Which application is the Mario Kart Hack found on?

Ok, I think I have the codes sorted out, they're ready and waiting to be put in the right place. Is this also in the "apps" folder? What I really need now are instructions on how to get Ocarina or Gecko or whatever on the Homebrew Channel, especially one that works on my 3.4 version. Then we can work from there. I really appreciate you guys essentially spoon feeding me instructions, I don't think I could stand me if I were you.

Does Gecko OS show up in the Homebrew Channel?
If it does and says invalid application, you need to find it as a .dol file
If it doesn't, you need an apps folder on the root of the SD card and inside the apps folder is a Gecko OS folder, and inside that is the boot.dol

the codes go in the codes folder on the root of the SD card

Wonderful! The Gecko OS now works! It said no code was found, although I put a code in an application called codes. Perhaps I messed it up. I'll check it again. Ohh I can taste it!

Here is my code. When I go to "Launch Game" on the Gecko OS, it says so codes found on SD.

I have put in bold what has been replaced. All the 09s are replacing XX and the longer code in bold is replacing all As. I've tried both GC Controller methods. Maybe there is something simple I'm doing wrong? Thank you.

Are the codes in the .gct file?
the gct file should just be in the 'codes' folder

yeah weird right? I suppose I'll just mess around with it for a while until it works.
