Today we have some new PAL dumps from these boards:

• Thunder Blaster (japanese release of Lethal Thunder, Irem M92 hardware).Devices were two secured PAL16L8 located on ‘M92-C-B’ ROM board.The one labeled ‘M92-C-2L-‘ @IC7 is present also on all other revision of M92 ROM boards although under different labels.The one labeled ‘M92-C-7H-‘@IC43 is specific to this game.256KB binary PAL dumps has been sent in by ‘robotype’ and I took care of reversing them.Lastly I re-organized all the IREM M92 dumps in the database adding notes about shared PALs and indication of ROM board hardware revision where they come from.

• Rabio Lepus (japanese release of Rabbit Punch, Video Systems).Two secured devices dumped and reversed : one PAL16L8  on CPU board and one EPL16P8BP on video board.

All dumps have been successfully tested back on respective PCBs using GAL16V8 targeting devices.

Today I dumped two PALs from a Big Fight and Ninja Emaki PCBs.In the first board, device was a secured PEEL18CV8 located on daughterboard @IC56, I was able to fit equations in a GAL18V10 targeting device.In the latter board, device was a secured PAL14H4 @10F on CPU board which I successfully reversed onto a GAL16V8.Both boards had also other PLD devices but all set as registered so not dumpable.

Today we have new entries in our archive.

Coolmod sent dumps from a Crime City (Taito) PCB.Devices were all unsecured (three PAL16L8 and one PALCE16V8), I took care of converting dumps to GAL16V8 fuse maps and I successfully tested them on my board.

Team Europe sent 256KB binary dump (obtained with the Charles MacDonald 27C020 PLD adapter) of the PAL16L8 from a Fun World – MegaCard MC3 PCB.I reversed equations into a GAL16V8 fuse map which is untested for now since board is not working.Thanks to both for their contribution.

Lastly,  I successfully adapted into a GAL16V8 the bipolar PROM @7A – IC52 from a Vigilante (Irem M75 hardware) PCB , you can find .JED in the archive section.
