Portable Master System hardware
Sega's answer to the Game Boy had a backlit colour screen in 1990, years ahead of Nintendo โ at the cost of six AA batteries per six hours. Internally it is Master System hardware, so much of its library is shared.
Full-speed on all R36 models. The R36 screen is far larger than the original, so Game Gear titles look better here than they ever did on the hardware.
The chip is the same in every model, so the rating is too. What differs is the screen: 4:3 panels suit most home consoles, the 1:1 square panel suits Game Boy and GBA and shows 4:3 games with bars.
The R36 handheld family runs Game Gear titles with perfect compatibility out of the box.
