|

Fancy data decrypter + timer + ?
|
||||
Most creative usage is hooked up in Mighty Guy sound CPU,
|
||||
other games just uses it as a much simpler protection chip providing code
|
||||
snippets.
|
||||
It is unknown at current stage if inside the chip there's a MCU
|
||||
(with internal ROM).
|
||||
|
||||
TODO:
|
||||
- understand how Mighty Guy decrypts data (uses port adjuster in a
|
||||
different way than the other games);
|
||||
|
||||
Legacy notes from drivers:
