sense

"The SG-1000 and Mark III were available in Japan in the mid-1980s, and the successor to the Mark I/II, the Sega Mark III, was released in 1984."

I don't know enough to fix it but is tat first Mark III supposed to be Mark I/II? also I doesn't really enplane what the first two versions are. 140.232.184.192 (talk) 06:22, 30 January 2011 (UTC)

It is impossible that the Sega Master System sold 13 million Units
I have no idea how many units the SMS actually sold, but there is no way it could have reached the 13 million mark. This number can be traced back to a single source, even though it has proliferated since then, which is Eidolon's Inn, a Sega fan site that cites no sources for the figure, cannot be considered a reliable source since it is a fansite without professional editorial control, and exhibits shocking amounts of Sega bias (even for a fansite) in its so-called history sections. None of the other sources that have cited a 13 million figure have stated where they got the number from either, and no source from Sega, either through contemporary newspaper articles or company press releases, has ever provided a tally for the Master System. Unfortunately, this means the figures we have our incomplete, but what figures can be scrounged up show the impossibility readily enough.

First, Japan. Final figures are not known for Japan, but it is readily acknowledged by every reliable source that Nintendo destroyed Sega in the country. The book Game Over provides some of the best statistics for this dominance. On page 74, the book credits Nintendo with a 95% market share in Japan in 1989. On page 349, the book states that in 1988, Nintendo controlled 85 to 90 percent of the market "on both sides of the Pacific." We know from figures released by Nintendo such as those found at http://tctechcrunch2011.files.wordpress.com/2011/02/consolidated_sales_e1012.pdf (the original on Nintendo's website appears to be gone) that Nintendo sold over 19 million Famicom units in Japan over its life. This includes sales long after the Sega Master System was off the market, but to err on the side of caution we will assume that Sega sold ten percent of that figure, even though they probably could have only sold as much as five percent of a slightly smaller figure and probably less than that since this does not take into account sales of the PC Engine, which were stronger than Sega's sales. Rounding up, that gives 2 million in sales for Sega in Japan.

Next, the United States. In the Ultimate History of Video Games, Steven Kent states on page 360 that Sega had sold 100,000 systems by the end of 1987, the first full year the system had been on the market. An LA Times article at http://articles.latimes.com/1988-06-13/business/fi-3249_1_video-game-systems is more generous and pegs the number at half a million by the middle of 1988. A Minneapolis Star Tribune article from October 1991 excerpted on the search page at gives a figure of 1.5 million in the United States. Meanwhile, the book Game Over states on page 349 that Sega sold two million Master Systems in the United States. Lets use that figure and give Sega another two million.

Next up, Brazil. The Master System was popular in Brazil, as were Sega products in general, which were distributed by Tec Toy. Tec Toy was profiled in Issue 30 of Retrogamer and the president of the company stated that Tec Toy reached 2 million consoles sold in 1996. Many, maybe even most, of these are going to be Genesis sales, but lets be generous and call all of those Master System sales just for the heck of it. That's another two million for the Sega machine.

Finally, we travel to Europe, another region where Sega was popular and the Master System outperformed the NES. Finding figures for this region has been the most vexing of all for me, but I did find a forum post with a scan of an article in British game magazine from circa 1991 at http://www.atariage.com/forums/topic/166584-nes-vs-master-system-sales-rest-of-world/. This article reports that Sega's European distributor, Virgin Mastertronic, pegs total install base of Sega systems in Europe, both Master System and Genesis but probably mostly Master System at this point, at just over 1.6 million.

Adding up the above, we get roughly 7.6 million in sales. These figures leave out other parts of the world like Australia, but have almost certainly grossly exaggerated the sales in Japan and Brazil, so that hardly seems an issue. I do not claim to know what the final sales figures were, but all this data makes the six million figure that was briefly cited on this page awfully credible since my figures are both slightly incomplete and also probably exaggerated by around two million, but I would not revert back to that figure either since it also comes from the unreliable Eidolon's Inn (that's right, the website cannot decide itself whether the system sold 6 or 13 million units). Regardless, there is no way in heck that Sega sold 13 million systems. I'll leave this up for comment for a few days, but if no credible evidence for a larger figure can be found, I am getting rid of the sales figure on the grounds that no reliable source for Master System sales figures exists. Indrian (talk) 14:33, 21 September 2011 (UTC)
 * Not that it's exactly what you're looking for, but it will help with context: With regards to the US, this article discusses Sega sales and market share being in a distant third in the US. This source claims 2 million units sold. --Marty Goldberg (talk) 15:29, 21 September 2011 (UTC)
 * Any addition to the conversation is always useful. I have found several articles stating US market share in addition to the fine example presented above, which seems to fluctuate between five and 15 percent for Sega depending on the year and who is releasing figures (Sega always tends to claim higher than neutral trackers, unsurprisingly).  The consensus seems to be that Nintendo had about 70 percent of the market at the end of 1987 and gained from there until it hit somewhere between 85 and 90 percent by the end of the decade. Sega was generally in third behind Atari, as the above article notes.  The book source is parroting Sheff according to the in-line citation, whose 2 million figure from Game Over is already listed in my analysis. Indrian (talk) 16:11, 21 September 2011 (UTC)
 * Well, since my proposal has garnered little discussion and no objection in over 24 hours, I am going to go ahead and change this. If anyone can find some additional evidence, however, please do not hesitate to bring it here. Indrian (talk) 02:33, 23 September 2011 (UTC)
 * I don't know anything about the Master System, but I know this is supposed to be a reliable source. Take with that what you will.-- Sexy Kick  17:38, 27 November 2011 (UTC)
 * Well, two points in regard to that source. First, the 13 million figure was on wikipedia for years and became a de facto standard for this reason.  The original reporting of the 13 million figure appears to be Eidolon Inn, which is the only source that claimed to actually research the numbers (the creators do not say how they reached the figure, but at least claim they reached it with their own research rather than copying the figure from another source).  The number then appeared on wikipedia and travelled from there to several other articles on IGN and similar sites, none of which state how they arrived at the figure, meaning they were likley copying from either wikipedia or Eidolon Inn rather than conducting their own original research.  If you can find another site with the 13 million figure that predates Eidolon Inn and wikipedia, feel free to give it, but there are no known documents direct from Sega giving such a figure and no known estimates in newspaper articles or other sources from the 1980s or 1990s.  This number seems to appear out of thin air over the last few years with no sourcing whatsoever other than Eidolon Inn's vague claims of adding up totals from various mysterious sources.


