There are a few unlicensed NES games (such as the Camerica games) that may not work without the lockout chip. Personally I just snipped pin 4 off and left it at that as there aren't any unlicensed games worth playing (well, Tengen Tetris but they work fine)

Won't your modified nes play all games once the lockout chip has been disabled? I have a famiclone which obviously doesn't have a lockout chip and it play all of my nes games just fine. Did I just get lucky?
