Hacking DIY amiibo cards

[Deleted User]

Well, you know that the Amiiwrite app is opensource - the amiibo read/write API is already wrote, you just need to make it save the BIN files and let us write them

Well for the Arduino it would probably be a bit more complicated than that. Assuming I don't use any sort of NFC chipset, I would have to do all the commands and timings myself. For example the WRITE command starts with the command 0xA2, the one byte value for the page address, the two byte CRC, and the 4 bytes of data that belong in that page. Then the NFC chip should respond with Acknowledge (ACK) or No Acknowledge (NAK).

Meh, if writing won't work on Android smartphone I need to buy an Arduino.

Who said that writing does not work on Android?

I think people seem to be having problems getting it working at the moment. But it must be possible if I can write an entire tag to an emulator.

Good news for Chinese bootleggers I guess.

No, we couldn't write it because there was no way to do so because AmiiWrite stores the BIN files inside a database inside /data/ which is only accessible to root users. We need someone to use the AmiiboWrite functions and design an app that takes BIN files.

Well if that's really all that's needed then I'll just fork it, change it to save in the SD card and package an apk up. I'll have to wait until I'm at home though.

Well, if root access is the only wall, that's not very hard...

Actually, this was not my stopping point, my phone is rooted, so I can copy the SQLlite DB to my PC, then add a few more rows to it. Not exactly sure if I will use Perl DBI or something, I have not done anything yet as I am still waiting for my tags. Then I would simply copy the DB back to the phone.

Wait a minute, are we even sure this app is going to do what we need? How do we know it will write the full contents of the memory and not just the amiibo stored data?

Guys... I am making 1 card *printable* for each amiibo following the same AR-Card format. Ill share when I am done .. I cant code or help with this project but nice amiibo printable ar-cards are always nice to have specially to stick those NFC Tags on the back.

--EDIT--

Here are 3 examples that I have completed so far (84 to go). Let me know what you think.

Spoiler: Examples

Ok, AmiiWrite isn't going to do what you need, but it is totally possible with android (I made an app to do it), so there is no reason to do anything super complicated (buying a nice PN533 NFC target for your computer isn't insane though). However, writing isn't going to help anybody as there is a piece of the encryption / signing process that we are missing. Until somebody reveals whatever part of the process we don't know, nobody will be able to get this to work.

Also, why is everybody getting confused by standard NFC UID stuff? This isn't a secret or anything, it is plainly explained in the spec.

Nice! These would go well with those card-form NFC tags linked a few pages back

I know right !! That is what I was thinking as well . I'm glad you liked them. Ill have them all read by end of today hopefully

Ya, I've been testing with some NTAG215 cards I got on amazon. I sort of want to get a card printer, but they are actually really expensive (like $800).

You can print them with a regular inkjet printer, but you need to buy a special tray.

@_Tim_ how close are we here, you braggadocious bastard

Ya, but it doesn't work as well as an actual card printer. I should be able to get some quality time with the one at work though XD

Hey I finished all 87 Amiibo cards (Covering every single amiibo release upto date excluding Animal Crossing cards) + an extra surprise for the REAL fans !! ( Spoiler below on the surprise )

Spoiler: Spoiler

It's KIPACHU !!!!!!!!
* For those who dont know kipachu http://9gag.com/gag/aDmmYV9/somebody-wanted-a-drawing-of-the-kipachu-here-you-go-d *

@_Tim_ OP If you would like to add this to the main post as an extra bonus I'm all for it. I put a lot of hours to get these ready. Hope everyone enjoys !!!!

I didn't know there was a file size limit on the attachments so I uploaded it to my OneDrive -25MB- : http://1drv.ms/1mSOlmS (Let me know if link goes bad)

Each Amiibo ARCARD has its own code. Kept the same codes to match the original ARCARDS and all other codes go in order in which they were released (As displayed by http://www.nintendo.com/amiibo/line-up Except for Yoshi.. which I skipped accidentally so he got first one )

Is there any chance you can share your app, just so we are ready when everything else is sorted?

Thanks for this, once I get my tags this will be really useful.
