So, I made this other topic, but since the problem was kinda undiagnosed at the time and the title could be misleading, I decided to make another one. The problem is, I can't install the Homebrew Channel -- I had it uninstalled due to some bugs (WAD Manager giving me a -ret error and Snes9X GX not loading at all), and when I tried to install it again with the Twilight Hack, it failed, giving me a "loading .text.0 @ 0x80004000 (1460832 bytes)" message, or, with the old beta 9 installer instead of hackmii installer, "exception 300". I had another system menu by the time I first installed the HBC (I upgraded to 3.2U in order to play a game), so the most obvious choice would be using Bannerbomb. Problem is, the Wii seems to only recognize it if the Twilight Hack is in the SD card (otherwise it shows as a gray question mark) and, when it does work, all I get is an endless black screen, sometimes coupled with the disc drive flashing, sometimes not. I tried using that special boot.dol made to test it, and I once again got "exception 0300". I also tried, with the Twilight Hack and before trying Bannerbomb, installing the WAD Manager directly, to no avail. I found no fix for those two errors, at least none that worked to me (such as taking out GC memory cards and controllers), and I'm at lost. Could someone please help me? I really don't know what to do, and I can't play some of the newer releases such as Rune Factory Frontier and Let's Tap without Gecko OS... any help is appreciated. Thanks in advance, and sorry if I'm doing something wrong!
