Quoted from CrazyLevi:Yeah you need the board professionally serviced or replaced. You can't "clean it up" with windex or whatever you need to do it pro (cosmetically removing the green stuff won't cut it). Your switch issues are going to get worse and soon the game will likely be unplayable beyond the credit add issue.
Apologies if you ARE a pro and know how to properly clean and remove battery corrosion from a board.
For high level board repairs, I can heartily recommend Clive at the Coin-Op Cauldron. He fixes boards others won't touch (He's the only guy who will fix a Game Plan MPU2, for instance).
For simple things, I do it myself.
I used white vinegar and a toothbrush first to chemically remove the alkaline residue the AA batteries left. I then washed with hot water and scrubbed with baking soda for a little grit, and to neutralize the vinegar. Next I use a little liquid metal polish to clean up the solder points (this is cosmetic only). The last step is to scrub and rinse with 99% ISO alcohol, which removes any remaining water residue. Some will do a distilled water rinse, but I've never felt it necessary. Last step was to clean the cable connection points, especially the cabinet cable, J212, which did have some green gunk on the pins.
Board doesn't look great, but its 100% better than before, and I've halted the corrosion process, so no more damage should occur.
I will report back what happens when I put it back in the machine. For now, here is the board before and after cleaning (I also cut off the battery holder and soldered in remote batteries):
