The problem isn't so much the game itself, it's the hacked wii's with disc/hd loaders. There's apps you can run before you load the game itself which, well they basically function the same as a trainer for a PC game. So that's the main issue with it, and I think Nintendo have given up on trying to stop the whole homebrew thing.
