The fun thing is that the main CPU actually calculates the combinations then it routes to this port
|
||||
thru packet writes, 0xd* starts the packet, 0xe* ends the packet.
|
||||
I'm fairly sure that this thing can do a lot more, the POST check makes me think that 0xd9 is actually a result of a RNG.
|
||||
For now we'll emulate the bare minimum to let this game to work, obviously we need tests/tracing on the real board to understand
|
||||
what it is exactly and what it can possibly do.
