and all the description for it's compatibility is about PAL, so it's kinda hard to ignore...
I have not tried a 1:1 but I cant imagine it being much different. Wii Music NTSC-U on NTSC-U Wii run FLAWLESSLY decrypted.
Hope this helps you even a little.
I would test a 1:1 for you but I downloaded Wii Music the night it was first released (about two nights before 0.3 was released) and by default, had it patched. Once I saw that it worked, I trashed the ISO off my HD. Sorry.
