Apparently Majora's Mask would freeze on older Gamecube systems. Unfortunatley for me, my old GCn system doesnt work anymore, so thats where the Wii comes in for me on Gamecube titles, its actually nice to see Majora's Mask NOT freeze on me. But the game did run slower on Gamecube systems, but it was otherwise do-able.
What I do want to see is Donkey Kong 64, current said emulators on the PC supposedly dont work properly. It doesnt freeze, and yeah its the worst of Rare's DK games, but characters would clip through walls, cutscenes would not play properly crazy gravity depending on the environment or...just plain crazy. Plus since all nintendo ever does is tinker with the emulator, they cant edit the game itself.
