The King of Fighters 94 SNK NEOGEO NEO GEO MVS Cartridge, tested -f0218-2 Gameboy / Gameboy Advance Games PSU(Power supply unit/ AC Adapter):Very important notice The reading part of the cartridge has got rusted badly. I have cleaned up this part, but still is in bad condition. I had big trouble making the game wake up and it took about an hour until the game cartridge worked properly(Not exaggeration). Please keep in your mind that this cartridge is still in working condition, but you need some patience to play this cartridge.
