Some days ago ‘Palindrome’ created by hand the missing ‘VA63B’ PAL dump from Varth: Operation Thunderstorm (USA 920612) CPS1 board and Tafoid submitted it to MAME source.Today Tafoid gave me permission to add it to our database.As said, this is not the real dump from PAL device but a manual recreation of its equations.Anyway Palindrome tested it and reported it as working on his board.Thanks to Tafoid and Palindrome.
UPDATE
I can confirm the PAL is 100% working since I succesfully tested it in my Varth converted PCB.
