Just some issues- your system menu is still 3.3k (fail)
Try to get a full report from CB2_BB_SysCheck_1.6.1.zip
or scan your wii with Dop-Mii_v12_CB2_BB2.zip
It may not like your card for some reason, so format it with sdfv2003.exe, and if that fails you probably need to try another card.
You probably have a ios issue if these apps are loading black.
Also don't change anything in arc, you can post your current settings here though. You need to use a mod that supports korean wiis
Do this- load CB2_BB_Wad-Manager-1.4.zip from HBC, then list what ios you can choose. Use the wiimote to change the number, list all that you see.
