These included Tomb Raider II , Quake , and a number of others. In order to use a keyset you simply import it into the keyset manager and then point at the executable file for the game. Whenever the game launches, the Xterminator automatically gets the proper keyset loaded. This bit of magic is accomplished by a small program that runs when Windows 95 starts up. And it works quite nicely.
Programming is simple.
You double click on the button you want to program and then type the keys that should be sent when that button is pressed. You can also program in short delays as well as different actions on both the press and release of a key. While I am not about to give up my racing wheel and joystick, for those that can afford only a single controller the Xterminator makes a pretty convincing case for being that one, and it beats any game pad I've ever used hands down. While it can't outperform a complete set of custom controllers, the Xterminator may well be your best bet if you can afford only one. The programming utility allows you to assign keystrokes to the buttons on the game pad.
