I 'd say you did a great job, thought looks like the format you went with for 60fps, probably didn't work so well. I do see some animation a bit off, and the process speed is too fast. I don't think this game was ever meant to go 60fps well at least like this. However at least you did try your best.
@NSRMario: Is that the pal version because the music is the correct speed, but the visual are not the correct speed, that happen when you play a pal version of the game into NTSC version n64?
and I thought I was hot shit just beating all 16 tracks in a row in 150cc. great job. also never knew about that funny sound when u delete ur save data, never tried that.
