The flickering in pac man 2600 makes it unplayable 5200 version is much better to see with improved graphics. 2600 baseball also has flicker. And 2600 basketball also compared to nes or snes versions not as good. The tiny ball and stick figures and no line on the court. Pong is fairly simple just a ball and 2 paddles. Not much to see or do. Just pass the ball back and fourth. I just see 2 purple sticks here. I can't even make out the net vs the pole if I did not watch it. Nes version art least I can clearly see the hoop
It is much clearer here which is the pole and where the net is.
