After repairing it (see log here) I dumped the two PALs from an original Seibu Raiden II (set 4, Italy revision) PCB.One dump is tested and working on a GAL16V8 replacement.The other one was good apparently but when I  tried it  on the PCB I got sprite issues.The original device is a PEEL18CV8 and it seems that it has been programmed as registered (PIN1 is tied to a 16MHz clock signal) so we can’t do much about for now.So, this is a partial set.
