/* note on PIC protection from ElSemi (for actually emulating it instead of patching)
The PIC uses a software UART bit banged on a single output pin of the main CPU:
the data port is bit 0x20000000 on the PIO register, the same register where the EEPROM control lines are. The serial data is transmitted at 8 data bits, even parity, 1 stop bit. It's probably
tricky to get it working properly because it doesn't rely on a clock signal, and so, the pic and main cpu must run in parallel, and the bit lengths must match. The pic bit delay routine is just a loop.
also it seems that bit 0x40000000 is the PIC reset.

The plastic stabilizers are screwed in to the motherboard via the 2 holes at the sides of (pci?) slot connector from the bottom and have groves that you use to slide the game into.I see what you're saying now.Yeah I got his soccer game and it's in fantastic condition. I already had CoK or I would have bought his as well!
I really wanted that one you got, and I figured since you are converting it anyway, wouldn't you rather have one with a cartridge cover?
It looks like the cartridge cover would only get in the way with the vertical orientation of this motherboard. Ack was telling me that these ones snap in on the bare board. So we'd need to swap the whole set-up.
Part of the appeal of this one is its just one rom to remove (less room for error with fiddly smd stuff). Is the soccer game the same PCB? I know at least one in MAME looked to be *entirely* different.
Could be, but that is a 28 pin device... http://ww1.microchip.com/downloads/en/DeviceDoc/39016B.pdfMaybe someone misread 16c72T?
My mistake.Could be, but that is a 28 pin device.
There is one motherboard + crystal of kings on eBay for 800 Euro...
Hold my beer...And that guy is crazy. The last couple were under 300usd at open auction.
I believe it is possible to make games run on real cart hardware without a PIC (with patching).Maybe you can just dump the patched program from mame and burn that, and not use the pic at all? Depends on how the pic is integrated into the system,
