I'm working on a BattleShark - the game has been online for around 2 months now, and was giving little trouble other than a rare coin mech jam.
That changed last week - the arcade took a power surge, and this game was knocked off line. I scoped the power supply - the DC was solid - no AC ripple at all. The -5 was a little low, so I bumped up the +5 to 5.2, and that made the game stable for a day.
Now it's back to the previous trick - the screen goes all yellow, or the CPU resets and goes back online.
Any suggestions on where to start with this one would be appreciated. I started with the power supply, and the obligatory pull / reseat of the connectors, with no success. I'm starting to think I might be seeing a RAM failure.
