Hi, I am trying to remember a movie, think it's old, maybe 80s not sure. It was about a kid that had something in him that made it so he could play video games good and complete them without errors. I know it was something about that he had a friend and the friend discovered that when they played on a computer (possibly a commadore, I rememeber a joystiq being used).
Another scene I rememeber is him being captured, not knowing it, and sitting in one chair and playing like 9 different video games with his mind at the same time.

The only movie I can think of is the Wizard but it doesn't quite fit your whole description.

Possibly,.

D.A.R.Y.L.

The boy had a cybernetic brain. This allowed him to play
video games with the same reaction time as the game
Without error.

His creator knew that the military wanted to use him as a weapon
But the scientist came to see him as a son. The scientist went on
The run with Daryl to keep the military from dissecting the boy to
See how he worked, but he scientist was killed and Daryl's had
Amnesia. He was found alone and eventually put in a foster home.
No one knew of his special brain until he told his friend.

You know what I think you might be right... I totally forgot about that one! Good movie!
