I ran the rom in zsnes forced to 60hz (command line -t) and it detected the framerate and didn't play. Using the patch it got by that (my copier is 24 meg, otherwise I would have tested it.)
Basically: there's a japanese version of the game (ntsc,) and I doubt they did any changes to the pal version that had to do with timming. So applying that patch to the pal version will disable the pal check, and make it work on an unmodified ntsc system. Though if you were to play the cart or an unpatched rom, you'd need to switch to pal at the beginning of the game, then switch to ntsc to play it at 60hz.
