Mario Kart Wii Gecko Codes, Cheats, & Hacks

Can you make a pinned thread about the Flashhax method of getting Wiimmfi, via chadsotft.co.uk/wiimmfi? Would be useful for anyone who found this thread and want to play on Wiimmfi but got no SD card.

I have never done the Flashhax exploit, so me writing a tutorial for it wouldn't make sense. If you have done the exploit yourself multiple times with consistent results, feel free a write a tutorial in the Guides sub-forum.
