Amiibo Emulation

#10

You can emulate Amiibo with Proxmark3 easy but proxmark3 took different approach compared to flipper zero.

Flipper zero uses TRF7970A to implement NFC function but Proxmark3 easy uses FPGA to implement NFC. Thus, proxmark3 is much more flexible(software(?) defined NFC) compared to Flipper zero’s one(hardware backed NFC)

Direct Mode 0 "Raw RF Sub-CarrierData Stream on the TRF7970A can emulate an Amiibo, so it should be possible. There are also apps to do this on an Android phone

Looks like there’s a whole subreddit dedicated to Amiibo spoofing.

Most of the solutions on offer are to write the amiibo to a rfid tag that you supply. I want to straight up emulate the amiibo itself. No tag.

I would think so
You could probably upload them and download them from the internet to use with the Flipper

I’m having a little trouble locating the links, but there are complete Amiibo bin dumps floating around on the internet. I’m not sure how difficult it will be to take those files and emulate the NFC chip. There’s an android application which can write them to actual NFC “ntag215” cards, which may be of some interest in terms of seeing how it’s done: https://github.com/HiddenRamblings/TagMo

Here is a “v4” dump - not sure how up to date this is: https://drive.google.com/file/d/1-TWgQAH6v7R-odL5A0Rxu6wI_dWpkNMr/view

This works so well. I got NTAG215 stickers for dirt cheap. Easier then you think.

#17

Yeah, it’s quite easy to use the TagMo android app to write the actual NFC tags. I’m curious how difficult it would be to use the Flipper Zero to read and write these data files directly, eg can I keep a library of Amiibo files on the Flipper and write (and read) them directly to and from a Switch controller.

I just scanned an Amiibo with my flipper zero and it works fine. You can also emulate them and a Nintendo 3ds reads it just fine. So create your Amiibo list and save them all to the flipper :-).

#19

Did you scan the actual amiibo toy or from a tag? I scanned a tag (that I know works since it works on my Switch) but cannot get it to be read from Flipper to the Switch

#20

I read the Amiibo from a toy but I used the second read operation that let’s you pic from two options and I picked the bottom one on the flipper as using the normal read failed to emulate. But reading it this way emulated back to the Nintendo device just fine.

#21

If you hover the dpad on the flipper over the joystick, it read for me.

#22

Did you read from a 215 tag or the toy? So far no luck getting it to read from emulating the 215 tag

UPDATE: scanning in an nfc tag from a 215 sticker does work but the Flipper had to be hovered over the right joystick OR from the backside

#23

What did the saved file look like for the read from the toy?

#24

Here is my scan from the toy itself and it works fine with flipper emulating it. Just make sure you use Run Secial action and choose Read Mifareultra / Ntag to read the NFC tag.

Hah, I also wrote a python script yesterday to convert. I came here just now to post it and saw that others beat me too it.

Some other tips I discovered while working on this:

  • At least once my Flipper Zero got into a state where the emulation stopped working correctly. I appeared to be working (blinking light, etc) but a Nintendo Switch wouldn’t pick it up. A reboot of the Flipper Zero fixed it.
  • The file picker has limitations to how many files it will display in a directory. I needed to break up my thousand amiibo nfc files into directories. I was pleasantly surprised to find that the directory navigation worked well.
  • The sorting in the file picker in the current Flipper Zero firmware is a bit meh. There are tools such as “fatsort” (available in brew in MacOS) to sort files/directories within the FAT filesystem so they display nicely in the picker.
  • As far as I can tell, the hardware would be capable of programming a NTAG215 NFC tag so you can make your own amiibo coins and stickers but it doesn’t seem to be implemented in the firmware, yet. If I find time, I’ll work on it but I also suspect that someone here might already be and will beat me to it.

(Edit) Here is my python script, for completeness: https://gist.github.com/5c057f51cdc12f6d995051adb0531ddb

Once I have my full directories of bin files, what would I do to format everything so that it would be functional on the zero?
