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.
Dangerous Curves PALs added
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
1941 : Counter Attack (Japan) PAL dump added
We have a new CPS1 PAL dump from the japanese release of 1941 : Counter Attack.PAL was a secured PAL16L8 located @1A on the ‘89625B-1’ B-BOARD.Dump has been successfully tested back on a GAL16V8 targeting device.Thanks to ‘robotype’ for loaning the board.
Super Pacman PAL 1M update
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.
Contra and Pac-Eight PAL dumps added
Today we have new PAL dumps :
- Contra.
‘coolmod’ sent in 256KB binary dump of the secured PAL16L8 from an original Contra PCB, I took care of reversing it in a GAL16V8 fuse map that he successfully tested on board.This dump replace the old archive we had.Thanks to him.
- Pac-Eight (a Namco Medal Game)
PLDs (all GAL16V8) have been dumped by Rod_Wod of Dumping Union mailing list from this board:
We mark them as ‘assumed working’ since they have been obtained from unsecured devices.Thanks to him.
