Hi ,
We're working on hacking some Powkiddy handheld game players ( X16 and J6 ) that use the ATJ2279B and what seems to be a rebranding of it, the ATS3603.
I was wondering if anyone has access to some information regarding this. I was able to find that the SDK being used is this "usdk227c". The devices themselves seem to be called "ch7968_v1" and "CD3670".
We have the firmware for the Powkiddy X16 but we could really use the firmware for the Powkiddy J6 ( "CD3670" but also called the X3 ) , if anyone has any means of getting these that would be great.
Also this SDK , the "usdk227c" would be really nice to have.
Not sure it helps in any way but both of these devices seem to have been modified by a Mr Huang, I'm offering a reward for finding him , $10 for now

Here's the full string :

Thank you very much.
