You have likely heard that downloading ROMs is illegal. The truth is nuanced:
Our stance: If you own a physical copy of the game, downloading a decrypted backup is ethically defensible. If you have never paid for the game, consider buying a used cartridge first to support the second-hand market, then download the ROM for convenience.
Let's be honest. The Internet Archive hosts these files, but downloading a decrypted ROM of Pokémon Ultra Sun if you do not own the cartridge is copyright infringement.
The preservation argument: Many 3DS games are no longer sold digitally. Physical copies are degrading. If you own a legal copy, creating a decrypted backup for use on a Steam Deck or PC is your fair use right in many jurisdictions.
The rule of thumb: Only download games you have physically purchased. Use the Internet Archive to replace a lost cart or to create an emulation copy of your existing library.
