I've been taking an interest in the differences between the game versions as well, and have already posted two videos which show version-dependant glitches:http://www.youtube.com/watch?v=EYMJ2g9ZG6whttp://www.youtube.com/watch?v=iV23LreFTeU
As I posted under the description for my "Over the Ice" glitch:
"To my knowledge, there are a total of three versions of the game: the American (3 revisions, plus the Competition Cartridge,) the European (2 revisions,) and the Japanese version (2 revisions.)"
That makes a total of eight different revisions for the SNES alone! Yikes!
There are a couple other version dependent glitches I could post about, but it'd probably be better if I created individual topics, huh?
