I reckon developers could indeed help try to stop piracy by making games not work right if certain titles are present in wii (Say perhaps, HAXX, i.e. HBC?), but looking at PSP, games which stop working on CFW are the ones pirated the most because ISOs can have the protection patched out of them. And also, Nintendo don't seem too opposed to Homebrew, which I can understand, but surely they should be opposed to piracy?
