The PIC16C621A on the M4 cart does not exhibit the same
behaviour as the standard NAOMI/CHIHIRO/TRIFORCE PIC.
In order to understand the exact behaviour of the PIC16C621A,
rtw and the trurip team banded together to get the device decapped.
To verify the dump, the image was burned onto a PIC16F628a
and mounted on the cart. With the replacement PIC in place
the cart boots correctly and passes all ROM tests.
This led to creating a PIC reader that can read M4 type Naomi games using a Raspberry Pi, and Akatsuki Blitzkampf Ausf. Achse has its PIC read out.
