Wild West Shootout arcade play with the sinden lightgun

I've just saw ending of this game using latest demul shooter V10.7.0. All functions include crosshair on/off option and auto fire works well. But there a graphical glitch after the bonus stage.
The saloon doors' graphic do not disappear after the bonus stage. The door still remains and disturb my sight until the ending.

PS ) I found this glitch only happens at 3840x2160 graphic setting.


Here's my AHK script. You should change the path section whre your files are.
