I have smash bros on the GC, but I don't use it on there anymore because of its low resolution on GC and Wii. I don't think I ever bought a game on the GC/Wii besides smash bros or even played a game besides smash bros on both consoles (resident evil 4 was a 5 minute exception and wii sports too).

With PS3 emulation its honestly easier to just buy the games used and rip them because of the enormous size of the PS3 games. I know. ;) Its unreasonable to download a 50GB game.
