Before converting your entire library, consider where you plan to play your games:
This is a raw rip of the GameCube disc. Even if the game is small (e.g., Animal Crossing ), an .iso will usually fill the entire capacity with "dummy" data. 2. Compressed Formats (.ciso, .wbfs)
If a developer created a game that only required 200 megabytes of actual data, they were forced to fill the remaining 1.15 GB of the disc with dummy data, often referred to as "garbage data" or "padding." This padding consists of meaningless strings of zeroes or random code intended solely to occupy physical space on the disc. When you rip a retail GameCube disc into a standard ISO format, that useless padding is preserved, bloating your storage. High-efficiency compression techniques target this redundant dummy data, stripping it away while leaving the essential game files completely untouched. The Evolution of GameCube Compression Formats
The audio crackled—a distorted cacophony of screams from Resident Evil 4 , the engine roar of F-Zero GX , the whimsical chimes of Super Mario Sunshine . They were all playing simultaneously, compressed into a single, chaotic frequency. gamecube games highly compressed hot
: This is currently the most popular ("hot") format. It allows for lossless compression, meaning you can reconstruct the original ISO byte-for-byte, while supporting modern algorithms like Zstandard (Zstd) .
: Significantly smaller when trimmed, as it primarily contains emulated N64 and NES ROMs. How to Compress
When you rip a GameCube disc into a standard ISO format, that dummy data is preserved, forcing every single game file to be exactly 1.35 GB. Modern compression tools are incredibly smart: they identify this useless padding and strip it away, leaving only the essential game data intact.

Early homebrew tools simply "trimmed" the dummy data from the end of the ISO file. While this worked for some games, it often broke others that expected data to be at specific sectors on the disc. This format is largely obsolete.
