Ive been attempting to create a pinout of that 68K. I’m pretty sure what I’ve got so far is accurate although I make no promises as it does get a bit confusing sometimes. If you can shed any light on the pinout of this chip I would be grateful.

—CUSTOM 68K—
pin 7 = A1
pin 8 = A2
pin 9 = A3
pin 10 = A4
pin 11 = A5
pin 12 = A6
pin 13 = A7
pin 14 = A8
pin 15 = A9
pin 16 = A10
pin 17 = A11
pin 18 = A12
pin 19 = A13
pin 20 = A14
pin 21 = A15
pin 22 = A16
pin 23 = A17
pin 24 = A18
pin 25 = A19
pin 26 = A20
pin 28 = A21

pin 27 = VCC
pin 54 = VCC
pin 55 = VCC
pin 56 = VCC
pin 64 = VCC

pin 31 = GND
pin 58 = GND

pin 32 = D7
pin 33 = D6
pin 34 = D5
pin 35 = D4
pin 36 = D3
pin 37 = D2
pin 38 = D1
pin 39 = D0
pin 40 = D15
pin 41 = D14
pin 42 = D13
pin 43 = D12
pin 44 = D11
pin 45 = D10
pin 46 = D9
pin 47 = D8

pin 48 = AS
pin 49 = UDS
pin 50 = LDS
pin 51 = R/W
pin 52 = DTACK

pin 57 = CLK

This post will be updated with any new information if/when I get it.

Well here it is folks.
IDC and Leo have finally released their first wave of shiny new decrypted CPS2 files.
These are for genuine suicided games and should not be used for bootlegging purposes.

All thanks and credits goes to these two guys

Had these dumps for a while. They are from my dead WB3 bootleg board. Not all of the ROMs were dumped as they were dead but some of the others arent in MAME and the MCU was unlocked so Ive dumped that too. Maybe it will help someone revive theirs? This PCB was absolutely huge.

This will probably be the final update of this program.
The HEX2BIN stuff has been removed as I wasnt happy with it and dont have any need for it anymore, plus it was very buggy.
The code has had its final optimisation too.

It continues to serve me well but there is nothing else I need it to do.
