If you ran this emulator at it's current state on the "Earth Simulator" computer right now, you still wouldn't run at full speed. This emu is still WIP (if you don't know what that is, it's WORK IN PROGRESS). It's a proof of concept, showing that emulation of the GC is a possibility, nothing more than that. They are still working on it. Give them some time. Buy a GC, buy some games. If you want to see these games on your monitor, then either buy a VGA box or TV tuner card for your pc.
