I've started a new project on google code called ooWii. So far it supports reading files from Wii/GC disc images, a sample is included for verifying your backups (binary is in the downloads section). Object Oriented Wii on googlecode ISO/CISO/WBFS files are supported as well as WBFS file system & burnt DVD's. WBFS file system support is largely untested ( I've only used a 2gb memory stick ), you need a drive letter allocated & it currently refuses to run if your free space map is incorrect ( talk to wimm about fixing that ). 4/04/2010: Uploaded veriify 0.2 which gives you a positive acknowledgement that your backup is ok.
