Description: GreenLightHack is a HackMaster hack that will invert your screen when the backlight comes on. It was designed for the PalmPilot Personal/Pro and Palm III to make them look more like their newer cousins (the Palm IIIx and the Palm V). It is possible (untested) that it will have the opposite effect on the Palm IIIx and Palm V. This hack is free. It saves you green.
