The 32X bolted two 32-bit SH-2 processors onto a Mega Drive in 1994 as a stopgap before the Saturn. It was abandoned within a year, but its short library includes a strong Doom port, Virtua Racing Deluxe and Knuckles Chaotix.
The 32X requires two SH-2 cores emulated alongside the Mega Drive itself, which is a real load for the RK3326 โ expect frame drops in the 3D titles, while 2D games such as Knuckles Chaotix fare better. The R36 Max and R36S Ultra use the same chip.
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 32X titles with limited compatibility out of the box.
