Also sold as Mega-CD outside North America
The 1991 CD add-on for the Mega Drive brought CD audio, full-motion video and much larger games. It is remembered for both its FMV misfires and genuine highlights like Sonic CD, Lunar: The Silver Star and Snatcher.
Full-speed on all R36 models โ the CD hardware is still 16-bit. Requires the region-matching Sega CD BIOS, and games are large because of the CD audio and video.
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 CD titles with perfect compatibility out of the box.
