Japan-only release
Sega's first home console launched in Japan on the same day as the Famicom in 1983 and was comprehensively outsold. Its hardware became the basis for the Master System, so the two libraries are closely related.
Full-speed on all R36 models โ it is the least demanding Sega system supported.
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 SG-1000 titles with perfect compatibility out of the box.
