Not saying that he has one, but he has many others so he's certainly worth a try.

Hi. If you have no luck with this post back and I'll try dumping it for you. From a quick look it seems as though it's probably doing some address decoding so it ought to be a reversible type.

cheers

thanks trmatthe, that will be such a big help if you can dump it.

the board works but the graphic are a mess .

That chip isnt a PAL chip but a CK2605 which is a cut down PLS153 used by Sega.
That said it looks to be easily compiled for a GAL16V8.
You have PM
