Do you know anything about switch game cards? I'm trying to use reverse engineering in one

What game cards? NFC and amiibos? Currently I know how to read them but I've trying to write some data. I almost have the protocol done just need to do some final touches

[Arthurfogo7]

Yeah, I want to know how to read them, since I think the content is encrypted. Can you teach me briefly?

[german77]

Yeah most of the content is encrypted. Only a few data like the model_info is in plain format. For encryption see https://github.com/yuzu-emu/yuzu/blob/master/src/core/hle/service/nfc/common/amiibo_crypto.cpp

amiitool is a good tool if you want to skip all the complicated stuff and just convert the tags to plain format. https://github.com/socram8888/amiitool

For reading the raw data from a joycon it's a bit more complicated but at the end of the day you just need to send a few commands to enable it and wait until a tag is in range. This is done here
https://github.com/yuzu-emu/yuzu/blob/master/src/input_common/helpers/joycon_protocol/nfc.cpp

Here is a brief dump of the commands used on the switch while reading an amiibo tag

Thank you for the info. I have a last question, I don't know if you will understand what I mean, but do you know if it is possible to extract data direct from the NAND chip inside the cartridge? With a adapter or something

[german77]

Oh lol I completely missed the topic. Game cards as game cartridge. Suddenly the topic makes more sense. I was talking about joycons since most RE here is for that.

Cartridges are encrypted with a special key different than game encryption that prevents from reading the contents properly. So far the only reader is the switch as I never heard of an external adapter before. Sadly I don't know much about this topic.
