Because I have the Japanese version of Mario Kart 64, and the MK64 sounds in Great Wario were in the English version, I decided to make this: A Japanese Wario soundpack. He also comes with an AIR file (for the intros to look normal), a DEF file (for the files) and a palette that resembles his MK64 appearance.
Could probably do this to other characters too, but Wario is a good start. I really don't know if somebody else did this, but who cares?
