Unlike MP3s (lossy audio) or JPEGs (lossy images), high compression for Wii games is . Here is how it works:
with a matching checksum. It can often achieve compression ratios of up to 90% depending on the specific game. CISO (Compact ISO)
On the Dolphin emulator, RVZ files can sometimes load faster than uncompressed ISOs because your computer has to read fewer gigabytes off your hard drive. highly compressed wii games
A direct copy of the original disc. It includes "garbage data"—empty space filler used by the disc to maintain spinning speed.
To see the power of compression, look at how dramatically some popular Wii titles shrink when converted from raw ISOs to compressed WBFS files: Game Title Raw ISO Size Compressed WBFS Size Space Saved 92% The Legend of Zelda: Skyward Sword 10% Mario Kart Wii 40% Wii Sports 92% Punch-Out!! 15% Super Mario Galaxy 2 70% Unlike MP3s (lossy audio) or JPEGs (lossy images),
Developed specifically by the creators of the Dolphin emulator. RVZ is a highly advanced, lossless format that compresses game data and padding seamlessly, making it the absolute best choice for PC and mobile emulation. Top Highly Compressed Wii Games Examples

On paper, it was impossible. A single Wii disc held 4.7GB. The math didn't add up—unless you stopped treating data like code and started treating it like DNA. "Open it," whispered Jax, leaning over Kael’s shoulder.
A tiny puzzle game that only contains 200 MB of real game code still generates a 4.37 GB ISO file.
You don't need to download risky, pre-compressed files. You can turn your own ISO files into highly compressed versions using freely available tools. 1. Using WIT (Wiimms ISO Tools)
In the context of the Wii library, a "highly compressed" game is not a rip that has removed cutscenes or audio (often called "RIPs" to keep file sizes small). Instead, it refers to compressed disc images that utilize specific archival formats (like WBFS, WIA, or RVZ) to store the game data without the 4.37 GB of padding found on standard retail discs.
