Version 0.6 now has virtual gamepad emulation, this means you can use DS2Key with any application requiring a joystick/gamepad.
When in gamepad mode the touch screen is used as a analog stick, which resets to the center when not being pressed (similar to any other joystick).
Currently the gamepad mode only works for a single person, but key modes MIGHT function properly for other people at the same time.
You must install a external program (PPJoy) to make use of the gamepad mode functions, I've included the instructions on how to do so in the archive.
Also I included a simple configuration application that runs in text mode, its still a little confusing but it should be easier then just manual editing.
If anyone has problems with DS2Key or wants to suggest something or anything else reply here or contact me by email or something .
