Capcom CP System (CPS-1)

Capcom's first major arcade platform (1988), origin of Final Fight, Street Fighter II, Ghouls'n Ghosts… A-board + B-board architecture. Most CPS-1s do not "suicide" — but the CPS Dash / CPS-1.5 games (QSound, Kabuki chip) do have a security battery.

Block	Chip	Clock	Role
Main CPU	Motorola 68000	10 MHz (12 MHz on late boards)	game logic
Sound CPU	Zilog Z80	3.58 MHz	drives the sound
Sound	Yamaha YM2151 (FM) + Oki MSM6295 (ADPCM)
Graphics	2 CPS-A customs + CPS-B-21		tilemaps + sprites, priorities & colour mixing; the CPS-B-21 holds per-game registers (light protection)
Video			384×224, 4096-colour palette

On CPS Dash / CPS-1.5 (QSound): adds QSound + a Kabuki sound CPU (modified Z80 @ 8 MHz, encrypted).

CPS-1 vs CPS Dash (CPS-1.5)

• Standard CPS-1: A-board + B-board (removable daughterboard = the game). No suicide battery.
• CPS Dash / CPS-1.5: 4 nested PCBs in grey cases (A/B/C-board), stereo QSound, and an encrypted Kabuki chip → security battery (see below). Games affected: Cadillacs & Dinosaurs, The Punisher, Slam Masters, Warriors of Fate.

The "suicide" (CPS Dash / Kabuki only)

The Kabuki games store a key in volatile RAM kept alive by a battery. If the voltage drops below ~2 V, the key is lost → the game is inoperative (dead).

• Non-QSound CPS-1s do not have this mechanism.
• The Kabuki encryption has been cracked → phoenix ROMs (decrypted, run without a battery) and preventive battery replacement. (detailed procedure to be added.)

Common faults

Symptom	Likely cause	Lead
Dead Kabuki game	Flat battery (suicide)	Phoenix ROMs, or battery replacement / re-key
Corrupted / missing graphics	B-board contacts, customs, ROMs	Reseat, connector cleaning
No sound / partial sound	YM2151 / MSM6295 / Z80 (or QSound)	Sound-stage diagnosis
Wrong colours / priorities	CPS-B-21 setting	Check custom config
No image	A-board (power, customs)	Check power, JAMMA contacts

Conversions

• Changing game = swap / reprogram the B-board (common on CPS-1).
• Phoenix (Kabuki games): frees you from the battery.
• ⚠️ Do not host ROMs — method only.

EPROM repair: program on the B-board, 27C010 (128 KB) → 27C040/27C4096 (512 KB) depending on the game → game-by-game program EPROM table.

Mods

• CPS Changer: Capcom's home adapter (≈ supergun) to play CPS cartridges at home.
• Native RGB via JAMMA.
• Region / config: dip switches + B-board.

Modernisation & mods

The common ground for every JAMMA board

Video, power, control panel and upscalers depend on the cabinet rather than the board: everything is centralised in Modernising a cabinet. To run the board outside a cabinet (at home, on a display): supergun.

• Anti-suicide 🟠: some games/variants of this platform do suicide (battery-backed key) — see the dedicated section above to find out whether yours is affected. If so, the durable route is de-suiciding → conversions and de-suiciding, not merely replacing the battery → save batteries.
• Storage 🟡: the game lives in EPROM/mask ROM on the board. Changing or restoring a game means reprogramming the EPROMs (and, for a mask ROM, using a pinout adapter) → EPROM method.
• Media preservation: replacing the original storage, multicarts, ODEs and modern options by family → PCB preservation hub.
• Scan rate 📺: ~15.62 kHz / 59.6 Hz — standard resolution, a classic 15 kHz chassis is fine — the most common JAMMA case → tri-sync and upscalers. (Computed from the MAME sources — capcom/cps1.h (8 MHz / 512) — pixel clock ÷ htotal.)
• FPGA / emulation: see the Emulation & FPGA section below.

Repair (technician)

• Suicide? No — the CPS-1 has no battery keys (it's the CPS-2 that suicides). A dead CPS-1 board is a real hardware fault.
• CPS customs (A/B/C): corrupt sprites/planes = video RAM + buffers first, the custom next (donor). CPS-1.5 / Dash = variants with different customs (+ QSound).
• Sound: Z80 + YM2151 + OKI6295 (QSound on CPS-1.5) — diagnose the sound stage.
• Capacitors: recap PSU + audio filtering. Oxidised EPROM sockets: turned-pin socket.

DIP settings ✅

55 games on this platform, settings extracted from the MAME sources (INPUT_PORTS_START blocks). The Position column gives the switch's physical reference on the board (SW2:!3,!4 = bank SW2, levers 3 and 4) — which is what lets you set it up without the paper manual. Games are sorted by MAME set name.

Check against your own board

These settings apply to the game and revision described by MAME. One title may have several DIP sets depending on region or revision, and some systems use soft-dips (settings in memory, via the test menu) rather than physical switches. In case of a discrepancy, the board's silkscreen and the test menu are authoritative.

Emulation & FPGA

• MAME: the CPS-1 family (Capcom drivers) has long been emulated.
• FPGA / MiSTer: the jtcps1 core (Jotego) rebuilds the CPS-1 in hardware logic on MiSTer — useful for preservation and for studying the CPS-B-21. The CPS Changer ("console" version) shares this hardware.

Review & corrections

How this space is used

Spotted a wrong value, an outdated procedure, a chip reference that does not match your board? Say so here, with what you observed (model, board revision, serial number, measurement). Every report is cross-checked against a source before anything changes — an unverifiable correction is published as “reported by …, not cross-checked” rather than silently applied.

Reading is open to everyone; posting requires signing in with Discord. Reports from the wiki's declared reviewers are handled first; anyone else's are read too, but go through a human before anything is changed.
