Data East/Sega System

Public matrix addresses

Data East uses PinMAME's sequential, column-major 1-64 switch namespace inherited by MACHINE_DRIVER_START(s11) from MACHINE_DRIVER_START(PinMAME). The registered conversion is core_swSeq2m(n)=n+7, so column=((n-1)/8)+1 and row=((n-1)%8)+1 for public address n (src/wpc/core.c core_swSeq2m/core_m2swSeq; src/wpc/s11.c MACHINE_DRIVER_START(s11)). It is not WPC's column-times-ten notation.

Data East matrix strobes are one-hot. pia4b_w keeps only the first asserted strobe bit when locals.deGame is true, and pia4a_r passes that selected column to core_getSwCol (src/wpc/s11.c). Public address numbering remains sequential; this hardware detail matters when interpreting traces with malformed multi-bit strobes.

Cabinet column and diagnostics

DE_COMPORTS supplies ordinary column 1 at public addresses 1-8: tilt=1, ball tilt=2, start=3, coin 1-3=4-6, slam tilt=7, and no defined cabinet input at 8 (src/wpc/s11.h). These are part of the same switch namespace as the playfield matrix. A game using S11_MUXSW2 may overwrite public switch 2 with the live mux-relay state in SWITCH_UPDATE(s11); identify switch 2 from the game-specific driver and manual rather than assuming it is always a physical ball-tilt switch.

Only two negative service addresses exist on Data East hardware:

Williams-only CPU and sound diagnostic addresses -5 and -4 are not part of the Data East contract. DE_COMPORTS2 changes the later green button from toggling to momentary input behavior, but its public address remains -6 (src/wpc/s11.h).

Inversion and extensions

The profile's inversion_applied_by_emulator field means consumers use the public LibPinMAME state as delivered and do not perform a second inversion. It does not assert that every game has a nonzero invSw mask. The common INITGAMES11 Data East initializer zero-initializes that mask; custom drivers must be checked individually. A nonzero hw.swCol adds game-specific columns above the base 1-64 range and must be declared by that machine rather than inferred from this base rule.

Country jumper

The shared driver exposes one DIP-style configuration bit at public address 0: the physical country jumper read by pia2a_r as core_getDip(0)<<7. Data East input definitions reuse the shared one-jumper machine driver (src/wpc/s11.c pia2a_r and MACHINE_DRIVER_START(s11); src/wpc/s11.h shared country-jumper declaration). It is not a bank of operator DIP switches.

Address map

The public namespace is a platform-sized outer bound; a machine definition must mark its actual populated, virtual, and unused addresses from its own driver, manual, and trace.

Data East general illumination is not a separate LibPinMAME GI channel. The shared driver types the appropriate per-game ordinary solenoid output as an AC bulb/relay; most Data East games use output 11, but the exact populated outputs and electrical types come from the game's own MACHINE_INIT(s11) name block and manual. Bind those devices to pinmame.output.solenoid with machine output kind gi.

Special-solenoid permutation

PIA-driven special solenoids are active-low at the PIA handler and gated by locals.ssEn. Data East selects ssSolNo[1]={3,4,5,1,0,2} in setSSSol, producing this exact handler-to-public mapping (src/wpc/s11.c):

Do not infer SP1-SP6 physical labels from those public numbers. When a game instead populates sxx.ssSw, the VBLANK path indexes those slots sequentially as public 17+ii and does not apply the PIA permutation. Manual circuit identity, PIA handler, sxx.ssSw slot, and public output address remain separate facts until a game-specific trace reconciles them.

K1 A/C mux

updsol() detects the game-specific mux relay—public 10 for the common INITGAMES11 Data East initializer—and, while it is active, copies the low driver byte from public 1-8 into public 25-32 instead. These are alternate circuits behind the same eight transistors and K1 relay contacts, not sixteen independent drivers. The machine's manual and working VPX script decide which A-side or C-side device is physically wired to each pair. Playboy 35th sets S11_MUXDELAY, so pia0b_w processes the previous controlled-driver byte and delays the mux decision by one IRQ; traces must preserve that timing rather than expecting same-callback switching.

Auxiliary outputs and flippers

For Data East DMD generations whose initializer sets S11_PRINTERLINE, pia2b_w writes an eight-bit printer-line/auxiliary byte into internal PWM slots 41-48; core_getSol, core_getAllSol, and core_getAllPhysicSols expose those slots as public 37-44. The 128x16 path inverts that byte, while the 128x32/192x64 path does not. The reviewed alpha initializers do not enable S11_SNDOVERLAY. Never infer a physical device, availability, or polarity from the shared range alone.

The common Data East driver macros use FLIP_SWNO(...) without FLIP_SOL(...). core_updateSw therefore fabricates public 45-48 from the configured left/right cabinet switch state only while public 23 enables the flippers. They are useful controller states for a recreation but do not identify four independently controlled driver-board transistors or prove the physical EOS/power-winding polarity.

Standard matrix

MACHINE_INIT(s11) publishes 64 + hw.lampCol*8 lamp states. The standard Data East matrix is public 1-64, numbered column-major with the same sequential conversion as switches: column=((n-1)/8)+1, row=((n-1)%8)+1. pia1a_w supplies active-low rows and pia1b_w supplies columns to core_write_pwm_output_lamp_matrix (src/wpc/s11.c).

A nonzero hw.lampCol adds game-specific columns above 64; this base profile does not silently claim them. General illumination is not part of this lamp group or a separate GI channel on this driver—it is represented by the game's ordinary solenoid/relay output.
