Sega Mega Drive Flashback

The Sega Mega Drive Flashback, known as the Sega Genesis Flashback in North America, is an officially licensed Sega Mega Drive emulator console released by AtGames in 2017. It contains 85 emulated games from the Sega Master System, Sega Mega Drive and Game Gear, 9 of which are from the Sonic the Hedgehog series.

Hardware
The Flashback is an evolution over AtGames' previous products, most notably the Arcade Ultimate. It is a simplified Mega Drive system with 85 built-in games and two wireless controllers, but also a classic Mega Drive cartridge slot and controller ports. Unlike AtGames' previous systems, the Flashback only outputs through HDMI, rendering the image at 720p. A "rewind" function also exists to temporarily turn back time during play (up to six seconds), and the system supports ten save states per game, allowing games to be saved and loaded at any point. A scanline filter is also selectable to attempt to emulate a CRT display.
