Finally I had some time to test this version (1.05). It looks and feels awesome, but I encountered two bugs: the first was already stated before. When I use a joystick with auto fire, that requires me to hold the button down for firing, it continues to fire even when I stop pressing the button or disable the auto fire altogether. It stops however, when I press the button without using auto fire (tested with competition pro and QuickShot QS-137F). The second bug is, that the datasette, that is usually plugged in, turns on when I start the game (I hear the motor). That's a little annoying. Maybe you find some time to look into these problems.
