I've successfully installed the SuperCIC mod in my SNES, works great, check this forum topic for more info. Brief introduction: SuperCIC by ikari_01 uses a PIC16F630 circuit to cleverly utilize the SNES reset button as a PAL/NTSC switch (no external switch needed) and it replaces the original CIC effectively disabling region protection, it also drives a 'DUO-LED' (replacement for SNES red power LED) to display current region mode."
