The Commodore 64 was famously intended to be a family computer that could also play games. The Plus/4 was intended as more of a business machine, without hardware sprites or the 64’s capable sound chip. It still had 64K of RAM though, and some productivity software included built-into the system in ROM. It could also output more colors than the C64, was clocked at a higher speed, and had a simpler design with fewer chips.

Still though, the lack of hardware sprites was a big limiter for games, which remained a driving factor for microcomputer adoption. Having no sprites, in Pac-Pac, the player’s surrogate character and the ghosts are both drawn on-screen in software, which consumes a lot of processor time. The game still runs at a decent rate though, and is fairly fun to play.

It’s best not to play Pac-Pac like Pac-Man. Despite a superficial resemblance it’s much the different game. The ghosts don’t have different personalities, and don’t coast confidently through the maze, but jitter about uncertainly, and randomly. This makes them generally easier to avoid, but it also means they’re prone to camping in the vicinity of uneaten dots. You’ll find you’ll have to lure them away from the last dots in the maze to get to them safely. You’re more likely to lose a Pac from daring their presence a little too closely.

Unlike Pac-Man there are no energizers, so there’s no way to attack the monsters yourself. On later boards the ghosts slowly get more aggressive, and they move faster. There’s also a timer to force you to go after dots. Eating randomly-appearing fruit replenishes the timer by a bit. There are also Question Mark items that appear in the maze, that can produce good or bad effects. They’re usually good though. The only ways to earn extra lives are by earning 5,000 hard-won points or, occasionally, from a Question Mark.

To play it you’ll probably need an emulator, such as the one from WinVICE. RetroArch can play it with its xplus4 core, which comes from the VICE project.

I am informed that the author of Pac-Pac, Skoro, passed away earlier this year. He made a plethora of work for the Plus/4, as shown by his page on Commodore Plus/4 World, from 2019 to all the way back in 1988. 31 years is a good long while, and I hope that the fruits of his labor will be enjoyed for decades to come.
