The Ultimate Guide to Dolphin Highly Compressed Games: Save Space Without Losing Performance
If you're a fan of retro gaming, you know that building a library of GameCube and Wii titles can quickly devour your hard drive space. A single Wii game is typically 4.7GB, while GameCube discs take up 1.4GB [26]. However, much of that space is often just "garbage data"—filler added to fill the physical disc capacity [4].
By using highly compressed formats like RVZ, you can shrink these files significantly (sometimes down to 20MB for smaller titles like Animal Crossing) without sacrificing gameplay quality [4, 6]. The Best Way to Compress: Use RVZ
While older formats like GCZ, CISO, or NKit exist, the Dolphin development team officially recommends RVZ as the superior standard for high compression [5, 12, 14].
Why RVZ? It is a lossless format, meaning it preserves all original disc data while removing the unnecessary filler [6, 14].
Performance: Unlike other compressed formats that can cause stutters or crashes (like Super Paper Mario on NKit), RVZ is designed for real-time performance and has virtually no impact on gameplay if you have a multi-core CPU [7, 12].
Netplay Compatibility: Because it is lossless, RVZ discs are compatible with uncompressed ISOs for netplay and movie recordings [7]. How to Compress Your Games in Dolphin
You don’t need external software to compress your games; you can do it directly within the Dolphin Emulator: Open Dolphin and find your game in the list. Right-click on the game title. Select "Convert File" [5]. Choose RVZ as the format.
Compression Settings: The default settings (Zstandard with a compression level of 5) are generally best. You can increase the compression level for a smaller file size, but it will take longer to convert [13].
Click "Convert" and choose where to save your new, smaller file. Top Games for High Compression
Certain games see massive size reductions because they were originally much smaller than the discs they were printed on [4, 9]: Game Title Original Size Compressed Size (Approx.) Animal Crossing ~20MB Ported from N64; uses very little disc space [4]. The Legend of Zelda: Twilight Princess ~1.1GB Developed for GameCube; the Wii disc is mostly empty [9]. Super Mario Bros. Wii ~350MB Highly efficient assets and mostly 2D gameplay. Wii Sports ~600MB Contains very few high-res textures or videos. Pro Tips for Managing Your Library
