I believe this is possible, and I'm not sure where should I start to check. I would like a plugin to put a picture on the back of the game to replace the black bars. My games have a fixed resolution, so I would like to make some "arcade cabinet" art or things like that to put behind the game if the player wants to use fullscreen for some reason. If you don't have the time to make a plugin like this, but know where in the original code this could be performed, I can work it myself. Thanks in advance, and I hope you are having a beautiful day.
