An older, block-based compressed ISO format. It is less efficient than RVZ but still widely recognized. Step-by-Step Guide to Compressing Dolphin Games dolphin games highly compressed work
If you’re serious about emulation, . Highly compressed formats like RVZ give you the exact same high-definition experience while letting you fit three times as many games on your device.
Physical GameCube and Wii discs were manufactured to a fixed storage capacity. If a game developer only used 500 MB of data to create a GameCube title, the remaining 900 MB of the disc was filled with randomized "dummy data" or garbage data. This padding was necessary for the physical disc drive lasers to read the data correctly. Do not trust 100MB downloads for games that are natively 4GB
As the gaming industry continues to evolve, it is likely that we will see new developments in the area of highly compressed work. Whether compressed games become a mainstream phenomenon or a niche interest remains to be seen. One thing is certain, however: Dolphin Games and highly compressed work will continue to play a significant role in the gaming industry for years to come.
ISO to WBFS comparisons are common, but RVZ often provides better results. For instance, while a WBFS file may be a certain size, an RVZ can be significantly smaller [12†L35-L36][12†L40-L41]. For the best balance of space and performance, many resources recommend using RVZ with advanced codecs like Zstandard (Zstd) [13†L19-L20]. It is less efficient than RVZ but still widely recognized

Dolphin’s own custom compression format, the , was the first major step toward shrinking your library. Using advanced zlib compression techniques, GCZ can reduce the size of a GameCube ISO by 50-70% . The best part? The compression is designed to be seamless; the game will look, sound, and play exactly as it would from an uncompressed ISO [11†L24-L25]. While GCZ is effective, it is largely considered a legacy format today, having been superseded by more advanced options.
A highly efficient format primarily used for Wii games, offering excellent space savings but slightly slower compression times.
