Hacking DIY amiibo cards

[izy]

An Ntag 216 could be used insted of Ntag 215?
The tag 216 has more memory so the amiibo dump should fit without problems, and it's more cheap than the 215.
The extra bytes could be leaved as blank. I don't know if the console will say "corrupted data" or something if theres more data than expected. There are only asumptions.

maybe it requires the exact bytes no excess, like how the sky3ds works to act like a legit card.

Either way NFC215 tag is exactly 540 bytes, every dump i have seen from that site *looking at the archive now* they all all exactly 540bytes.

atm 215 tags are cheaper than 216 tags or cost the same when the deal is over on aliexpress

Yeah, my bad. The price is cheap on the 215 but buy a stack of 100 units it's a bit... excessive. If there was a little stacks could be cool.
For that i was asking about the 216 beacause you can find stacks of 6 units in a reasonable price.

The only gap is the encryption. Right now, it isn't possible to encrypt the dump unless you somehow track down the Amiibo crypto key (which I haven't seen anywhere), or you get an API for amiitool (which isn't a great solution as you are then dependent on that API). Ideally, we would have a way the key (with some thinly veiled distribution method like an illegal prime or key generator ALA MakeKeyBin), in which case it would be pretty easy to build an Android app that would let you just use any NTAG215 as an Amiibo.

yeah it's basically a useless idea right now

- compatible software to write an amiibo dump to a blank NTAG215 tag (I could not find any so wrote my own)

Well, that's what stop me to try your method :x, why not upload your soft ?

So you can encrypt and decryt amiibos but don't have a sofwtware to write the data to the nfc tags?

Well i saw there is tools to decrypt/enc, didn't made a full search atm, but still, this is the only steps the OP don't know and i don't know either so x).

 

[Supercool330]

There are tools to encrypt and decrypt, but the key to do so isn't publicly available.

Wouldn't it technically be possible to hack the amiiqo Android app to accept any tag since that's what it does except it accepts only amiiqo?

Still need to figure out how to encrypt though.

No.

No.

Do all the Blank tags have the Same UID? was thinking cause they a batch,

No.

 

[zezzo]

No.


No.


No.

COULD YOU EXPLAIN IT?

COULD YOU EXPLAIN IT?

DEFINE "IT"

 

[piratesephiroth]

DEFINE "IT"

So you use that amiibo decryption service to encrypt your files?

No, I used a modified version of amiitool to decrypt/encrypt the amiibo data.

 

[piratesephiroth]

No, I used a modified version of amiitool to decrypt/encrypt the amiibo data.

I see. So you have the keys.

 

[OctopusRift]

Ah, I see that you found the keys too, congrats

Thanks m8! Now I just need to figure out how to write to a 203 tag lmao... which is the only NFC tag I have

 

[izy]

Care to share the tag writer @_Tim_ you said you used a custom one made also what reader/writer you using or does your program work with any generic

You can lead a horse to water (but if you don't say "here horsey, do you see the water? " It is pretty much useless.)
