(7z, RAR, ZIP): Using LZMA, PPMd, or Brotli algorithms to compress the ISO. This can often shrink a 1.4 GB ISO down to 200–500 MB depending on the game. Textures and audio compress decently; video files do not.
As you can see, compressing a library of 50 games can easily free up dozens of gigabytes of storage, making it perfect for handheld emulators with limited MicroSD card space. How to Highly Compress Your Own GameCube ROMs
