Now that I finished the other MK2 project, i'm starting to mess with my spare boards.

I have an MK1 that boots fine but has a sound issue... The game sounds are ok but the voice that states the fighter's name, who wins, fatality etc is having an issue.

See video here:



Any ideas where to start checking?

Zen? Brood? thoughts?
 
could be a corrupt chip, or possibly one in the wrong location.
 
If it's spitting out the wrong sounds, it's a rom issue. Remove, clean, and reinstall them. See what that does.
 
are you handy with a soldering iron? i'd say hit every leg on the bottom of the board just for giggles as well as change out the ribbon cable. other than that the use of a logic probe is the next step and i don't have a ton of experience with that (i've been slacking on learning that bit).