 * Second, the site itself does not appear to have researched the matter too closely, as it breaks down the market between Nintendo and Sega when Atari had considerably more marketshare in the United States than Sega and the PC Engine had more marketshare in Japan (the article includes the PC Engine with the 16-bit systems, but its best years were in the late 1980s when it competed with the NES and during the transitional period between the Master System and the Mega Drive). This is a strong indication that the article is just parroting numbers on wikipedia, since the NES and false Master System figures are easy to find there and Atari's numbers require actual research to find (but believe me there are figures out there, as I have seen a few).  Furthermore, all sources agree that Nintendo had 85% to 95% of the market in the U.S. and Japan and the above Euorpean source indicates that Sega's European advantage would not shift those figures much on a worldwide basis since neither company sold many units there.  If Atari's and NEC's figures were added to those on that site, then Nintendo's marketshare of the 8-bit field would fall below 80% if the Master System really sold 13 million units, which is completely out of step with other reliable sources. Indrian (talk) 23:25, 27 November 2011 (UTC)


 * Very good studying Indrian. Good stuff. It's amazing how wikipedia gets used as sources. However, we should still write into the article the millions the console sold in which areas we have reliable sources for. If that's just 2 million in North America, that's good enough to put the Sega Master System on the best selling consoles list.-- Sexy Kick  00:43, 10 December 2011 (UTC)


 * While Indrian's research is very good, there's one flaw with it: it doesn't take into account that the Master System continued selling well into the mid-1990s, in both Europe and South America. If we look at the final sales figures for both the Atari 2600 and the NES, nearly half of their sales came long after their heyday (early 80s and late 80s, respectively). The same could well be true for the Master System. In other words, a worldwide figure of at least 10 million would be realistic for the Master System. With that said, it's hard to track down sources for a final worldwide figure, so there's no point continuing this debate any further for now. Jagged 85 (talk) 21:07, 16 January 2012 (UTC)


 * After doing some more research, I am now quite certain that the Master System did sell at least 13 million units. The 1995 issue of Screen Digest shows that the Master System's active installed user base in Western Europe peaked at 6.25 million as late as 1993. Since that figure is only for the active user base in that particular year, the actual sales for the console would in fact be higher, probably at least 7 or 8 million. If we also include the sales figures for North America, Brazil, and Japan, then 13 million is a very likely figure for the console's worldwide sales. Jagged 85 (talk) 06:36, 24 January 2012 (UTC)
 * Nice job pulling those numbers off of google books; that really does help paint a clearer picture. I remain skeptical of 13 million, but it was clearly much higher than six!.  Remeber, my Japan and Brazil figures above are deliberately overestimated to prove my point.  It is likely the console sold closer to one million in each territory.  You are correct that active install base forumulas generally include some provision for a rate of scrapping, so the number will be a little higher than the active install base, though I am not sure about eight million.  I see the total count as probably closer to 10-11 million, but I certainly admit 13 is not outside the realm of possibility and that the number is higher than I would have anticipated.  Thanks for the data. Indrian (talk) 15:44, 24 January 2012 (UTC)


 * I almost forgot about your Japan estimate. Your 2 million estimate sounds about right for Japan, since I assume most of the Mark III's sales there would have been before the arrival of the PC Engine in 1987. Nevertheless, I'm sure you'd agree that we should stick to the 1 million figure given in the source for its first-year sales. Jagged 85 (talk) 16:45, 24 January 2012 (UTC)
 * Absolutely, I think you misunderstood me. I never intended for that 2 million estimate to be an actual sales figure; it only existed to give a ceiling for Japanese sales as aprt of a larger analysis.  I never argued for its inclusion on the actual page.  Same with the Brazil figure. Indrian (talk) 16:55, 24 January 2012 (UTC)
 * I didn't mean it in that way. I already know you had no intention of ever including that 2 million upper-limit estimate, hence why I said I'm sure you'd agree with keeping it at 1 million. Jagged 85 (talk) 17:15, 24 January 2012 (UTC)

We can still write into the sales in the infobox North America: 2 million Europe: 6.25 million and have sources for both. It would be nice if we had a source for Japan, but we don't.-- Sexy Kick  07:36, 24 January 2012 (UTC)


 * Actually, after some searching around, I managed to find a source, a 1986 issue of Business Japan, which states the Sega Mark III sold 1 million units in Japan during its first year on sale. In Western Europe's case, 6.25 million is the active user base in 1993, but the actual sales were higher; I would put the Western Europe sales at least at 6.8 million, taking into account that the active user bases for Belgium and Italy peaked in 1991 and 1992 resepctively (all the other Western European countries peaked in 1993). Now that we have some sales figures for Japan (1 million in 1986), the US (2 million in 1992), Western Europe (at least 6.8 million in 1993), and Brazil (2 million for both Master System and Mega Drive in 1996), I would estimate the total sales at roughly 12 million (though the actual total sales would probably be closer to 13 million). Jagged 85 (talk) 15:54, 24 January 2012 (UTC)
 * I don't understand the 6.25 million source TBH. Do you think you could explain it a bit here?-- Sexy Kick  16:04, 24 January 2012 (UTC)
 * Also, as an editor you can't guestimate sales. But you can put "as of 1986" by Japan's date, and 6.25 million "as of 1995" after Europes.-- Sexy Kick  16:07, 24 January 2012 (UTC)
 * This looks pretty bad TBH. I can't make heads or tails of that Google books thing to make 6 million at all, much less 6.8 milliom, and you certainly shouldn't put brazil in the info box.-- Sexy Kick  16:15, 24 January 2012 (UTC)
 * 6.8 million is a guestimate based on differing peak install bases that I believe should not be used because it is slightly OR through synthesis and could be misleading based on other unknown factos in the numbers. I can see the 6.25 million though.  I assume the problem you are having is that snippet view in google books can be hard to follow.  Basically, Jagged is linking to the same piece of information three times via three searches that revealed the whole chart between them in the snippet view.  The first link shows that on page 60, there is a chart entitled Sega Consoles: Active install base.  Below that, you can barely make out that the list is divided into 8-bit and 16-bit figures.  The next link shows the same chart on page 60, and you can see the top half that shows install base for several European countries between 1991 and 1994 for both 8-bit (Master System) and 16-bit (Mega Drive) systems in hundreds of thousands (so you add three zeroes to any figure to get the full number).  The third link shows the rest of said chart including figures for all of Western Europe combined.  According to the chart, the combined Western Europe Sega 8-bit install base peaked in 1993 at 6,250 000s units, or to translate, 6,250,000.  Hope that helps. Indrian (talk) 16:33, 24 January 2012 (UTC)


