Save disk space for ISOs

680 bytes added, 18:57, 5 July 2020
GameCube / Wii: added new rvz format
* Zelda Twilight Princess (GC): 1.4 GB (original) > 1.4 GB (GCZ) (game data already fills the disk)
* Megaman Collection (GC): 1.4 GB (original) > 1.1 GB (GCZ) (sound data is stored as uncompressed stream to fill disk)
 
===RVZ (Modern Dolphin format) - GC/Wii===
 
The Dolphin team developed a new compression format based on WIA called RVZ. Unlike all the previous formats, RVZ is lossless and can preserve the padding data on Wii discs as well as the necessary files needed by the Wii's IOS.
 
* '''Archive-quality dump?''' Yes.
* '''Gain:''' Immediate (ISO dump size lowers). Considerable, depending on the game.
* '''Tools Used:''' Dolphin 5.0-12188+ (right-click the game(s) in the games list and select "Compress ISO..." (or "Compressed selected ISOs..." if more than one is selected))
* '''Can be reverted?''' Yes.
* '''Playable on Hardware?''' No.
* '''Playable on Emulators?''' Only Dolphin.
