Some time in 2010-2011, I tried installing The HomeBrew Channel on a 2007 Wii. Unfortunately, it failed and now my disc can barely be read unless I keep putting the disc in and out. The Wii was in version 4.3... Did it not install because of the SD card I used? Judging from my memory, it was a 256MB SD Card. I might try again on a different Wii, considering I have another one. (Yes they're both the same model and the broken disc one still works)
