OK thank you! A relief to know. Clashes a bit with the others, but if it's universal, then I can live with it.
Yeah Wii Fit Trainer freaked me out when i saw the difference. Though I got mine from a walmart so I knew it couldnt be anything but a North American release.
US have the name on the left side underneath the Smash Bros logo. EU/Australian have the name on the right side, top corner. Also has the release number (1-50 something). Japanese have Japanese writing (that's the easy one).
No region locking on these things so if you are in to opening them, it doesnt matter what version you have.
The exception so far is that ROB from japan is Famicom color theme. Where as US ROB is grey like the US Nintendo Entertainment System release. Also the three packs are singles in EU and Japan.
