Hello.. I have a problem.. the game runs fine in terms of speed but for some reason it's as if the right arrow on the keyboard were constantly pressed.. everything keeps going right in menus and also does the ship during gameplay.. the only section where this doesn't happen is the jukebox.. I don't understand what could be the cause.. :s
This might be posted way, way, too late, but your issue is that the cycles are too high. Game speed might be fine but if you have the cycles set to max the joystick goes nuts. When I ran this game in DOSBOX I always used fixed cycles.
