Emulated Wiimote: Fixed the angles to x, y, z values conversion. There's just one thing left to fix before the combined roll and pitch works, when roll is more than 90 pitch has to be changed from for example 15 to -165 or something like that. Until I figure that out you can use the emulated roll and pitch separately by setting the range of either one of them to zero.
