k, all virtual console game technically run off a virtual console(emulator). an injected wad is an virtual console emulator with a different game then the one it was made for. for instance, take the sin and punishment emulator and insert a super smash bros ROM in it. this is an injection. careful though, injected wads are dangerous, wouldnt risk if i were you. :)
Injected WADs are best left for stupid people and if you can't find a game you want just download it from rom site and use the appropriate emulator.
ok but i can't use the appropriate emulator if it isnt out yet, hence my question. but i know they recently made a new beta1 version of Wii64 and it seems to run pretty good now
