Mercs (US version) lines / jailbars on background and sprite layers

that PCB cannot keep keys, as it's a 92631C-6 and it has the pins for programming the keys hardwired to VCC. You would need to mod it, which is something I don't recommend. See pictures below of original like yours without the black foam and of one converted.

If you want a repro cart that that can hold the keys and works with the multi, send me a PM.

Yeah that.

I think a new c board is about $50 and the repro about $60 which is pretty good value.
