A/B board set came from a local auction buy. Battery was rolling around inside cart.

Removed ROMs 3-8, erased them, and reprogrammed them with suicide free code. Board booted but had distorted sound and incorrect graphics. Programmed and installed missing BGSG1 PAL on daughter board. Reset improper jumpers JP10 through JP29 and board booted with proper sound and graphics. Tested game.

NOTES: BGSG1 PAL controls sound ROM decoding. BGSG2 PAL controls graphic ROM decoding. Board appears to have been a swap where someone was attempting to fix another cartridge. That's the only explanation I could think of for all the incorrect jumper settings and the missing PAL.

Removed batteries from the C board and Q sound board. Modified both boards to use phoenix code and replaced the necessary EPROMs with faster ones using the phoenix code. Tested.

NOTE: Do not use any non-AMD EPROM slower than 150ns and AMD EPROM slower than 120ns when phoenixing CPS1 or CPS1.5 games as they will experience random crashes.
