It's not really a good/based on South Park, it's a Zelda hack actually.

If anyone finds a pirate/better hack than this please post, I wanna play South Park. ;D
Btw: I tried to play South Park Kart 64 on Project64 (whatever it's called) and it's buggy, i.e, tried 1-2 years ago but I think it's still the same.
The recent episode, is wow, I can't wait for part 2. :)
I dunno, this looks like a poor hack to me. There are many more interesting hacks out there, so why waste your time with this one?
