Well if motioninjoy does this, AND that, maybe use it instead?
sounds like a great driver.

Seriously though, I've never seen motionjoy do motion controls while acting as an Xbox controller at the same time. The two act as two seperate modes. Xbox 360 controller mode does just that: act like a Xbox 360 controller. The other mode is specifically play station 3 controller mode, which does motion as well as regular button input, but in that mode it is not seen as an Xbox 360 controller. Alot of games would have to be manually configured, and Scarlet's driver is nice not only for its stability and no extra bullcrap and headaches that came with motioninjoy (serious scarlet, THANK YOU for this), but the convenience. I get wanting to add the extra funcionality, but scarlet has stated already several times that he has no current interest in motion controls.
The other thing is that because of the way Xbox controller mode works, if it is possible to add motion controls on top of Xbox controller support, it would require the motion controls to be seen as another controller input, the same as plugging in an extra controller. While SOME programs/emulators can be customized to see this, alot of PC games are designed to only see 1 controller at a time, and as such would not see both inputs from Xbox mode AND Motion controls.
Seriously, be thankful for what we got.
