Thank you , TheDaddy !
The board is original. Some time ago I got one with those two PALs missing, along with the three Sega 315-5025 custom chips, and I originally thought I would use it for parts. But then I felt sorry for it and decided to save it.
It also came with the encrypted CPU. I only tested it with an oscilloscope, and it showed signs of life, but I won’t know for sure until I power it up.
Are those two PALs from Pitfall II the same ones?

I programmed the two PALs from the link someone gave me. The PROM at position IC76 was also missing, but I added it using an adapter and a 27C512, which I programmed from the file in the MAME ROM set, pr-5317.76. I also reprogrammed the main CPU EPROM with the one from wboyu, and the board came back to life
Now I’m waiting for the board that emulates the three missing Sega 315-5025 chips to arrive. The next step is that I’d like to buy a multi-game kit from somewhere. Does anyone sell one at a reasonable price?
Best regards!
