After a few experiments i'm a little smarter. I repaired the error 003 and so the Wii starts with the 4.3U version. Then I removed the Korean key to be on the safe side, using the IOS 236 installer so that I could use ARC 1.1b mod 06 offline ( with IOS 236 ). With this I downloaded and installed 4.1K. In addition, Priiloader v.0.9.1 and the system menu hacks are set ( e.g. region Free wii games ). No game worked. Then I tested a lot with ARC. I've always left the language in Korean. First I did the tests with Wii Sports in the PAL version. The game is only shown in the disc channel when I change the area and game settings to Europe. It looks similar with Mario Kart in the US version. Only when I change the area and game settings to USA will the game be displayed in the disc channel. So far so good, I thought, but why don't the region Free wii games work in the Priiloader?
