Hello, I installed the homebrew channel on my wii (which is running firmware version 4.1u). I have looked through some guides, but I am little bit confused. I am wondering if someone could answer the following questions for me: 1.) Is it possible to install an ISO loader that runs on 4.1u? 2.) Is it possible to downgrade 4.1u to 3.2u (I heard that 3.2u is the best for homebrew)? If so, what tools\guides should I use to do this? 3.) Are there any precautions that I should take? 4.) What is an IOS? 5.) What is a cIOS? 6.) What is a NAND? 7.) Is there any other helpful information that you could provide me? Any help would be appreciated. Thank you.
