peel it open and take a look... if it's nasty dirty (which it probably is since it's kinda badly designed to keep stuff like dirt and liquids out) get yourself a toothbrush and some 99% isopropyl alcohol and give it a scrub. it may come back to life.

Thanks. I'll try this tonight. It is completely dead so I'm thinking this might work. I assume the menu doesn't show up in test mode because the game isn't detecting it at all. Fingers crossed this fixed it.

yeah that's pretty corroded... and yes, that's typical. the machine joypad isn't really designed to take drinks being spilled on them... which is why they only used them on a couple machines...then stopped using them.
I usually find some pretty gnarly crustys around the IC, but your's looks good. it looks like just the power wire had corroded itself off... it's probably still good.
at this point... you can either
-find a scrap board somewhere with the same connector and replace it.
or do what I'd do...
-just chop off the wires and solder it directly to the board.
(but i'm crazy and can do stuff like that. your mileage may vary)
Fattdirk:
I soldered the wires directly to the board because this is a beater anyway and it didn't work. The picture didn't show all the corrosion but it's pretty bad. Without a schematic I might try and buzz out some of the traces but I'm not sure if I even care that muce because the joypad doesn't seem to add much to the game.

Do you want to sell that board that you have there?
