Re: JPAC and MiSTer Highly Saturated Calibration or MiSTer?
It looks like I'm having the same over-saturation issues you guys are with my JPAC, a couple questions: What rating trim pots are those? 10k? Did you take the RGB lines from the chip out of circuit? Cut/Solder traces back to RGB out on JAMMA Connector? It's been a while, sorry for the late post. Maybe this is good for somebody's situation, I made ...

Re: JPAC and MiSTer Highly Saturated Calibration or MiSTer?
In the end I sorted this out by adding trim pots to the R / G / B lines out of the JPAC to the JAMMA harness. Just a small adjustment brought the image into normal range. I've found this also useful for arcade boards that output video too "hot" for a certain monitor (CPS2 in my case), it's easy to add to an extension harness. IMG-6495.jpg

Re: JPAC and MiSTer Highly Saturated Calibration or MiSTer?
I have the exact same issue. I'm thinking that this is a result of the video amplifier in the J-PAC, that is meant to boost a PC video signal from 0.7 to 5V. I haven't found a way to disable the on-board amp, maybe there's a way to attenuate the signals between the IO board and J-PAC? Any ideas are welcome.
