New arrival: DoDonPachi Dai Ou Jou

I sold a few games last week to finance something new. And then, from out of nowhere, Dai Ou Jou came up for sale at the shmups forum. When opening the case i noticed that battery was still on the board and it looked like it had just started to corrode. The PCB was free from acid, but I cut the battery of directly to be on the safe side.
