I have started (another) project called SciLor's GSensor Control.
It is a software for emulation dpad input over the gsensor. Currently you can only choose between to modes:
[*]Analog Emulation - tries to emulate an analog pad by pressing the direction the more often the more you tilt your device
[*]Digital Pad - If you tilt your device to the left, the button left is hold. If you put it flat again the button is release
Happy using
