If you own a legal physical cartridge of Cassette Beasts (released physically by Limited Run Games or standard retail), you can use a homebrewed Switch with software like to dump your cartridge into an NSP file. This creates a backup ROM. You can then apply the official update NSPs and DLC NSPs (downloaded via Nintendo’s CDN if you own them) to create a "master install file."
