Using X-Ray during frame advance

[InsaneFirebat]

The game will get stuck in an infinite loop if X-Ray is activated while using frame advance on P2 controller. The screen changes color at some point. The loop happens in the X-Ray Stage 4 routine, which takes two frames to complete under normal circumstances. More research is needed. I may look into it more in the future, but any help is welcome.
