Today we have some new PAL dumps.

‘coolmod’, one of our finest contributors, sent in different dumps, all are untested since they come from not working PCBs.We had from him dumps from these boards:

  • Gals Panic 3.Devices were two PLDs in PLCC44 package : a ispLSI 1016 and a ispLSI 2032.
  • Namco System 11.One PLD dumped from motherboard.
  • Namco System 2.One PLD marked “SYS87B-2B” dumped from a CPU board of a Golly Ghost! boardset.This has slighly different equations than usual one marked “SYS87B-2” we had on database.
  • Quick Pick 5 , a slots game by Konami.Two secured PALs here, I reversed them into GAL16V8 fusemap.Picture of board:

  • VJ Dash1.2, a music game from Jaleco.Dumped one unsecured Xilinx XC7336 (PLCC44) PLD and one secured PEEL18CV8 (reversed by me into GAL16V8).Picture of board:


Artemio Urbina sent in dumps (from seven devices) from a Thunder Zone PCB, according to him these are specific to the Japanese ROM set so they may not work on other versions

‘chaneman’ sent in dump of a 82S153 device found on a Pengo bootleg board.He also send info on how to run on this board an unencrypted version of original Sega game code, you will find notes on database.

The user ‘undamned’ from Arcade-Projects forums dumped the PAL marked ‘D77-20’ from the Taito F3 cartridge ‘Kirameki Star Road’, device was an unsecured PALCE16V8 @IC37:

Lastly, I converted to GAL16V8 a BPROM found on a Black Tiger/Black Dragon PCB.Dump of the BPROM (a Fujitsu MB7114 marked ‘BD03’ @11K) was taken from MAME ROM set.GAL conversion was successfully tested by the Arcade-Projects user “rewrite” on his board which was missing this chip.

Thanks to all contributors.

New dump of KD29B added

Today I’ve added a new dump of the KD29B PAL from King of Dragons on CPS1.
The original dump was taken from a seemingly unlocked device but was dumped as a GAL16V8 instead of a PAL!6L8 which may have caused issues.
Anyway, I’ve recently had the opportunity to study this chip and have what I believe to be a more accurate version.

Muddymusic sent me a Dangerous Curves PCB which has a load of unlocked PALCE16V8 devices on it.
I dumped them all using my programmer.
The PCB is a non worker so I cannot test these but they are assumed working at this point.

Thanks to my good friend Muddymusic for this

Super Pacman PAL 1M update

Dec 012017

From time to time we get a message saying a PAL we have doesn’t work. Usually when this happens there is little we can do as we no longer or never did own the PCB. On this occasion however we found a resolution.
Kyle point out that the file we had for Super Pacman 1M didn’t work for him. He claimed the equations for the PAL didn’t include the use of input pins 5 and 6. To back up his words with a schematic showing then attached.
The strange thing about this is he also dumped the PAL in his programmer and got the same output file as the original dumper (Channelmaniac) did.
From here Kyle built the 27C020 adapter and bruteforced his PAL chip. This time he got something that did work.

His recreation is now available for download in place of the old one.
I have a suspicion the Topmax programmer has a little bug in the handling of PAL10L8 chips although the other dump supplied by Channelmaniac supplied does work without issues so who knows.
