Williams/Bally WPC Fliptronic

Addresses 1-8 are the four coin chutes and the four coin-door service buttons in printed row order. 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. This generation always has Fliptronic flipper inputs, so 111-118 are the eight EOS/button positions in WPC_swF1..WPC_swF8 order: 111 lower-right EOS, 112 lower-right button, 113 lower-left EOS, 114 lower-left button, 115 upper-right EOS, 116 upper-right button, 117 upper-left EOS, 118 upper-left button, exactly as on WPC-95. A driver may declare one additional custom switch column through core_tGameData custSwCol (CORE_CUSTSWCOL = CORE_STDSWCOLS = 12 internally), which PinMAME reports publicly at 91-98; a definition declares this range only when its own machine populates it. Unlike WPC-95, this generation's WPC_FLIPPERS register read (core_r offset WPC_FLIPPERS) unconditionally returns the bitwise complement of the flipper switch column regardless of hardware generation, so the public Fliptronic state is already normalized here exactly as it is on WPC-95 via WPC_FLIPPERSW95; a recreation must not re-invert either range.

This generation 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; 32 is always zero. 33-36 are the Fliptronic upper-flipper circuits (33/34 upper-right power/hold, 35/36 upper-left power/hold) and games may drive non-flipper devices through them. 45-48 are the Fliptronic lower-flipper circuits (45/46 lower-right power/hold, 47/48 lower-left power/hold), identically addressed to WPC-95. UNLIKE WPC-95, this generation has no integrated LPDC board, so 37-44 are not a duplicated general-purpose output range: pinned PinMAME's core_getSol dispatch (src/wpc/core.c, the "37-44 WPC95 & S11 extra" branch) only serves that range for GEN_WPC95/GEN_WPC95DCS/GEN_ALLS11, and returns nothing for this generation, so 37-44 are simply unused address space here unless a specific driver's own getSol hook independently claims part of it. 49 is PinMAME's simulator-only ball-shooter channel and 50 is reserved before the first custom-output boundary (CORE_FIRSTCUSTSOL = 51). Above that boundary, 51 upward are the game-specific custom solenoids a driver may publish through its own getSol handler, up to as many as its core_tGameData custSol count declares; a definition declares only the addresses its own machine publishes. A driver's own custom-solenoid numbering (e.g. an external auxiliary board's own silkscreened item numbers) is not the same as this public address space, and printed manual item numbers for such a board must be captured as a manual.address alias rather than assumed equal to the public solenoid number.

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. A driver may declare additional lamp columns through core_tGameData lampCol; a definition declares only the columns its own machine populates.

Public GI addresses are zero-based 0-4 and correspond to the manuals' printed strings 01-05.
