First, let’s address the technical elephant in the room. If you see a site offering a WBFS download for a Nintendo Switch game, it is likely a scam or a poorly labeled file.
WBFS (Wii Backup File System): This format was designed exclusively for the Nintendo Wii. It was used to compress Wii discs so they could fit on USB drives and SD cards.
