DiskCheck is a developer tool used to verify Wii disc images. This is done by testing the disc image for integrity, saving a CRC of the disc, then verifying it. Two versions are available, v1.00 and v1.01; v1.00 does not have a banner, v1.01 does. v1.00 was created before the retail Wii System Menu was distributed to third party developers and was intended to be launched using Nmenu.
