Hello everyone, this won't be much of a repair article but stay with me. This game is Konami's Boot Camp. Actually this name is the name published in America – in Europe we know this game as Combat School. It is one of my favorite games. I thought it was the same between regions and bought the USA version, but there was a difference – the American version is played with a trackball, not a joystick. I will convert my board to play with a joystick at some point.
Here is the board I received:

The board was sold to me in "working" condition, but when it arrived I encountered a problem. At first, the RAM & ROM Startup Tests pass successfully: and the title screen appears as it should:

But along the top edges of the title logo and inside the game itself, there is random pixel corruption everywhere. The circled pixels on the flagpole shouldn't be there.
