|
|
Emulate a SNES MAX controller serial interface card
|
|
|
|
2 ports (one for each of the two possible joysticks)
|
|
|
|
Latch = write any data to C0n0
|
|
Clock = write any data to C0n1
|
|
Data = read from C0n0
|
|
|
|
n = 8 + slot number
|
|
|
|
Data
|
|
Bit 0 = Not Used
|
|
Bit 1 = Not Used
|
|
Bit 2 = Not Used
|
|
Bit 3 = Not Used
|
|
Bit 4 = Not Used
|
|
Bit 5 = Not Used
|
|
Bit 6 = Controller 2, Active Low
|
|
Bit 7 = Controller 1, Active Low
|
|
|
|
Once data is read, button presses (for each controller) should be stored in the following structure
|
|
Byte 0: B:Y:Sl:St:U:D:L:R
|
|
Byte 1: A:X:Fl:Fr:x:x:x:x
|
|
|
|
The variable controllerXButtons will stored in the reverse order.
