Nice site, you know I think I may have beaten the records you have for the 1st track. Sure I have been under 11 seconds and thought I might have done under a minute (this was about 5 years ago though so can't quite remember) but my snes is broken. I still have my Mario Kart cartridge so will have to see if any of my mates still have a working snes if they do I'll send you my stuff.

Generally you will need proof for any World Record set. Pictures most likely won't be accepted(too easy to edit). However, I know little of the SMK stuff, since I haven't played that game in a good 7 years.
