Hey guys, I'm hoping to learn some basic repair skills for these carts. I've got a decent bit of experience with pinball repair, and am comfortable soldering/desoldering anything you'd find on an MVS board shy of surface mount chips.
I've got a Galaxy Fight that plays fine, and the sound is mostly present, but is largely garbled. I've looked the boards over, and while it looks like there may've been moisture or something on the boards at one point, I don't see any corrosion or trace damage or anything like that. With that in mind, I've concluded I likely have a bad sound ROM. Does that sound right? This would be a V rom, correct?
Is there any good way to diagnose this, or should I just start shotgun replacing these ROMs? If I just need to start replacing ROMs, what EPROMs do I need? Bonus points if you can direct me to something from this list: http://www.arcadecomponents.com/memory.html?page=4
Thanks in advance!
