This page contains a listing of some chips that the devil himself created. Mostly these are Micro-Controller Units aka MCU's or custom chips that are probably undumpable, or their contents is in need of exorcising from it's plastic package (i.e. they will need trojaning). However, to trojan them requires code which is then run on the victim, err.. donor PCB, but motivation to write the trojan code is severely lacking due to the extreme difficulty of the task. Even when the trojan is written and run, the PCB can fight it which results in having to re-write the trojan code (sometimes many times), or failure altogether to obtain the info that was required. So sadly, many will remain undumped or unemulated for years, or worse, forever! :-(

Please note the following.....
  • If you would like to donate towards buying a PCB so that we can attempt to trojan it, email me.
  • If you want to donate/loan some PCB's for testing/trojaning, email me.
  • If you can think of a chip that is missing from this list, let me know.
  • Click the thumbnails to see larger pics.
  • Be careful, you might have nightmares about these chips, so don't look for too long ;-)

Knuckle Bash (sound)
Positively identified as an NEC V25+ or V35+

Kaneko Beast

Kaneko Mermaid

DIP 40


DJ Boy and maybe others.
(Possibly an 8041-based MCU)

Taito/Kaneko's Heavy Unit. Identified as an 8051 MCU which is protected.

Hitachi HD647180

QFP 80


Many Toaplan games including Teki Paki, Vimana, Ghox, Whoopie (sound CPU containing ROM)

Gaelco's Master Boy (Main CPU containing ROM) I've attempted to dump this using the newest BP Micro programmer and it's 100% protected.
Update: Dumped by Charles!

Hitachi FD1094
CRACKED! See my FD1094 page for more info.

DIP 64 Many Sega System 16/18/24 games.
(Main CPU; Encrypted 68000 with battery-backed RAM containing decryption tables encased in a block of epoxy resin)

Hitachi H8/3002

QFP 100 Namco System 12. (Sound CPU and protection.)
Fortunately this doesn't contain internal ROM, it's now emulated :-)

C69, C70, C71, C72, C73, C74, C75, C76
C69 Dumped!
C70 Dumped!
C71 Dumped!
C72 Dumped!
C74 Dumped!
C75 Dumped!
C76 Dumped!

QFP 80   All games running on Namco System 11, 22, FL, NA1, NA2, NB1, NB2. (Sound CPU with 16K internal ROM)
This is positively identified as a Mitsubishi M37702. It's trojanable, we're working on it :-)

Dallas DS5002

QFP 80 Many Gaelco PCB's including World Rally 1 & 2. It's an 8051-based MCU. Code for the MCU is contained in a battery-backed and read protected RAM, generally comprising of main program code or patches. The code is encrypted and the key is held inside the DS5002. If you try to read the RAM, the DS5002 detects it and suicides itself and the RAM! REAL nasty stuff......
Update: Code for World Rally supplied by Gaelco. Many Thanks!!

Kaneko MCU's

QFP 74 Jackie Chan, Shogun Warriors, BRap Boys, Blood Warrior + more
(Multi-CPU communications, protection and main program code snippets). Trojaning is possible, we're working on it.

NMK MCU's (NMK004 etc)

QFP   Macross, Gun Nail, Thunder Dragon + more
(Sound CPU with 16K internal ROM) This is likely a Toshiba TMP91P640N (TLCS-90 based), which should be dumpable with the right equipment. Update: Attempted to dump it, but unfortunately the chip is protected. I believe some work is being attempted to simulate it, not sure.

Konami's custom IC's (05xxxx etc)

QFP Many, many Konami PCB's
(Mostly used for protection and graphics functions)


DIP 28 Many PCB's
(Containing read protected code ranging from simple I/O support to lookup tables and code snippets)


SDIP 64   Several PCB's including some Technos games.
(Containing read protected code ranging from simple I/O support to lookup tables and code snippets)


PLCC / DIP Totals 1000's of PCB's
(PALs used as logic devices. CPLDs used as logic and encryption devices, PICs have internal ROM with code that is protected from reading, usually)


Updates will follow as I find out more......
