I'd just have a go at installing the Homebrew Channel cos it was so easy. I found a unused 2gb SD card in a Digital photo frame on our fireplace and off I went. 20 mins later im play Super Mario!!
First time I'd bothered with HBC etc so I had to install all of that which took about 20 mins. I had the following:
PAL Wii 3.4E with Wiinja deluxe
I installed Neogamma R8 Beta 7 and it loaded up fine.
Just working my way through World 1 now
