Would be interested to know what kind of controllers and tools you are using for gaming.
I recently just bought a second USB Logitech dual action gamepad which lay good in my hands.Installing the drivers is so easy and works flawlessly!

Also for some DOS games i use Total Game Control.

All keyboard and mouse function keys can be placed on your gamepad
