Hmm, interesting. I haven't seen the movie, but the imdb page says, they made a deal with Midway and had license to use pacman, super pacman and the at the time of shooting unreleased satans hollow. Source.
I did a reverse image search on your screenshot and it came up with Streaking (by Shoji). This looks like the game in your screenshot.
The arcadecinema page of Streaking says this:
In the movie Joy Sticks, an apparent clone of Streaking (credited to
Computer Kinetics Corporation) is played in several scenes, and is
referred to as "Strip Video" (or "Stripper Video Game" in the
credits).
Since I'd seen Joy Sticks prior to Streaking being added to MAME, I
was shocked when the game showed up on the MAME WIP page. I had no
idea it existed beyond the movie. Given the little information that's
available about the game, it's unlikely that it was ever widely
distributed.
There are several apparent differences in "Strip Video". The player
can be either male or female. The character starts out clothed, and
loses clothes as the game progresses (as do the characters in the
movie). The gameplay also seems considerably faster, and there is no
Fatigue meter, both of which would have helped Streaking considerably.
Finally, the color palette is different, but this could be attributed
to an incomplete MAME driver.
So, apparently this is an early erotic game in a pacman style and it was forked and improved specifically for this movie.
