a game (or select multiple for batch processing). Select "Convert File" and choose RVZ as the format.
The pursuit of tiny files is understandable, but GameCube games are small enough that a $50 2TB external drive holds the entire library twice over. Don’t sacrifice quality or convenience for a few extra megabytes. Instead, compress wisely, play happily, and keep that purple cube’s legacy intact.
Handheld devices have precious limited storage. A compressed RVZ file plays just as smoothly as an ISO but takes up half the space. On an Android phone with a 128 GB SD card, compression is mandatory for a large library.
Downloading copyrighted GameCube ROMs from public websites is illegal in most jurisdictions if you do not own the original disc. However, creating your own compressed backups from discs you legally own is protected under fair use in many regions.
| Compression Level | Typical Size | Method | Speed | Accuracy | |------------------|--------------|--------|-------|----------| | None (ISO) | 1.46 GB | – | Instant | Perfect | | Standard (RVZ, CISO) | 300–600 MB | Lossless, removes padding | Fast | Perfect | | | 80 MB – 250 MB | Lossy or advanced LZMA2 | Slow to decompress | Variable |
There is a dark side to the search for highly compressed files. Some websites offer games compressed to unbelievably small sizes (e.g., 50 MB for Super Mario Sunshine ). These are often "repacks" or modified versions where the uploader has:
Dolphin will handle the "scrubbing" and compression automatically. Gamecube Rom Highly Compressed Portable
: Designed for maximum space-saving for archival, but sometimes requires conversion back to ISO before it will run properly on all emulators. Notable Size Reductions
You may have heard of —a format that used to be the gold standard for compression. NKIT could shrink Animal Crossing from 1.35 GB to just 64 MB by stripping padding. However, NKIT is no longer recommended because:
A standard GameCube disc holds 1.35 GB of data. While that seems tiny compared to modern 100 GB PS5 games, it adds up quickly. A collection of 50 GameCube games takes up nearly 70 GB of storage. For users with limited SSD space, older laptops, or handhelds, this is a problem.
