I think I fixed the sound problem, I threw a second voltage regulator on the reverse side instead of trying to power both sides with one and now it's stable.
e:Yeah I've done like 4 attract cycles and there's been no issues.
I agree with stencil + solder paste, that's the key to a really clean install. Although you still need to run jumpers for proms.
btw if you're looking for the proms this guy sells them extremely cheap. $7~ for 10. Everyone else does 5 for $15.
These are salavaged proms though, so you will have to erase them which adds some time when programming them.

Oh I almost forgot, thanks @MetalliC for posting detailed instructions how to do this. Now I just a need to pick up a Capcom I/O and I can play CVS2 with only one PSU.
