Papilio user and longtime Papilio arcade contributer Alex has managed to get the Pengo game running on his Papilio Pro board.
Here is a quick demo video of the game running on the Papilio Pro:
Alex writes, “The Pengo hardware is very close to the Pacman hardware but annoyingly it has just enough differences that you can’t just run Pengo on Pacman hardware. The video, sound, input control registers, watchdog, etc are all at different addresses compared to Pacman as well as the fact that the ROM is twice as big as Pacman’s and to make matters worse the Pengo ROM is scrambled, so I had to implement an on the fly ROM descrambler based on the MAME source code.”
Thanks for sharing your work with us Alex!
