I cannot find a way to change the settings so I can chage teh screen resolution. Right now it is so tiny the game is unplayable.

This is a dosbox game.
key combination: ALT + Enter

Keep in mind that this is an old game. Back then almost every game used a fixed resolution to prevent taxing the CPU too much. ALT + Enter will fill up the screen but it will also make the pixels bigger. There's nothing to be done about that short of a high-res remake.

I'm having issues also, I cant play the game because some of the text and things are off screen. The size is not right and I dont see how to change it anywhere. It is fullscreen but not using the full screen.
