Wii | U Wua Roms Archive

| Aspect | Details | |--------|---------| | Copyright | Wii U games are copyrighted by Nintendo and other publishers. | | Distribution | Uploading or downloading full WUA archives is copyright infringement in most countries (US, EU, JP, etc.). | | Personal backups | Creating a WUA from your own legally purchased disc or digital copy may be legal under certain fair use / backup exemptions (e.g., US DMCA 1201 exemptions for abandoned online services – but Wii U online is mostly shut down). | | Risk | Downloading archives from unknown sources carries malware risk (e.g., fake .wua files that are actually ransomware). |

Note: The Cemu team does not endorse piracy. WUA is a technical format, not a license to distribute copyrighted games.
