Sega NAOMI was a powerful arcade platform from 1998, based on Dreamcast hardware. It powered high-quality arcade games with impressive graphics for its era.
Same compatibility profile as Dreamcast, which shares the underlying hardware: simpler titles work, demanding ones slow down, on every R36 model.
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 Sega NAOMI titles with limited compatibility out of the box.
