Xbox modchips ran an illegal bios that could be detected. The wii modchips are drive mod chips and don't run an illegal bios. They are hard if not impossible to detect.


Xbox's were detectable for two reasons - the bios was different, and the hard drive was usually different, hence the need for the switch.
The wii mod cannot be detected. Advanced region free will be nothing more than more handshake faking between the dvd drive and the main cpu.


The Xbox updates havn't bricked modded systems, they just make attempts to break mod chips.

Any modchip can have an on/off switch...simply place a switch between the ground wires and you have a switch.
