Few months ago, in a friend's house, my friend and I tried my Singstars Mics in his Wii console. They worked perfectly! Now I have a Wii, but they don't work. He doesn't know what IOS he used. I try using Hermes v5 IOS 223 with base 37, and Waninkokos 249 with base 37. I also try with Configurable USB Loader and uLoader v5, selecting the IOS 223. What's going on then? Why they work at my friend's Wii and not in mine? Any ideas? Thanks in advance!
