Got 2 more PAL dumps from the M92 range, this time from a Hook PCB.
We are not sure if the ROM board PALs are game specific so they are listed under the general M92 header.
Thanks to caius and robotype for these PAL dumps
Another one of muddymusic’s PCB’s.
Everything looks fine with this one until it is coined up then the game starts automatically.
If I enabled test mode by switching switch 3 on DSWA then I could see the start button for Player 1 was stuck on.
I initially thought this was going to be a sticking point as all the inputs go to a custom chip however I found that the trace from the pull up resistor array to the custom was broken somewhere.
There were no visible breaks so it must be under the silkscreen somewhere.
Running a patch wire from pin 2 of the custom chip to the resistor array fixed the issue.
Quite a fun game it is too.
Got muddymusic’s Vendetta PCB. Game seems to play fine but the blue colour is missing.
Schematics are available for this game which made it simple to find the fault.
I could see all the inputs to the custom 052535 chip but the output of the SIL was constantly low.
I have a scrap Konami PCB that uses these so removed on and fitted it.
Board is now fixed
sukhbir on the UK-VAC forums recently had an issue with my IOC1 dump.
We eventually discovered an issue and also found a PAL chip that was actually unlocked so now we have the actual dump of the chip (and its quite surprising how it works too).
Best submit this to MAME too.
My good friend muddymusic has made his debut in the PAL dumping world and has sent some PALs from the follwoing games:
Athena
Bank Panic
CPS1 Nemo
CPS1 Strider
Rohga
Secret Agent
TumblePop
Obviously and registered devices were not dumped but this is a great list.
Thanks to muddymusic
