and it can install korean support on your wii, which is then overwritten if you install cIOScorp...
PS: korean disc support does not break wad installs in the ARC mod05, just checked.
that problem existed when you could install IOS249 for korean discs, also by qleap, and was only a problem with wad managers that used 249 (1.2+), wad manager 1.1 still installs wads fine with that cIOS, as well as with ARC mod05 fully installed.
...but cIOScorp still overwrites it, unless someone wants to fix that in cIOScorp.
korean games are signed with a different encryption key from the rest of the world, which means they will actually freeze the wii as the structure is recognized but the disc cant be read on any wii without the key...korean wii's have both keys, all other wiis only have the non-korean key.
Dack made an app, gave me a beta, and it successfully (and easily) resigned a kor game with the regular key, so special things like qleaps stuff wouldnt be needed, but he seems to maybe have forgotten he wanted to release it? lol.
