Hi all!

I’m not sure if this the correct place to post this, but I’ll give it a shot. I’m diving into MPF in hopes of rewriting some rules on my Capcom Breakshot. Like WPC, there is a serial port connecting the MPU to the driver board, however, it is a 50 pin ribbon cable vs the 34 pin located on the PROC and WPC. 25 pins on the ribbon are used on the Capcom board and the remaining 25 pins are grounded. My question is, is the output data driver specific to that header or could a driver be written to bridge the data output by using an additional header and then a breakout board be used to reroute/combine to a 50 pin? I’m quite certain my terminology isn’t correct so please forgive my ignorance. Any help/direction would be greatly appreciated!

TLDR: I want to connect a PROC to a Capcom Driver Board. Theoretically could it be done via the 34 pin data output rerouted/combined with another header to make a 50 pin connector.

Thanks for your response. I will reach out to him. I was thinking the same thing, but thought maybe something could be done similar to the SNUX board which I don’t think was natively interfaced? This may be beyond my scope of understanding, but I figured it was worth a shot. I’ll report back my findings!

Hey Compy,

Thanks for the reply! I hope compy is a strong bad reference

So for Kingpin did you run PinMAME with KP roms and interface the p3 board and its respective driver outputs or how did you exactly accomplish that lol? I’m very okay with pulling the driver board out and rewriring to a (PD16, PD LED, etc) but after looking at the schematics I thought it might be able to interface the original driver board with some tinkering. Thanks again for the reply and hope to get some answers

You are correct, but from what I understand was that the Capcom Classic boardset essentially combined the 3 driver boards into 1. As far as communication from the MPU there is still a 50 pin ribbon cable on both setups. Maybe it’s more of a complex difference then my limited understanding, but I’m still curious on whether it’s possible.

I understand and agree. Thank you for your input. Im guessing that using PDB boards will make more sense. I’m still interested to know how Compy interfaced the boards with Kingpin.

When we are talking about emulation, are we talking about emulating the mpu/driver board, or what exactly would that entail? I still need to reach out to Gerry and see what he thinks. Busy work week, baby on the way, OOF! I've done a little research on the APC and it looks super promising, especially with the LISY integration. Considering that there isn't a replacement board for Capcom's (and probably never will) I think it would be fantastic if it were supported on either platform. I just finished mapping switches and have a long way to go, but I super glad we are having this conversation.

jabdoa, BTW I want to thank you SO much for your work on MPF, especially the documentation. It is straightforward and super easy to understand. You are doing God's work
