FIXED!!!!! MVS Repair: Warped PCB repair ideas? (No longer warped, still bad sound)

[rewrite]

I have a BK1 board you can have.

Its originally from some bootleg from a long time ago. It looks in good condition, but can't say for sure its 100% functional.

Thanks! I'd appreciate that a lot!

I just realized I still have a board to send back your way, I'll toss it in with the chips from the group buy order if that works for you.

We are up and running! I put back in the V1 and V2 mask roms.

So in the end:

- The PCBs needed to be heated and flattened out.
- Neo 273 needed to be reflowed.
- P1, SP2, M1, and V3 all needed replacing. Not confident S1 needed replacing but I did it just the same.

One game down!

Going to roll this knowledge into the non-working Metal Slug 5 coming later this week!

Thank you all for your assistance!

I've "fixed" one with hot air. Heat it up, press the middle against the edge of a table so that the board is flexed in the opposite direction (slightly over), and let it cool.

You may have to reflow SMD components afterwards. I didn't.

I just tried this with a badly warped ZN-2 and it worked great. Took a couple of passes to get it more even, but much better than before. Thanks for the tip!
