How do you use gameshark codes on the PC?
No, absolutely not. The PC is completely different to the Gamecube, as is every other consoles. If it were the case that they were similar, then you’d be able to play a PC game on, say, a PS2. I think your bast bet here is to find out a site that hosts PC game saves (I don’t know one off-hand, sorry), and download one from there with all the features unlocked that you want. But, I beg you to ignore the previous user’s question – I don’t think he’s read your question correctly; I think he’s thinking you’ve emulated the GC game on the PC – which is a whole different ball game.
