    Help - Other QR code - Can it be reverse engineered?

    The motors use 0x0C for up, so you might want to try that instead of 0x05. Were you modifying only the orientation bits of the outside ring? It's...

    Help - Other QR code - Can it be reverse engineered?

    It's interesting that the bot you control changes from the one in the middle to the one in the lower corner. I wonder if the game always uses the...

    Help - Other QR code - Can it be reverse engineered?

    I think you're on to something. The QR code data always begins with 0x 01 13 0D FC 78 01 ED. Also, DEFLATE (e.g. zlib) streams end with a 4-byte...
