Top Gunner sprite problem

[covey]

Looking for a little help. Picked up a Konami Top Gunner board. Everything is fine until you try to play the game. The jeep you drive is nowhere to be found. You can tell your moving the jeep, the screen scrolls with you move the joystick. Other things on the screen don't look 100% but are visible. +5 voltage is right on. Pulled all the ROM's and cleaned connections, reseated. No change. Any ideas? Thanks

Sounds like a possible bad video rom.

Any idea which one to look at? If I can narrow it down, i'll tyr to pick one up. Thanks

take a look at the mame driver.  Sometimes they document them in there.
