Alex, a skilled programmer and gamer, had been searching for a reliable 7z to WBFS converter for months. He had tried various tools online, but none seemed to work flawlessly. Frustrated, he decided to take matters into his own hands.

This is a scrubbed game format. It removes the useless filler data from an ISO file, drastically reducing the file size (e.g., New Super Mario Bros. Wii shrinks from a 4.37 GB ISO down to a ~500 MB WBFS file). This is the standard format used by modern Wii USB loaders.

Leo didn’t believe it. He ejected the drive, plugged it into the Wii, and launched USB Loader GX.