 * Google Books only shows fragments of the page, which is why I posted multiple links (top, middle, and bottom) to get a fuller picture of the figures table. The bottom shows that the active installed user base in Western Europe was 6.25 million in 1993. However, the middle shows that, by 1993, the active user bases for Belgium and Italy had decreased by, respectively, 500,000 since 1991 and 50,000 units since 1992. If we add these figures to the 6.25 million, this would gave a total sales figure of 6.8 million units, though the actual sales figure would of course be higher. This is why I put the figure at 6.8 million. Jagged 85 (talk) 16:24, 24 January 2012 (UTC)


 * The 6.8 million estimate is derived from a single source, so I wouldn't consider it synthesis unless it was from several different sources. Yes, the source does not explicitly say 6.8 million, but that's the combined figure we would arrive at if we add up the peak active user base figures for all the countries (1991 for Belgium, 1992 for Italy, and 1993 for the rest). I think 6.8 million would be a reasonable figure to put down, as long as individual country figures are provided in the article itself. Jagged 85 (talk) 16:45, 24 January 2012 (UTC)
 * Okay, that's very helpful guys. I do think it's legit to add up the peak numbers. Doing the manual math, with this explanation, I do arrive at 6.8 million, and per WP:CALC this is not original research, so the source legit gives 6.8 million. I simply added 1991 Belgium, 1992 Italy, and 1993 for France, Germany, Netherlands, Spain, UK, and Other: 6.8 million. 1993 data translates to 'as of 1994' though. I'd say with the way things look now, you're able to edit the Sega Master System back into the list of best selling consoles with a footnote (copy the way the Mega Drive/Genesis is written).-- Sexy Kick  21:43, 24 January 2012 (UTC)


 * Thanks for settling it. Now that the figures for the US, Japan and Western Europe are settled, the only issue remaining is Brazil, which lacks an exact figure for the SMS but only gives a combined figure with the Mega Drive. My suggestion would be to give an estimate stating 9.8 million to 11.8 million (assuming Brazil sales could be anything from 0 to 2 million). Jagged 85 (talk) 01:48, 25 January 2012 (UTC)
 * Yeah, I suppose it really is not OR to go to 6.8 million, so I concede that point. The Brazilian stuff just does not work, however.  There are two million in sales divided among the Master System, Genesis, and Saturn (introduced in Brazil in 1995 according to the same Retrogamer article), so there is no way to tell what systems did what business unless some breakdowns can be discovered somewhere.  Furthermore, The Mega Drive was released just a year after the Master System, so  its likely that the 16-bit system greatly outsold the 8-bit system unless price and/or piracy became an issue in this developing world market.  In the approach suggested above, zero is clearly way too low and two million is way to high, so it gives an unrealistic range.  I would just leave that out of any sales number but explain in the body of the article that the Master System was one of several successful Sega products in Brazil that altogether achieved sales of two million units between September 1989 (which is when the Master System was released) and 1996.  That gives the reader the information without taking the sales number into wildly unverified territory.  Indrian (talk) 02:32, 25 January 2012 (UTC)


 * What I was suggesting was something more along the lines of the Sega Genesis article, where the infobox states "Estimated from 37.3 to over 40.9 million" with a footnote to break down the figures. Similarly, we could have something like that here stating "Estimated 9.8 to 11.8 million" or something along those lines. Jagged 85 (talk) 02:38, 25 January 2012 (UTC)
 * Well, that situation is a little different. In the Genesis case, all the numbers being referred to are specifically for sales of Genesis.  The problem is that two figures from different sources may have some overlap, but they also may not, hence the estimate.  Here we are talking about taking the sales of three different consoles in one region and assuming that all of those sales could have been Master System sales.  That's no good.  The Retrogamer article is a reliable source for Sega system sales from 1989 to 1996 in Brazil, but it is not a reliable source for Master System sales for the same period. Indrian (talk) 03:11, 25 January 2012 (UTC)

