Key-Retail is, as best as I understand, the combined version of Locked-Secret and Unfixed-Info. There’s a similar file called Key-Retail that some of the newer amiibo technology uses. When combined, they activate a program that decrypts your amiibo – separately, they can’t do anything. These two files are the tools to decrypting the amiibo. What are the Locked-Secret and Unfixed-Info bin files? If you’re only wanting to emulate a few amiibo, then just buy the cards through online sellers. I estimate that in a given year tens of thousands of fanmade amiibo cards are sold through Etsy alone, and many more through eBay. Most people just use amiibo bin files to make amiibo cards, and often sell them online for a minor profit. Be loaded into emulators so the emulated game believes it’s had an amiibo scanned in.Load into Powersaves for Amiibo for use on a Powertag.Create NTAG215 chips and amiibo cards, which function identically to normal amiibo.How do I use amiibo bin files?Īmiibo bin files are used in a lot of different ways. On the console side of things, the Switch doesn’t know the difference – which is why you can’t get banned for using fake amiibo. The only difference between ROMs and amiibo in practice is that you’re not emulating an amiibo through software – you’re actually tricking the Switch with real, legitimate amiibo hardware into thinking that an amiibo has been scanned in. Reproduction cartridges are NTAG215 chips – they hold the bin file for use but can’t be rewritten (although the save data on the cartridge/NTAG chip can be).Flash cartridges are Powersaves for amiibo – they hold the bin file for use and can be rewritten.

Much in the same way that ROMs are used in emulators and flash cartridges, amiibo bin files are used to emulate amiibo. An amiibo bin file is basically the ROM image of an amiibo.
