Nintendo manufactured Wii games on standard single-layer or dual-layer DVDs. To ensure optimal disc reading speeds on physical console hardware, developers filled any unused space on the disc with random "garbage" or "dummy" data.
Not all compression formats are created equal. Depending on whether you are playing on the Dolphin Emulator or native Wii hardware, you will want to choose the right format. 1. RVZ (Best for Dolphin Emulator)
Historically the most popular format for playing games on actual Wii hardware via USB loaders. It strips out the padding, often reducing a 4.7 GB game like Wii Sports to just a few hundred megabytes. wii rom highly compressed

It was revolutionary in its time, allowing users to store games more efficiently on external hard drives.
