Iso Highly Compressed [best] — Call Of Duty Black Ops Wii

: If you own the original disc, you can use a homebrewed Wii and software like CleanRip to dump the game to an ISO file on a USB drive or SD card. Once dumped, you can compress it using tools like Wii Backup Manager (converts to WBFS format, which is smaller than ISO) or NKit (lossless compression).

The primary method for "compressing" Wii games isn't traditional file shrinking, but rather the removal of "garbage data."
