Hey Everyone,
I recently picked up a jamma Galaga bootleg that has the wrong colors. I know my monitor is fine because my other boards look great. My guess is that I'm missing the color blue because the bee looking guys have green wings and a pink body. I'll attach some pictures. The bloom on my camera makes it hard to see when they're all in formation but I got one shot where you can see his pink body.
So I guess my question is if Gallag ever had color variants? Or maybe theres some deoxit and lots of reseating chips in my future? Reading about Gallag/Galaga repairs has been quite the rabbit hole.
Everything else is great! It plays like it should, the starfield isn't a mess, theres no pink hue on the ship/white sprites and the sound is good. That should rule out ram issues, right? It passes those tests, but I read that test mode isn't particularly useful on Galaga.
I've gone as far as checking continuity but I haven't found any broken traces on the color lines. Any tips are appreciated! I consider myself to be a competent mame cab enthusiast (I've built a few machines) but troubleshooting actual arcade pcbs is new territory for me.
Thanks,
