I just downloaded the games for the nostalgia aspect, but it is buggy on my PC. It seems like the up arrow and left arrow buttons are stuck. When I scroll down in the menu and stop pressing the down button, it scrolls back to the top by itself. When I start a new game he walks to the left by himself. I can make him walk right, but the moment I stop pressing the right arrow he moves left again. I play on a laptop with a wireless keyboard. I tried just on the laptop itself (keyboard unplugged) and it did the same thing. I restarted and also reinstalled. It does not do this on my brother's laptop, so the problem must be with my setup.

Any advice?
