Hack my Pac: 4-in-1 Pac-Man Menu

When I bought my above average Pac-Man cabinet, I wondered if there was a way to choose between playing Pac-Man or Ms. Pac-Man. My wife said she wanted to play Ms. Pac-Man with the fast mode enabled.

Of course I first ran across the 96-in-1 Multipac. But why in the world would you want to have 500 variations on Pac-Man (plus Pengo)??? Ok, Pengo would be cool, but I don’t want to play “Pac Electric Cowboy”, or “Pac Mr. Roboto”!

image001Thankfully I found Jason Souza’s 4-in-1 Pac Hack. WOW! This is exactly what I wanted. No more, no less.

Before I could install the 4-in-1 Pac-Man multigame, I had to get the Pac-Man operational. (Note to self: make sure daughter boards are not upside down on day 1!) Since I was already ordering parts from Bob Roberts, I asked him to include the supplies to install this hack. Not including shipping, it cost me $26.50 for the two ROMs, ROM programming, ROM sockets, and wire. So, after flipping the Z80 Buss Sync Controller, replacing 2 RAM chips, and replacing the sound transistor, we were ready for the hack.

Two months pass… while I am waiting on parts for my Space Station Pinball repair I decide it is time to hack my pac. 🙂

It was very tedious, and at times difficult to solder the tiny wires to the chip legs. And then there was the worry that I would connect things up wrong, so I quadruple checked every wire. I even used a continuity checker to ensure none of the legs I soldered were accidentally shorted to the leg next to it (there were a couple of those that needed to be corrected).

I am almost embarrassed to share this with you… it looks like my pac board got attacked by a spaghetti monster. But the end result was worth it. 🙂
