Is it 60hz only?
I realise I'm totally in the minority as most people are either too young to have grown up with it or they're old enough but have been angry about the PAL format since the 80s, but as someone who played the hell out of this game as a kid it'd be weird and slightly alien to hear all the music played at the true speed.
When all the angriness started I was hoping Nintendo might compromise by having a switch which would have been a great inclusion as I'd prefer most games that I grew up with in 50hz but games I didn't in 60hz, but oh well, 30p and all that, and theres always other ways to play the PAL original. It'll probably be nice to try it out as it was intended given that it's already there in Wii mode.
Good on them for listening either way.
