Yes, this one's already been done by someone else too (just like Paper Mario 2), but a huge problem with the rip was that
it cut out half of the Title song! And since the entire rip was a line-in recording, that meant race tracks were recorded and cut/paste in the pause menu. So I reripped the game, by converting all the available AST's, and recording the remaining 10 tracks in an attempt to achieve higher quality. Also has one or two unused tracks? (btw, track 33 kinda got nerfed in the recording process. oh well, it's only 2 seconds.)