I have been in and out of this conversation, so forgive me if I'm off base here, but I thought that we have a ton of reliable sources for 13 million. That came into questions based on some research by Indrian, who suggested that one bad source was repeated by Wikipedia, which then became the source for the number in other articles. However, now that we know that there are at least 9.8 million in verified sales, the 13 million total seems completely realistic. Instead of conducting a bunch of OR to get to the WP:TRUTH, I think we should stick to the facts: RSs place the number at [13 million] (if that's the number). If you want, you can discuss that number with the research above (verified sales in x market of x amount and let the reader have the info. Just my two cents.LedRush (talk) 03:07, 25 January 2012 (UTC)
 * Eidolon Inn is not a reliable source. None of the game news website figures predate Eidolon Inn, so they are all suspect.  IGN and other such places are not sitting on secret proprietary sales figures from companies like Sega, which has never itself released this info, at least not in English.  They have the same level of knowledge that we do on this kind of ancient history that predates their operation as news reporters, so any source they used to come to the conclusion of 13 million, the public has access to as well.  Find an industry tracking group report/press release/SEC filing/interview with knowledgeable party that claims 13 million in sales and we have something to work with.  If you really think these places never use wikipedia as a shortcut for their research when looking at retro topics where the stakes are low and making a little mistake is not going to cause a publisher to impose sanctions on them, you are kidding yourself.  Ditto if you think IGN has the resources to research and verify every fact found in every article.  Therefore, parsing regions is the best we are going to get. As a final point, I am not trying to get to the truth in regards to actual sales figures.  I am trying to stop unreliable and clearly inaccurate figures from reaching wikipedia.  Ten million is closer to 13 million than I thought the Master System could have possibly reached, and I am elated to have this new information from Europe and a better overall picture of world sales.  It is not logical to conclude, however, that because ten can be reached that 13 must therefore be true. Indrian (talk) 03:11, 25 January 2012 (UTC)
 * That's my point. You say they are suspect, but this bit of research proves they are not.  WP does not find the TRUTH, it reports what RSs say.  IGN is a RS, no matter what your OR uncovers.  And no one is arguing that because 10 is proven 13 must be true, so put your torch down and back away from the straw man.  I'm saying that we have proven that 13 million is reasonable by the sources given.  I find the 6.8 million reading above to be a base minimum, one in which the actual sales numbers must be higher.  Others agree.  We know sales in Brazil weren't 0.  We know that there were sales in other regions.  Maybe 10.1 million is the right number, maybe 14 million is.  I don't know.  But it doesn't matter.  RSs say 13 million, and we no longer have a reasonable basis to ignore those RSs based on a quest for TRUTH which, by the manner of calculation, must use a number lower than actual sales.LedRush (talk) 03:32, 25 January 2012 (UTC)
 * A number that cannot be proven to have a basis in sound research is unreliable on its face, regardless of the source. There is no reason to trust IGN on this matter, because it has not attributed its information.  If we include the 13 million figure from IGN (likely, though not conclusively, picked up from wikipedia) then the encyclopedia is perpetuating something with a just as reasonable a chance of being wrong.  I have never understood why people argue that because wikipedia is not concerned with finding truth that it is also not concerned with errors. Wikipedia is concerned with information from reliable sources, but a source with bad information is inherently unreliable in regards to that particular information. Indrian (talk) 03:47, 25 January 2012 (UTC)


 * On a slightly unrelated note, you do realize that essentially none of the sales figures out there for games or consoles are actually correct, right? Only in rare cases does the actual creator of a product release its sales figures, as Nintendo did for all its consoles a few years back.  Most sales figures come from estimates either from tracking groups or analysts.  We could have reliable figures from reliable sources for every video game on wikipedia and those figures would probably still be inaccurate unless directly from the mouth of the publisher (and then you have to make sure they are actually talking about sell through rather than shipments to retailers, which they are usually not).  The truth is inherently unknowable, hence my lack of interest in it.  My interest is in limiting the sources of information on wikipedia to those that can be proven to have done their homework.  The amount of bad facts out in the world about video game history (provably bad, not sales figure estimates like we are discussing here) is truly shocking, and using substandard sourcing on wikipedia that will then get reflected back by other sources just makes it worse.  We, as editors of the site, have a duty to be more careful with the "knowledge" we throw around. Indrian (talk) 03:52, 25 January 2012 (UTC)
 * OK, we are talking past each other. I have clearly stated my opinion on why the RSs and the numbers reported therein are no "unrealiable on their face".  Your statement that you don't understand "why people argue that because wikipedia is not concerned with finding truth that it is also not concerned with errors."  I've never made that argument.  In fact, I think using a reasonable RS rather than a number we know is wrong is minimizing the risk of errors.  I simply believe that the OR you've conducted does more to prove the IGN number than to discredit it, and, all things being equal, it's better to use a RS than obviously and admittedly incomplete original research.LedRush (talk) 03:57, 25 January 2012 (UTC)
 * I believe I know exactly what you are saying (though please correct me if I am wrong). Your argument: 1. IGN is a reliable source. 2. IGN says 13 million.  3.No other reliable source has been found that explicitly disputes this figure. 4. An examination of other reliable sources in aggregate give no particular reason to dispute the figure.  5.  The IGN figure should be used.


 * Now my turn. 1. A source is only as reliable as the information it contains.  2. Even generally reliable sources have errors because we are all human. 3. IGN posits sales of 13 million without attribution of their sources.  4. IGN has never claimed to have proprietary information directly from Sega or from an array of tracking groups/analysts with knowledge of said sales and therefore researched this just like any other person would by looking at publicly available data. 5.On the Internet, the earliest know reference to 13 million and the only one to give attribution is Eidolon Inn, a fansite that claims to have researched the matter but does not name the sources used.  6.That number then spread to other places on the Internet, including wikipedia, and only later to IGN.  7.The Internet is not the whole of the world's knowledge, but so far no print sources have been provided to back up the claim either.  8.Therefore the farthest back this number can be traced is to Eidolon Inn.  9. Since no reliable sources have been found that have indicated a primary source from which this figure derives, there is a reasonable chance the source is the unreliable Eidolon Inn or, by proxy, wikipedia.  10.The information is therefore not reliable and has no place on wikipedia.


 * You say we are talking past each other. I disagree, at least for my part. Indrian (talk) 04:11, 25 January 2012 (UTC)

