Add a cursor on light gun games

[KiethSomataw99]

I wonder if for light gun games including The Lost World, I'd like to see a cursor that show where the player is pointing if the mouse is used. This feature was used in the model 2 emulator and the cursor makes it much easier to aim and play the game. I also wonder how you are doing on making an interface to make Supermodel more accessible.

There is a cursor already.
