Folder Structure is Critical:
USB Loaders require a specific naming convention. Wii Backup Fusion usually handles this automatically, but the manual structure is:

wbfs/
├── Game Name [GameID]/
│   ├── GameID.wbfs
│   └── GameID.wbf1 (if split)

Example: wbfs/New Super Mario Bros. Wii [SMNE01]/SMNE01.wbfs

The Game ID is crucial (e.g., SMNE01 for NTSC Mario, SPMP01 for PAL Mario). You can look up Game IDs on GametDB.

    When you rip a Wii game disc, the raw data creates a massive file (usually around 4.7 GB). However, Wii game discs are filled with "junk data" (padding) to fill the disc space. The actual game data is often much smaller.

    A WBFS file is a "scrubbed" version of the game. It strips out that useless padding data.

    Most users download WBFS files or convert their own ISO backups. Here is the modern, safest method.
