Highly compressed. Impossibly small. A game cartridge holds megabytes of data; this file is the size of a sticky note. It defies logic, like trying to cram an ocean into a shot glass. You double-click.

The default ISO format is essentially a 1:1 digital photocopy of the original game disc. It contains every single bit of data, including empty "padding" data that the console’s slow optical drive needed to read efficiently. When playing from a solid-state drive (SSD) or a modern hard disk, that padding is just wasted space.

Emulation requires a ROM or disc image of the original game plus an emulator that mimics the console’s hardware. Dolphin runs GameCube and Wii games on PC and some mobile devices by translating console instructions and emulating peripherals. A “highly compressed” version generally uses lossless archive formats (e.g., ZIP, RAR, 7z) or split archives, often paired with converters that strip nonessential files, trim unused data, or apply compression settings to reduce size. Some distributions re-encode video/audio assets or remove language tracks to save space, while others rely solely on strong compression algorithms.

The safest way to get highly compressed games is to compress your own ISO files directly inside the Dolphin emulator. This guarantees your files will not contain malware.
