Pete Brown blogged about changes he applied to the Silverlight C64 Emulator that allowed him to use the accelerometer as a joystick.
My primary development machine at home is still (gasp!) running the 32 bit version of Windows 7. I just haven’t gotten around to paving it to upgrade to 64 bit. My other machines, including my presentation laptop, are all running 64 bit.
Prior to PDC, I had made some significant changes to the Silverlight C64 emulator. I added sound, started to add a touch-enabled user interface, fixed up some minor perf issues etc. One of the changes was to enable access to the Windows 7 device API in order to use the accelerometer as a joystick.