This is a tough matter indeed. No matter what the outcome, I certainly agree consensus is to not list Brazil in the other articles giving us 9.8 million for now. I suggest Indrian make a topic on Wikipedia_talk:WikiProject_Video_games and seek a consensus to either use the IGN source for 13 million (noting that it comes from WP/EI recirculation) or stick with the incomplete 9.8 million that we have. It's only three million short, and I'm sure we all agree that it's feasible Europe+the final four years of Japan sales can make it to 13 million. I don't know which side to take here...one thing is for sure to me ATM, ignoring 13 million completely, we have consensus to currently state an incomplete 9.8 million, right?-- Sexy Kick  04:31, 25 January 2012 (UTC)
 * I concur on all counts and will make the topic. My only correction would be that IGN getting the number from Eidolon Inn or wikipedia is not conclusive but only reasonably likely. Indrian (talk) 04:38, 25 January 2012 (UTC)
 * Indrian, thank you for making that point. I believe is is not even "reasonably likely" that IGN get the source from WP or Eidolon Inn based on the information we have here.
 * SexyKick, I do not agree with listing 9.8 million as a sales figure. However, I do agree with using the number in a manner like "sale in x, y, and z measured in years a, b and c equal at least 9.8 million according to ___".  But for the infobox, I would disagree with 9.8 million, or on any list of sales I would disagree with it.  For me the question is would we rather use a number that we know is wrong, or one that we think could potentially be wrong?LedRush (talk) 04:44, 25 January 2012 (UTC)
 * Hm, I'm confused. Do you agree, or disagree with the current infobox of this article? For the meantime, until we've worked the 13 million issue out, I'd prefer to use the guaranteed reliable data, note the years of each number, and make sure the SMS is included on the list of best selling consoles. The only way to to do it is to write in "9.8 million" with a footnote next to it that includes the regions data noting the "as of"'s.-- Sexy Kick  04:49, 25 January 2012 (UTC)
 * My first preference would be to use 13 million as we know the other information is not correct. My second preference would be to keep the infobox as it is, but putting the word "estimated" for the western europe number, as we are estimating sales based on active install base (pretty darn close to OR, and potentially OR, if you ask me). I don't think we should ever use the 9.8 million number as we know for a fact it is wrong and unsupported by any RS.LedRush (talk) 04:56, 25 January 2012 (UTC)

game gear section
Was the person writing this on drugs? The GG didn't take cards (didn't even have a slot for them), only cartridges, and I'm reasonably certain it had games over 256 kbyte (I'd have to go double check that) - certainly plenty over 256 kbit (the text doesn't make it clear which is meant by "kb"; given that it's discussing cards, it might be referring to their 32 kbyte (256 kbit) limit, which is minuscule for a GG game). Plus, it didn't have anything built in, as it was always sold with a pack-in game cartridge - usually Columns, the 4-in-one cart, or Sonic. There was far less to the carts themselves anyway, same as the difference between NES and Gameboy cartridges, so the difference in manufacturing cost would have been quite minimal.

Plus the MS didn't really "live on" in the GG... the MS continued to be sold alongside the GG for quite some time. It didn't die off anywhere near as quickly as the NES, as it was a somewhat more capable system and there was a smaller gap in the computing and audiovisual power between it and the Genesis/Megadrive - it became the budget choice, rather than the "old generation".

Finally there doesn't seem to be any mention of the two devices' architecture being so similar that you could get a cartridge converter for the GG to play MS cartridges on it - and it was little more than a connector bridge with no real onboard logic. The gamegear itself recognised that a mastersystem cartridge was connected and altered its internal rendering resolution to fit the graphics onscreen (cramming a 256x224 display into 160x140)... the main program code, colours, sound etc working unaltered.

I'll have a go at fixing this but it might be beyond salvage in its current form :-/ 193.63.174.211 (talk) 14:44, 11 February 2012 (UTC)
 * Take a stab, use sources, and make the project better. But please do not attack others who have tried to make this article as good as they can.

Cheers.LedRush (talk) 15:27, 11 February 2012 (UTC)


 * Sorry, I didn't get to come back and see this for more than a year, but I stand by my original statement. Anyone who's even seen a picture of a GG with a game cart inserted can see it doesn't use cards, and if you think Sonic can be crammed into 256kbit, well, good luck my friend. Moreover, a cursory glance at the GG article itself should disavow you of any such notions. Not a great deal of "trying to make it the best you can" when not even the simplest research that could be done in a couple of minutes whilst sat at the same computer has been done!


 * I'm going to quickly review the part in question, if it's still there, and fix it if needs be. I hope the wikipedia GG page is a good enough reference for the information, if a citation is even demanded, because I'm not going to go off trying to reinvent the wheel by finding independent references for well-known specs that are already listed and cited in the main article.


 * Let's put it this way: It's similar to someone claiming that the VW Beetle had three wheels, ran on steam, and doubled up as a helicopter if the traffic got too bad. OK, maybe they've done their best, but it's still plain wrong, and you don't need to know the machine's internals inside-out to point out the error. Having one drive past you on a busy street at rush-hour would answer at least two of those questions - three if you then crossed to the other side and looked back. 193.63.174.211 (talk) 13:43, 16 April 2013 (UTC)

Requested move
Master System → Sega Master System – Per WP:COMMONNAME. Unlike successor consoles such as the Dreamcast, Mega Drive (Genesis) and Saturn, Sega Master System is the common name. These other consoles are commonly referred to without the company name, but not the Sega Master System. This is why the dominant acronym is "SMS" not "MS". This is similar to "NES" for the Nintendo Entertainment System. Most other language wikis refer to it as "Sega Master System" including the Japanese one, as does Rovi and GameFAQs. --Jtalledo (talk) 14:26, 13 September 2012 (UTC)
 * Support per nom. Also "master system" doesn't show that this is different from a system of masters or mastership, from the searchbox. -- 76.65.131.248 (talk) —Preceding undated comment added 22:37, 13 September 2012 (UTC)
 * Oppose - That's not what WP:COMMONNAME is for, specifically it is for "common names that Wikipedia uses as article titles instead of more elaborate, formal, or scientific alternatives", which doesn't apply here. Both are common names, only the current one is less specific. If you read the rest of WP:Article titles the parts that apply here are:
 * Precision – Titles usually use names and terms that are precise enough to unambiguously define the topical scope of the article, but not overly precise.
 * Conciseness – Titles are concise, and not overly long.
 * This is expanded at WP:PRECISION. The Company+Product Name is overly-specific and overly-long, i.e. longer than it needs to be. This is the official name of the product, this is what was used in marketing materials and on the product itself, and this was what the system was known as while it was actually for sale. As far as the other comment about "system of masters", I'm not sure what that means, but that's what hatnote is for. Redirects cause the same conflation in the search box, so that's a non-issue. ▫  Johnny Mr Nin ja  21:29, 14 September 2012 (UTC)
 * Marketing materials and on the product itself? Look at the pictures of the console. There's a "Sega" before "Master System." Also see this box and this box if the logo bothers you. Again, the point is "Sega Master System" is the dominant name you see on websites, including other language Wikipedia sites. The "Sega" is not merely the company name, it is an integral part of the name just like the Nintendo in "Nintendo Entertainment System". Precision doesn't apply since you're adding a whopping four letters to "Master System." --Jtalledo (talk) 22:47, 14 September 2012 (UTC)


