Maybe... I do not know...
But I am a tad doubtful of that though:
I know that Animal Crossing: City Folk KOR version uses IOS48, which appears to be nearly the same as IOS38, but with Korean Key support in it.
It may run under IOS48, but I think it may run under something like IOS55, seeing as it is a pretty new game...
Only one way to find out I guess...
BTW, does anybody know of a good website that accepts paypal and ships internationally where I could purchase Korean Wii games?
