Welcome!

The Troubleshooter is a patch that allows you to use the Act Labs PC USB Light Gun or TV USB Light Gun with a number of old PC rail shooters that normally do not support these guns.

Although the Act Labs light gun functions as a mouse, several older mouse-based shooting games do not handle the mouse in a way that is compatible with the gun. They read input from the mouse in relative mode, but the light gun only works in absolute mode. (See History for a more detailed explanation.)

The Troubleshooter bridges the gap between the Act Labs light guns and these games. It also adds support for two-player games, using two light guns!

(Dual PC USB Light Guns not supported in Windows 2000.)

What This Isn't: The Troubleshooter does not fix any problems with the games themselves. If you are having difficulty running a particular game on your computer, The Troubleshooter will not help you.
