SNES:Region Locked Games
NTSC and PAL SNES systems use a different lockout chip, which prevents games from one region being played on another. This can be bypassed by disabling the lockout chip in the console or using a "piggyback" cartridge adapter, but despite this, some games are capable of detecting what region console they are running on and will not run. The following is a list of games which check for the console's region, assuming the lockout chip has been bypassed. This can also be bypassed by adding a switch to select between 50 Hz and 60 Hz, or a SuperCIC mod board.
All games have been tested on both an NTSC SNES and a PAL SNES, using an SD2SNES with the SuperCIC function switched off.
NTSC Games on PAL Console
The following are NTSC games which will not work on a 50 Hz console. Note that US games use a different cartridge shape than PAL or Japanese games, which acts as another form of regional lockout.
