Williams WPC-95

Cabinet inputs

Addresses 1-8 are the four coin chutes and the four coin-door service buttons in printed row order.

Matrix inputs

Public matrix addresses use WPC column/row notation 11-88, where the left digit is the drive column and the right digit is the return row; values ending in 9 or 0 are not matrix positions.

Fliptronic inputs

WPC-95 always has Fliptronic flipper inputs, so 111-118 are the eight EOS/button positions in WPC_swF1..WPC_swF8 order:

WPC-95 reads that column through WPC_FLIPPERSW95 with a hardware inversion, so the public state is already normalized and must not be re-inverted.

Standard and state outputs

WPC-95 exposes standard drivers 1-28; 29-30 mirror two J111 general-purpose bits; 31 is PinMAME's synthetic game-on state, taken from the driver's fast-flip RAM flag when wpc_set_fastflip_addr is set; and 32 is always zero.

Custom outputs

Above that boundary, 51-64 are the game-specific custom solenoids a driver may publish through its own getSol handler. PinMAME serves as many as the driver's core_tGameData custSol count declares, and a game may use them to expose an already-declared circuit a second time. Attack From Mars is the WPC-95 example with custSol=3. A definition declares only the addresses its own machine publishes.

Matrix conversion

PinMAME applies wpc_sw2m/wpc_m2sw conversion to lamps. ChangedLamps therefore reports public matrix addresses 11-88 rather than sequential indices 1-64, where the left digit is the drive column and the right digit is the return row.

Auxiliary columns

A driver may declare additional lamp columns through core_tGameData lampCol; wpc_m2sw continues the same column-times-ten notation.

Attack From Mars is the WPC-95 example with lampCol=2 for its 16-LED chase board. A definition declares only the columns its own machine populates.