 * Support Title can be ambiguous, and also per the proof of the supporters. Hill Crest&#39;s WikiLaser! (BOOM!) 21:48, 17 September 2012 (UTC)
 * Oppose, as no other topics have the same name as this video game console. --George Ho (talk) 03:16, 28 September 2012 (UTC)
 * Having no other topics with the same name shouldn't be the sole criteria for naming. If that was the case, then Sega Genesis would be at Mega Drive. What does matter is if "Sega Master System" or "Master System" is the accurate title. I think it's the former. --Jtalledo (talk) 10:18, 28 September 2012 (UTC)

SegaScope 3-D
There were 7 not 8 games that supported the 3D Glasses. "Line of Fire" is listed by mistake in that section since it used an anaglyph mode (green/red glasses) instead of the shutter glasses. That's the reason the 3D Mode is just a "hidden feature" and there's no 3D in the title and no advertising like the big 3D Logo all the other games had. That's what the game looks like in 3D Mode: https://www.youtube.com/watch?v=2WqvAqUGOMs - shutter glasses won't work for sure. Unless someone has a proof that there was indeed a SegaScope Mode this should be removed from that list - and get an honourable mention somewhere in the text. --188.92.33.51 (talk) 08:58, 17 September 2012 (UTC)
 * Dunno. From what I've read, it does indeed support the 3D Glasses. However, it was not promoted as a 3D title since the default video mode is the non-3D mode. As for the YouTube video, I believe that was converted after the fact to red/green anaglyph format. --Jtalledo (talk) 13:25, 17 September 2012 (UTC)

Sprite count...
I have to wonder ... the "maximum 64 sprites" specification, is that natively, or with programming tricks? I've had my SMS back out of the cupboard recently, having finally got a replacement TV cable for it, and, well... the games haven't aged that well. And certainly, none of them look like they've got that many sprites going on at once, even when you count large ones being made up of multiple small ones. The game with the most stuff going on at once was Sonic (with the rings), but I'm not entirely convinced the rings aren't actually (minimally-)animated background tiles, as they don't move around relative to the backdrop and are usually on areas of flat "sky" (or "internal wall"/"jungle background") colour so the same single tileset could be used just with a different BG colour, rather than needing to use a sprite with one transparent colour.

Most of the games look like they get up to about 8 or so 16x8 (so maybe 16 8x8 ones) sprites on-screen at once before the system starts to have issues, and that seems a more realistic count. On replaying the old games I started noticing how sparse a lot of them now seemed, like Streets of Rage which never has more than three characters on screen at once (player plus two enemies or one large boss) plus a couple of additional items, or Sonic which rarely goes further than the blue bomber himself, one enemy, and maybe a power-up TV or moving platform. "Lemmings" pushes the boat out, with up to 20 walkers on screen at once (vs the bitmap systems it originated on, which allowed up to 100; the title screen actually mentions how it was "reprogrammed by Sega", and there's no 2-player mode despite there being two joyports and enough screen space to allow it), plus some simple background animation and decorations (again, nothing up to the level of the original, and the traps aren't animated -at all- ... surely there's enough ROM space for that?), and it suffers both flicker and slowdown when all of them are on screen together - and in this game in particular, they tend to end up all on about the same level as each other, and therefore share scanlines.

So, if the system (and the GG, too) can handle 64 simultaneous sprites, how come the games don't seem to bear this out? Is that including sprite assignments being re-used vertically, maybe? (If so, one assumes that it then becomes a problem of memory, and available VBlank/Hblank time to reprogram the VDP, as there is after room for 12 rows of 8x16 or 24 rows of 8x8 on a 192-line high screen, never mind a 224 or 240-line one... that would then equate to only 5, or even just 3 individual sprites on each scanline...)

Problem is, I know enough about these issues, and have played enough of the system to spot this seeming discrepancy, but I don't know enough about the programming or internals to actually fix it, if it needs fixing - or better explain it, which it almost certainly does. 193.63.174.211 (talk) 14:54, 16 April 2013 (UTC)
 * IIRC the MS is limited to 8 sprites on a single raster line. The 64 number is probably derived from how quickly the MS can reuse those 8 sprites across 240 raster lines. I.e. it takes 30 raster lines before you can reuse a sprite.


 * In that case it will be difficult to make a game that actually use all those 64 sprites at the same time, similar to how few games actually use 256 colors or the SNES as you bump into various limitations if you try.


 * Your observation on Sonic's rings is likely correct. A quick check on an emulator (Wakalabis) that lets me disable sprites does nothing to the rings. Anss123 (talk) 15:23, 16 April 2013 (UTC)

Master System III/3
I accidentally saved before I finished typing my edit summary, so I'll do that here: The "Master System 3" section mentioned the "Master System III" as if the reader already knew about it, when the article nowhere else mentions the III. So I've copied over the section on the III from the Variations article (which seems surprisingly lacking, in comparison, for a "main" article). —Frungi (talk) 06:04, 6 June 2013 (UTC)

Wikilinks to Sega Genesis
I have just reverted some changes to the wikilinks pointing to the Sega Genesis article. There seems to be an issue over the different names under which that system was released. The console was released as Sega Mega Drive in many parts of the world, however that page is currently a redirect to Sega Genesis, and wikilinks should point directly to it. I will also suggest that if there is disagreement over where the Genesis/Mega Drive article should reside, that discussion should take place over at Requested moves. Please see Moving a page for details. 66.18.219.221 (talk) 16:53, 19 January 2014 (UTC)

