Golden Axe by channelmaniac
From Arcade Otaku Wiki
Symptom: Garbled/Missing Background Graphics
Swapped out the broken socket on IC21 with spare socket from empty IC23. Reset jumpers S1-S6 for proper ROM types on daughter board. Fixed a bent pin on the custom encrypted CPU to finish the repair.
Symptom: Graphic corruption
Game had garbled graphics that would get better if the ROMs on the daughterboard were reseated, then come back later. Resoldered IC3 on the bottom of the daughterboard and tested.
