wads wont fuck up your wii unless you install wads from other regions than it may or may not brick, or they simply wont work. however the ios wads they can be dangerous
wads of all shapes and sizes can cause problems with your wii
bad IOS (sys) wads (which are actually very rare) will cause a FS problem (usually they just won't install)
~if this happens, bad bad brick, but sometime fixable by same method
bad "Channel" wads (can cause banner brick or alternatively a semi-brick)
~most common, use 3.2 + Starfall + TP-hack and no worries
bad hidden channel (never seen this happen) should just cause the desired function to not work
QUOTE(kedest @ Nov 20 2008, 06:46 AM) How brickproof is such a solution? I've never before installed wads because I was worried it might go wrong.
Can starfall's rescue menu patch + booting the wad manager through twilight hack solve every wad brick?
