RE: Spy Hunter help

   There should be a test switch inside of the coin door, IIRC.

Yes, screens cycle continuously, so it might be the watchdog timer. I'll
check that.

The only test mode I saw was on the sound board. Does that also check
ROM and RAM on the CPU board? Or - is there another test mode on the
CPU board?

The next step is testing the ROM images.

Also, I read somewhere that VBATT needs to be present. Does anyone know
if that's true? The batteries are dead...

Thanks.

  The flashing part (background/border objects) with a tight/small

that over and over again? If yes, is the CPU being reset right shortly
after the crosshatch? It may be watchdogging...

  You did not say either way, but the game does have a test mode. Did
you flip that switch to see if it will enter test?

  From your description, my first thought is a ROM issue...

  Peace!
