Sonic Unleashed Wii Iso Highly Compressed

This is where "highly compressed" gets real. CISO compresses the game using lossless (and sometimes lossy) algorithms. For Sonic Unleashed:

However, Level 9 compression requires the emulator (Dolphin) or USB Loader to decompress the data on-the-fly, which demands a powerful CPU. On a weak laptop, this causes severe lag.

Verdict: When you search for "highly compressed," you are likely looking for a CISO (Level 9) or a 7-Zip archive containing a stripped WBFS. However, Level 9 compression requires the emulator (Dolphin)

The raw ISO contains a lot of "dummy data" (empty sectors used to push game data to the faster outer edge of a physical disc). A standard compression tool like WinRAR or 7-Zip can strip this dummy data, reducing the file from 4.37 GB to roughly 1.2 GB.