Behind the numbers
I'll provide more context for these references:
 * Just for the sake of readability, Screen Digest
 * Previous discussions came up with 9.8 million. All reported sales like these in Game Machines are rounded. For example, the 29 million Genesis figure (already rounded up from Famitsu's 28.58), is reported in this book as 30 million or Nintendo 64's 32.93 as 35 million. Its easier to discredit this book than everyone who claims 13 million. « Ryūkotsusei » 00:13, 18 March 2014 (UTC)
 * I've only just noticed this link. Most informative. THe units for the 8-bit systems are estimated base numbers per year, is there a total number for units sold to date somewhere in there?Halbared (talk) 15:40, 16 February 2021 (UTC)

Edit Request
The lead currently reads as such "The Master System could play both cartridges and the credit card-sized "Sega Cards," it should read "The Model 1 Master System could play both cartridges and the credit card-sized "Sega Cards," The Model 1 was the only model that could read "Sega Cards" and was the least sold unit with the SMS2 and the SMS3 being the most common and lacking that functionality. Also why is the page protected :S 62.252.234.102 (talk) 20:23, 2 April 2014 (UTC)

Edit Request 2. The built in titles were Sonic the Hedgehog and Alex Kidd in Miracle world, the "Snail Maze" game was only available on the Model 1 and was an Easter egg and could not be played without entering a code so it should not be listed. Also in the notable titles the Wonder Boy series of games should be listed as they were one of the most popular games on the system. 62.252.234.102 (talk) 20:35, 2 April 2014 (UTC)

Edit Request 3. The terms "Mega Drive" and "Genesis" are used interchangeably throughout the article, One term should be picked over the other and used through out the article. The first use of the term is in the lead "Retrospective reception to the system gives credit to the system's role in Sega's development of the Sega Genesis" Sega never developed the Sega Genesis, they developed the Sega Mega Drive and had to re brand it in North America due to a product by Supra called the "Megadrive ST" already existing. I think as such the term "Mega Drive" instead of "Genesis" should be used but either way one needs to be used through out instead of both. 62.252.234.102 (talk) 20:46, 2 April 2014 (UTC)
 * In response to your requests:
 * Certainly doable. I've uncovered this in my Retro Gamer source, so I can make that modification.
 * Snail Maze may have been an Easter egg, but reliable sources refer to it as a built-in game, so there's really not a reason to remove it since it's backed up. It's sort of a matter of how we consider it in that case, but sources consider it differently.  I can add a mention of Wonder Boy as one on the list without a problem.
 * That one is very selectively chosen for a reason, and I feel the need to elaborate here. The interchangeability is used only in reference to regional differences, with "Genesis" being the preferred non-regional term.  The reason for that is because of the long drawn-out debates at Talk:Sega Genesis that have resulted in that name being preferred, and any further discussion without new evidence being considered disruptive in that matter.  The statement of why it was rebranded is actually incorrect as well;  and I reviewed it during the GA review at Sega Genesis, and the truth is it's really not known for sure why Sega rebranded the console, as it appears the Supra detail may not be accurate.  Also, "Sega never developed the Sega Genesis"... really?  Then who did?
 * I'll also note as well that the page appears to have been semi-protected due to WP:SOCK abuse and was done recently. For those changes that I've responded to, I'll go ahead and make those for you.   Red Phoenix  let's talk... 00:54, 3 April 2014 (UTC)

Note
Here is some proposed text for the "Game library" section:
 * According to game designer Mark Cerny, most of Sega's early Master System titles were developed within a strict three-month deadline, and Sega's policies did not fully change until after the launch of the Genesis. Cerny has cited the 13-month development schedule allotted Sonic the Hedgehog, as well as the establishment of the Sega Technical Institute (an internal studio which acted outside of Sega's normal corporate structure), as representative of Sega's greater emphasis on quality control for its Genesis output.
 * 1.
 * 2.
 * 3.
 * 4.

I was about to add this material myself, but I just couldn't do it, as I personally believe Cerny's culture shock at Sega versus Atari does not amount to much more than a footnote in gaming history. That said, feel free to copy or modify this material if you disagree, as I'm hardly the arbiter of truth and my analysis could certainly be mistaken. The Guardian article makes clear that Cerny's critique extends to most of the Master System's library, even though he puts emphasis on 40 games that came out relatively early in the system's life, and that Cerny attributes the high quality and success of Sonic in part to its relatively lengthy development schedule.TheTimesAreAChanging (talk) 08:57, 6 June 2014 (UTC)
 * I've used at least the first sentence of this. It's noteworthy to the Master System's library to know about how long Sega allowed for development as that would affect the library and its quality, not unlike the library for the Sega 32X.  The second sentence I think is of questionable relevance to this article.

 * This article could use some help, which is not an uncommon thing with video game console articles. They tend to have fanboyism and overly emotional/controlling editors sitting on top of them. I suppose one could call this the kotaku influence. One symptom of this is the repetition of a single complaint or an aspect of praise many times within a short article. Another is distortions designed to flame or fan a product or competing product. Such symptoms are indicative of a religious fervor rather than an objective appraisal and subsequent focus on improving the article rather than sitting atop it like a monarch. Wikipedia in general suffers from the gleeful reversion syndrome, where editors revert without thinking enough to make the right decision (which is often not reversion) and "my pile of gold" syndrome — where editors think of certain articles as their property. — Preceding unsigned comment added by 174.233.14.20 (talk) 23:37, 5 November 2017 (UTC)

Light Phaser Origins
It's always been my understanding that the Light Phaser was not based on the guns in the anime Zillion, as stated in the article, but that the anime used the Light Phaser design. I can't check the source that's cited for this but I'm almost certain it's mistaken. 1) The anime came out months after the release of the Master System and the LP. 2) The anime was financed, at least in part, by Sega and 3) The character Opa Opa from Sega's Fantasy Zone series makes an appearance in the anime, well after the first Fantasy Zone game was released.

I'll try to find a source that I can cite to make the change. I found this article on Sega Retro that confirms the above, but it doesn't cite anything so I doubt it'll pass muster.

