Here are the dumps from an original Taito Master of Weapon PCB.All dumps were obtained from three unsecured devices (PAL16L8) and then converted to GAL16V8 fuse map.All of them are tested and working.Repair log of this PCB will follow soon.
cmonkey has fixed the checksums for the Golden Axe (317-0110) set so the self test should now pass.
Thanks to cmonkey, greatly appreciated.
Shou has confirmed the operation of this decrypted set.
Thanks again to Shou
I have dumped the two PAL16L8’s from The Simpsons PCB.
The PCB is a non worker right now so I cannot test them so if anyone out there in internet land can test these I would be grateful.
Got a mammoth box of boards from Ben76 the other day. This Star Jacker PCB is one of them.
Game gave a black screen when powered up and there was no sync signal.
Ben also gave me a scan of the schematics for this board so was quickly able to determine where the sync came from.
My heart sank a little bit as the sync comes from a PAL16R4 chip
On investigating I found the VCC pin was not making a good contact in the socket so I removed both of the PAL sockets and replaced them.
So booting now gave me sync but solid white screen. Ive seen this before on quite a few boards and its almost been RAM issues. I started probing the RAM chips and found a 2016 SRAM at location IC151 had completely dead outputs despite being enabled and having active inputs. I desoldered it and replaced it with a 6116 SRAM chip.
Now I get this (NOTE: the red colour is actually present but I have to edit my pictures these days as the HTC One makes low light pictures all purple)
All fully working again.
