None are listed on Wikipedia. I'm not talking about pinball games with a Flash Gordon theme; I've seen those. I mean a game where you get to be Flash, or ally with him, or be on his team or something.
The Flash Gordon video game was created for the Atari 2600 in 1983 by 20th Century Fox games.
Loosely (and I do mean loosely) based on the 1980 Flash Gordon film starring Sam J. JOnes, Timothy Dalton and Max Von Sydow, with the movie soundtrack by Queen.
The gameplay which looks suspiciously like the better known game Defender consists of moving through a mini map maze and defeating 8 bit enemies who flash and mostly die. The player also has to rescue men from each area of the map. (Just like Defender...)
