Playing pirated wii games?

I am only 14, and I recently bought pirated wii games in Indonesia. I have an original, authentic wii console from Australia. I have been sent a soft mod link, but since I downloaded ver. 4.3 before I bought the games it won't work. I went to a youtube video, but one of the download websites contained malware. Does anyone have a SAFE, EASY, FREE and RELIABLE tutorial for me? I understand that I need to get the Homebrew channel but I still am unsure how to do so. Can anyone please help?
