Damn that sucks! Sounds like a code error and not a rom banking issue? (sound "code roms" speed maybe?)Looks like I spoke too soon. The first play through is fine but if you die and start over the sound messes up, the speech is too quiet and the music stalls or repeats.
I thought maybe it was the gal I used as it was slower than the original pal (250ns vs 150ns) but even erasing and reusing the original pal chip it still does the same thing.
I noticed original boards have the two bodge wires shown in the conversion guide but also have an additional two, I'm thinking maybe these are needed. If I can figure out where the wires go from the low res pictures I've found I'll try it and report back.
The file is for use with a gal22v10 and works fine otherwise I wouldn’t have shared it.I finally got around to trying the Gunlock / Ray force conversion today, everything worked fine apart from the sound. I made the mistake of thinking the above file was IC14 converted to 22v10. After downloading the IC14 jed from jammarcade and sticking it on a gal20v8 (not palce20v it works 100%.D29-14 file attached in GAL22V10 form
Tested the file on a new chip in my board and works fine
Had the same issue with the sound. Using the jed file from jammarcade fixed it for me. Don't use the mame file. https://www.jammarcade.net/wiki/index.php?title=Ray_ForceIf you get past the colour ram issue I'd be interested to hear if you have any speech / music issues. I've converted two pcbs to ray force now and both have quiet speech and crashing / repeating music when you die and start another game.
