Xbox 360:Lightshow

File:Lightshow v1.7z (source) is an app created by User:Derf that allows you to test the individual LEDs on your Xbox 360's Ring of Light (ROL) as well as the center power LED. Credit to landaire for smc.h and smc.cpp.

Usage

Hold the Left Stick in the direction of the LED you'd like to modify and press a button to change the color to green, yellow, red, or off.

Press Start to toggle the center LED on or off.

If all ROL LEDs are set to off, the system will turn Player 1's LED to green. This is a feature of the system, and cannot be overridden by the app.
