I've tried searching the forums, but no dice. So here it goes. I currently have a Wii with 3.1U firmware modded with the original WiiKey. At this point in time I do not wish to upgrade to the WiiKey 2 or the Wiikey Fusion. A lot of games that I've downloaded recently e.g. MadWord, Dead Space etc...require a system update. What firmware is the WiiKey compatible upto? Will updating to 4.2U brick the console itself? Thank you for pointing me in the right direction. Cheers.
