Hey Link, I noticed this one can be reduced a step:
Solution B:
-get the MIOS from the Super Mario Galaxy/Mario Kart Wii/Smash Bros Brawl disc
-use it to run a new Action Replay
-use its freeloader to run an old Action Replay
-use SD Load (see
http://www.gc-linux.org/wiki/SDload )
-run Gecko OS 1.06d Gamecube edition with it - WIiRd will be able to communicate, just do not use MEM2 addresses
-profit
You won't need an old AR as well, if you have a new one and an SD Gecko[which you need for this solution anyway]
You can put the Gecko OS dol on the SD card root or in a folder, insert the SD Gecko and New AR, load AR, it acts like an SD Loader-
it comes up with a screen where you can select an app, kinda like SDLoad
