Raizing / Eighting (8ing)¶
Raizing (studio 8ing), founded by ex-Toaplan staff: the hardcore cult danmaku — Battle Garegga, Armed Police Batrider, Battle Bakraid, and the Mahou Daisakusen series (Sorcer Striker). 68000 + GP9001 VDP hardware (the direct Toaplan legacy), legendary scoring.
Identification¶
| Field | Value |
|---|---|
| Manufacturer | Raizing / Eighting (8ing) |
| Years | 1993-1999 |
| CPU | Motorola 68000 |
| Video | GP9001 (custom VDP, inherited from Toaplan V2) |
| Sound | YMZ280B (Garegga/Batrider/Bakraid) or YM2151 + OKI |
Architecture¶
| Block | Chip | Role |
|---|---|---|
| CPU | Motorola 68000 | logic + bullet patterns |
| Sound CPU | Z80 | drives the sound |
| Sound | YMZ280B (PCM) or YM2151 + OKI6295 | music (Battle Garegga's cult OST) |
| Video | GP9001 (Toaplan custom) | planes + sprites, high object count |
Raizing reuses Toaplan's GP9001 (the founders came from there) — hence the visual
kinship with Batsugun. Battle Garegga (1996) is a scoring monument (rank system)
and Batrider pushes the concept further still. Emulated in MAME
(toaplan/toaplan2.cpp).
Notable games¶
Sorcer Striker (Mahou Daisakusen, 1993), Kingdom Grandprix (Shippu Mahou Daisakusen, 1994), Battle Garegga (1996), Armed Police Batrider (1998), Battle Bakraid (1999). The cousins Dimahoo (Great Mahou Daisakusen) and Brave Blade run on CPS-2 and ZN respectively.
Common faults¶
| Symptom | Likely cause | Lead |
|---|---|---|
| Corrupt sprites/planes | GP9001 / RAM | RAM test, contacts; rare custom |
| No/partial sound | YMZ280B / Z80 | Sound-stage diagnosis |
| Lost settings/scores | EEPROM / battery | Reprogram/replace |
| Danmaku slowdown | (often deliberate) | Compare to a reference |
| No image | Power, 68000, harness | Base diagnosis |
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.
- Battery 🟢: a save battery is fitted (settings/counters/RTC). A leaking battery corrodes traces — check and replace it before it leaks → 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 📺: not yet measured. The matching MAME driver does not expose its screen parameters in a form our extractor can use — no value is guessed here. Check what your monitor accepts before connecting → tri-sync and upscalers.
- FPGA / emulation: see the Emulation & FPGA section below.
Repair (technician)¶
- GP9001 (inherited from Toaplan V2): an unobtainable custom VDP → corrupt planes/sprites = video RAM + buffers first, the custom last (donor).
- Z80 sound CPU + YMZ280B / YM2151+OKI: silent/partial sound = diagnose the stage (Z80, sound ROM, DAC); recap the amp and filtering.
- Capacitors: recap the sound stage and PSU filtering.
- Oxidised EPROM sockets: re-tin / turned-pin socket.

DIP settings ✅¶
15 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.

Procedure — a dead board, step by step ✅¶
What this adds
The general method lives in PCB diagnosis. This is its application to this platform: the same order, but with the values actually expected here, so you do not have to go back and forth.
Tools: multimeter, oscilloscope (or frequency counter), current-limited bench supply, desoldering braid. → Tooling
If the board is still in a cabinet
A CRT holds its charge with the machine unplugged. → CRT safety
1. Inspection, power off. Corrosion, cut tracks, oxidised EPROM legs, leaking SMD capacitors, dubious earlier repairs.
2. The connector, before anything else. A large share of "dead boards" are a contact problem, not a fault. Clean the contacts with isopropyl alcohol and reseat — not with an abrasive eraser on a gold edge, which takes the plating off and brings the problem back worse. It costs two minutes and settles the question.
3. Power, measured on the board. Aim for +5.0 V measured as close as possible to where power reaches the board — not at the PSU output: the drop is in the loom, and that is exactly what makes a board boot on the bench and not in the cabinet. Where you probe depends on this board's connector — JAMMA edge, JVS loom or a proprietary harness — plenty of makers kept one long after JAMMA arrived — see Identification above. → Wiring Check −5 V and +12 V too if the sound stage uses them. Suspected short: bring it up current-limited and find the hot spot.
4. /RESET. It must release after power-up. Held low = the CPU never starts. A 1–2 Hz loop is not the reset circuit, it is the watchdog: the CPU is crashing at boot, so look at the bus, not at the reset.
5. Clocks. There is no measurement table for this platform — MAME's sources yield nothing usable for it. Any frequency quoted under Architecture on this page serves as a marker; otherwise compare against a working board rather than against a number: an invented value condemns healthy parts. → PCB diagnosis
6. Bus. Activity on the main CPU's address lines tells you whether it is running or frozen. Frozen with good clocks and good reset → work RAM, bus buffers, ROMs.
7. It boots but the picture or the sound is wrong — that is another job: see Common faults on this page, then signal tracing.
Emulation & FPGA¶
- Emulation: MAME (
toaplan/toaplan2.cpp, shared with Toaplan V2). - FPGA / MiSTer: tied to the Toaplan V2 cores (GP9001) — support per progress.
EPROM repair¶
68000 program in 27C040. Ex. (MAME toaplan/raizing.cpp, raizing_batrider.cpp): Battle Garegga / Shippu Mahou Daisakusen = 2× 27C040 · Sorcer Striker / Mahou Daisakusen = 1× 27C040 · Batrider = 2× 27C040 · Battle Bakraid = 4× 27C040. Toaplan-V2-like base.
Lineage¶
Direct descendant of Toaplan (same teams, same GP9001); on the danmaku side, cousin to Cave and Psikyo.

What the manufacturer's manual establishes — Battle Garegga ✅¶
Read off the Raizing / 8ing manual archived below, in the 設置の概要 ("installation overview") box:
| Item | What the manual writes |
|---|---|
| Connector | エッジコネクター — edge connector, JAMMA規格 / JAMMA STANDARD |
| Screen | タテ画面 / VERTICAL SCREEN |
| Stick | 8WAY JOYSTICK |
| Button A | SHOT (ショット) |
| Button B | SPECIAL WEAPON (スペシャルウエポン) |
| Button C | CHANGE FORMATION (オプション操作) |
⚠️ An operating limit, stated in black and white: ※クレジットは10以上投入できません — the machine will not take more than 10 credits. That is not a fault, it is the intended behaviour; an operator who does not know it will suspect a failing coin mech.

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.
