I need help identifying one old anime that was about people getting trapped inside a computer.
I don't remember much about it but I remember that there was a mad scientist that put himself on purpose inside a computer. Then he was able to control the computer and somehow the computer was able to trap other people making them play games to survive. For example, I remember a scene where a man had to play a Pac-man like game and had to avoid being eaten (but he was eaten eventually).
Another thing I remember is that there was a guard dressed in a black and yellow uniform, and he was making sure that all the prisoners were behaving right. He was an African named John and while he pretended to be tough with the prisoners, he helped the main character in his attempt to escape. He was killed by the computer for that reason.
I don't even know if this was a series or just a movie, they were always showing in TV the same episode (not even the complete episode...) and I still wonder what was the outcome of this story!
It's been more than 20 years since I last saw this episode.
Any help would be appreciated!
