Wii
Checks your Wii's original region
Run CheckRegion and it will tell you what region your Wii was originally, even if it has been region changed. If your Wii was purchased before May 2011 or does not have GC ports, the report should be 100% accurate. If that's not the case, there is a chance someone used Ohneschwanzenegger and a GC controller to create a new NAND, which allows a custom serial number, thus fooling CheckRegion. You can only then assume it's right if it reports a different region than your Wii's current one.
