I have a original launch Wii that I installed has 4.1U firmware on it I installed the Homebrew channel a few years ago. However now My Super Mario Wii, original disc which I bought, will sometimes freeze on me give me a black screen after playing awhile. Any idea whats causing this. I didn't update to 4.2 or 4.3 because it would delete the homebrew channel. Also my shop channel doesn't seem to work.
