RetroN 3 (2010)
The was released in May 2010. It supports Nintendo Entertainment System (NES), Super NES (SNES) and Genesis games. It includes wireless controllers, as well as ports allowing for use of the original controllers released for each console. The RetroN 3 offers S-video or composite AV output. It retailed for $70, and came in two colors: red and black.

RetroN 3 HD, an updated version with HDMI output, was released on February 21, 2020.

RetroN 1 (2011)
The was released in January 2011, and only plays NES games.

A re-release, known as both the RetroN 1 HD and RetroN HD, came out in 2017. It has HDMI output and a controller that more closely resembles that of the NES. IGN believed that Hyperkin released the RetroN HD in response to Nintendo's discontinuation of the NES Classic Edition. The console received a mostly positive review from GameSpot.

RetroN 1 AV, an updated version with only composite video outputs, was released in early 2021.

RetroN 2 (2012)

The RetroN 5 received a mixed reception from critics. Huffington Post writer Michael Rundle gave the console a 4.5 out of 5 but wished it looked better and had the ability to play more consoles, such as the BBC Micro, Amiga, and Atari platforms. Brian Easton of BoingBoing said the quality is good although it "requires more force to remove [the cartridges] than feels comfortable".

The developers behind the RetroArch project claimed "the RetroN 5 violates several licenses". This was because the console used the Genesis Plus GX and SNES9x Next emulators to launch some games. Both of the emulators are filed under a non-commercial license, thus meaning they cannot be used in commercial products, such as the RetroN 5.

Hyperkin released the first RetroN 5 special edition called Hyper Beach a few years later.

The console was expected to launch during the 2017 holiday season. The RetroN 77 comes with four pack in homebrew games; Astronomer, Baby, Muncher 77 and Nexion 3D.
