Midway Pinball 2000

Playfield matrix

Addresses 11-88 use column-times-ten plus one-based row notation. Values ending in 9 or 0 are not matrix positions. PinMAME translates those public addresses through p2k_sw2m and p2k_m2sw.

Dedicated inputs

The board's 24 direct inputs are exposed as three public columns: printed D1-D8 become 91-98, D9-D16 become 101-108, and D17-D24 become 111-118. They carry coin, diagnostic, EOS, cabinet, and action-button inputs.

Polarity

P2K publishes mixed raw public levels. Every switch in the per-game opto list is active-low (0 active/beam blocked, 1 inactive); SWITCH_UPDATE(p2k) refreshes those optos to 1 each frame before game/model activity drives them low. Grounded contacts outside that list are active-high (1 closed/active). The profile's inversion_applied_by_emulator field means consumers use the public state exactly as delivered and must not apply one controller-wide inversion; it does not claim that every public input is active-high.

Board drivers 1-32 retain their number. Board drivers 33-36 are the lower-flipper circuits and are exported at public solenoids 45-48. Board drivers 37-48 are exported as custom public solenoids 51-62. Public ranges 33-44 and 49-50 do not represent Pinball 2000 driver-board positions and are intentionally excluded.

The public address is a zero-based bit index in the sixteen exported lamp bytes. For the manual's column, bank, and row notation use address = (column - 1) * 16 + (bank B ? 8 : 0) + (row - 1). Thus manual 11A is public 0; there is no one-based offset. PinMAME's machine-test walk verified all 128 positions.
