does anyone know if this works on 4.2e the nintendo update as stupidly updated 4.2 before coming across this forum as i have the wiikey 1 chip and never needed to use the HBC but did have it installed before hand.

Reason im asking is i need to access the NTSC shop for GH and they all say chance the shop settings to NTSC to get the patch working and didnt want to risk the brick if it dont work. the wii is a Gen1 console so if anyone knows any guides or advice on this matter that would be great.
