Repairer: channelmaniac

Symptom: Dead. Garbage on screen

Straightened a bent pin on the BIOS ROM, powered up the game, and received a SYSTEM ROM ERROR message. Programmed a new BIOS ROM, booted the system, and received a Z80 ERROR message. Replaced the Z80 CPU and tested. Splash screen sound was normal, but the games sounds were horribly mangled. Repaired a damaged trace to finish the repair and tested.
