I was reading through this month's progress report and saw the bit about Wii disc MD5 checksum changing after scrubbing. Now a warning has been added so that users know this.
However, while the checksum of the image itself will change when removing the padding data, Wii discs have an internal checksum record that can be used to assess the integrity of the useful data, even after trimming the image. This is used by Wii Backup Manager and other tools to verify images compressed or not.
Does dolphin use this feature when verifying checksums?
I don't think the Gamecube discs have this feature, so compressing those does permanently prevent their integrity being verified after being compressed. Does anybody know?