MHz "myth" in this article
The article is written in a manner that supports the MHz myth more than it challenges it. The first thing mentioned is the 4 MHz clock. It is then compared with the clock of the Nintendo. A caveat about architectural difference is tacked-on. But, when the first two of three references imply support for the MHz "myth" it means the article needs to have support for its implication. I reviewed a number of comparative appraisals of 8-bit processors and the results were mixed. The 6809 appears to be most commonly seen as the most advanced but its higher cost, among other factors, kept it from being widely adopted for things like video game consoles. Cost alone does not seem to be the only advantage of the 6502's design. One source said the low clock made it easier to implement lower-cost RAM and other hardware. Another source claimed the Z-80's long/slow memory address timing made it easy enough to implement low-cost memory. If someone can cite a truly definitive (truly comprehensive and authoritative) comparison to support the claim that the 4 MHz Z-80 (Z-80A, as I recall) in the Master System is quite superior to the CPU used in the Famicom/NES then that citation would be an improvement over the simplistic presentation of clock speed differences as being the primary factor. The clearly more primitive ColecoVision clearly shows that a higher-clocked Z-80A is not enough to make a system much more compelling than a Famicom. The idea that half a MHz more speed from a Z-80A would make the clock difference a dramatic improvement over the Famicom is dubious. Clearly, other aspects of the hardware, such as RAM sizes, are more important. The complexity of comparing the Genesis, also, with its faster CPU, versus the SNES, with its superior graphics and sound, also comes to mind in terms of this topic. — Preceding unsigned comment added by 174.233.14.20 (talk) 00:09, 6 November 2017 (UTC)

Possible deletion of 2 million sales claim in U.S.

 * For years wikipedia has had the Master System at 2 million sold despite most older sources saying 1.5 million. But I really can't see how the SMS sold 2 million units if it sold 1 million by 1990.


 * The Atari 7800 sold 1 million in 1988, 1988 would be Atari's best selling year for the 7800 and the 1 million was at June, so you had 6 months left in the year with two of those months being the busy holiday season. Some of this momentum would ride into 1989 by drop rapidly and the 7800 was selling at a low level for the rest of its life.


 * The Sega Master System sold 1 million by 1990. I am failing to find where that other 1 million would come from. The SMS was behind the 2600 and had no Peak that the 7800 had in 1988. Instead the SMS had a gradual increase, that would latter fall back down, due to the Genesis and arguably to a much lesser extent, the first year of the gamegear. But that boost for the SMS couldn't possibly have the SMS sell 1 million. It doesn't add up. SMS discontinued the SMS in NA because of low sales. So Sega selling around 1 million after 1990 then abruptly selling dozens of units doesn't make any sense.


 * If the SMS was basically non existent in sales in late 1991-1992, then the sales before that couldn't have been much better so Sega selling another million consoles is illogical. Heck, I'm finding it hard to believe they sold another 500k in NA but at least that's more believable and matches most older claims.


 * I say that we remove the 2 million number if no one can produce a reliable source that breaks down how 2 million is possible. Spike Danton (talk) 20:37, 24 August 2018 (UTC)
 * No objections to the removal of 2 million? Spike Danton (talk)  —Preceding undated comment added 14:14, 30 August 2018 (UTC)
 * I won't object to the removal of 2 million on one condition, and that's that the replacement figure has to be reliably cited. We had this issue for the longest time at Sega Genesis as well, so I'm not terribly surprised about this situation.  My caveat is that this is a featured article and thus supporting a new figure through a reliable source is a requirement for me.   Red Phoenix  talk  21:35, 30 August 2018 (UTC)
 * Has anyone managed to find a good source for he USA? The 13 million figure does seem too high combining Japan (1), Europe (7) and North America (even at 2).Halbared (talk) 10:56, 17 February 2021 (UTC)
 * Unfortunately I'm pretty sure this is going to be extremely difficult, if not impossible, to find. Sales figures in the video game industry are not published by the manufacturers and hard to find now. In the 1980s?  Nearly impossible.  That's why the estimate varies so much, between 10 and 13 million overall.  Throw in that North America had more than one distributor of the console and that may complicate matters even further.

Sales
Researchers have done some good job in trying to track down actual sales figures over estimates. UK is 1.5million and France is 995,000. This French site lists Master system sales by the year. https://www.mastersystem-france.com/t2217p15-le-resultat-de-la-guerre-presque-20-ans-apres There is year by year sales for the Master in the UK< here; https://www.neogaf.com/threads/retro-sales-age-thread.981407/page-2 Halbared (talk) 16:58, 4 November 2020 (UTC)

That's good sales data, though I'd be wary of Nintendo sales from a Sega publication. It does sort of conflict with data from EA here with the yearly UK sales. https://www.neogaf.com/threads/retro-sales-age-thread.981407/post-153404783. This is another post from that page with hard data from the UK mergers commission, though it's from 1991 onwards. https://www.neogaf.com/threads/retro-sales-age-thread.981407/post-153383705.Halbared (talk) 18:44, 17 February 2021 (UTC)
 * Of course I just realised, the European sales were the combined Master and Megadrive! :D . Halbared (talk) 18:46, 17 February 2021 (UTC)
 * Yeah, especially with Europe you have to watch for that. Uncommonly in Europe, Master System and Mega Drive sold at about the same time, and Master System was actually more popular at times.  The same goes for Brazil, but more so.  I have never seen anything like that with any other console.  Red Phoenix  talk  23:02, 17 February 2021 (UTC)
 * The sales for the 1990 year from the sales data from EA, which can viewed here; https://www.neogaf.com/threads/retro-sales-age-thread.981407/page-2#post-153404783, doesn't match with the sales data from the other source, I tried to look for the magazine, but could only see the cover. WHat are your thoughts, Red?Halbared (talk) 09:11, 20 May 2021 (UTC)
 * We need to see the actual source and we need to cite actual sources, not random web pictures or forums conducting original research. Especially when it comes to video game sales, there’s a high potential of bad WP:SYNTH because there are not official figures. Honestly, video game sales data is so hit-and-miss, especially in this period, that I’d be extremely wary without a concrete source that can be verified.  Red Phoenix  talk  10:43, 20 May 2021 (UTC)
