Using an adaptor like this, you can play the majority of imported games on you European (PAL) or Japanese (NTSCJ) Super Nintendo/Super Famicom.
Each game has a little chip inside, which tells the SNES where it’s from. This adaptor tricks (in this case) my European SNES to recognise an European games chip, while loading game-data from a North American or Japanese game.
