Time Crisis 4 Gun Won't Change Screens During Multi Screen Battles #1256

Time Crisis 4 has Multi Screen Battle segments where you have to aim the gun to the left or right to change. The screens won't change if you aim to the left or right.

I myself eventually figured out you have to press the screen out button while the gun cursor is far left/right (or approaching left/right). I recall screen out is binded to one of the dpad buttons by default.

I guess the screen out button should be "pressed" automatically when the gun is out of the screen though? I'll have to implement that.

On h/w, the screen out button is binded to the gun I/O board. The gun I/O board (CPU that is) is programmed if the sensors reach a high enough value in the x or y axis, it thinks the gun is "out of screen" and sends a signal to the JVS board through an I/O bit (the screen out button). That's the best I can explain this from working on arcade games that use this gun IR system like Ghost Squad.

Gotcha, thanks for the explanation!
