Since Nintendo originally designed the Wiimote as an accessory for the Wii, not the PC, it's been stop-and-go getting Wiimotes to work with PCs using a variety of drivers and what-not. v2.5 of Carl Kenner's GlovePIE incorporates the following changes to getting the Wiimote on a PC to act like a Wiimote (albeit on a PC):

• WiimoteScripts folder
• Wiimote battery level
• Wiimote normalized gx, gy, gz force values (0=none, 1=gravity)
• Wiimote pitch, roll, and rotation matrix, seperate from movement
• Wiimote raw accelerations in m/s/s with gravity
• Wiimote relative accelerations without gravity
• Calibrate Wiimote manually, or use Wiimote's own built in settings
• Access BlueSoleil window from CP-Settings > BlueTooth menu
• Extract Miis from Wiimote (From File menu)
• MIDI no longer gives error if no input device
• Various other bugs fixed, and new bugs introduced
