Thenaya is a homebrew app which can program Amiibo dump files into blank NTAG215, making brand new Amiibos. It's the little sister of the TagMo project.

A better explanation of what this does:
The main thing this does is writing data from an Amiibo to a blank NFC tag, which is the thing inside an Amiibo that makes it work. (You can get packs of them online.) Got a backup of a golden Mario? Write it to a blank tag and boom, 3ds/WiiU/Switch will think the tag is a golden Mario. Forever. It'll function exactly the same as the real thing.

It can also dump (backup) an amiibo. This includes both what type of amiibo it is and game data, like Smash Bros fighter data. Want to use the same Amiibo on different games? Just keep a backup for each game and write it back to the Amiibo when you want to switch games.

The only thing it can't do is change an Amiibo/written tag from one type to another. That is a limitation of how these NFC tags work. You can't turn your golden Mario into a Peach. That would be weird.

Currently I consider it to be a Beta version. But it works fine for a number of people.

Usage is simple:
Copy the 3dsx/smdh files into 3ds folder.
Createa folder called "amiibo" in the sd root and put any amiibo dump files into it.
put the amiibo encryption key file to sd root with the name "amiibo_keys.bin"
Launch the app from homebrew launcher. Press X, select the file, press A, place blan NTAG215 tag on 3ds wait until finished.

Has been tested on both New3DS and Old3DS.

v0.7 (2 Aug 2017):
  • Fix for garbled text/progress.
v0.6 (8 Jul 2017):
  • Fixed: File picker stopped working if after browsing too many folders.
  • Added support for DPAD Left and Right to go into and out of folders.
  • Added suppot to Shoulder L/R buttons to page through the file list.
v0.5 (8 Jul 2017):
  • File browser can traverse directories
  • Restore tag function.

Credits extend to everyone who made TagMo possible. Specially to @javiMaD and Yellows8 who appears to have put in the NFC api into libctru.

So this essentially lets you copy and amiibo to a blank tag? Just looking for a more "layman" explanation.

Currently it is very much POC/Alpha stage. But it works for me (TM).

Copy the 3dsx/smdh files into 3ds folder.
Createa folder called "amiibo" in the sd root and put any amiibo dump files into it.
put the amiibo encryption key file to sd root with the name "amiibo_keys.bin"
Launch the app from homebrew launcher. Press X, select the file, press A, place blan NTAG215 tag on 3ds wait until finished.

I've only tested this on the New3DS, but hopefully it should work on the Old3DS as long as you have the NFC writer thingy for it.

Like i said it's mainly POC and needs time to get polished.

Looks like my dreams come true! Hope you will continue work on this and make a fully working, stable tool.. I have no access to nfc writers/android with nfc... so you are pretty much my last hope with that

Same error on N3DSXL "nfcInit() failed: 0xd0a17480" with B9S Luma3DS v8.0-e67c6ed3 sysnand, no emunand

Apperently that means INVALID_STATE not sure how nfcInit() can do that. I'm running 11.0.0.33 on 1st version of B9S and pre rosalina Luma. I'll update and see how it goes.

Just updated my 3ds to 11.4 (but still running old B9S and luma) and it worked. Could you try with legacy luma and the dump tag option (Y button) to see if basic NFC works?

--------------------- MERGED ---------------------------

This is great news. Are there any plans in the future to add save data reading/writing from existing Amiibo too?

Yes dump restore feature will be developed. Just wanted to get a POC out so I can see what works and what doesn't.

Oh yes, yes, YES! This is a godsend. All I need to do now is pick up an NFC adapter for my o3DS and I'm into the spoofing scene.

Please take user information experiences into account and make this work across all 3DS systems...
