Fixed it! So yes, technically the problem is resolved now. However, it took about 3 hours of my life to figure out what went wrong. I figure I can help save other people a headache if they run into a similar problem. Anyways, here's how I resolved it: Problem: Unable to run the latest bannerbomb or smashstack. Specific games (Brawl and MKart Wii) don't load. Homebrew dissapeared.by dchain - FixMii
To provide some context before the problem: I was running 4.1U and was following the basic bannerbomb process. BootMii installed fine, as well as HBC. I restarted the Wii, and BootMii was there. I figured everything was fine and went to load a game...black screen (frozen). I restarted the Wii and BootMii didn't appear, but the console booted up as normal. Tried HBC...black screen.
