Genesis:Region Locked Games

The following is a list of Genesis/Mega Drive games which will only play on a console of the same region, as they perform a check at boot to determine what region console they are running on. This check can be defeated by some region adapters, a Game Genie, or a region mod.

Much of the research behind this list comes from the region coding page on the Sega Retro wiki.

Japanese Releases

Note that most Japanese games will not physically fit in a Genesis or PAL Mega Drive, so the cartridge shape also acts as a form of regional lockout.
