[LightGun] Desynchronization between flash and crosshair in light gun games with a black background

[toniosj]

In games like Hogan's Alley, where you can shoot at the black background of the home screen on an original NES, it works perfectly.

In the emulator using a CRT and a Guncon 2, there's a desynchronization between the flash and the sight's appearance, so the shot isn't detected.

I've attached a slow motion video for clarification.
