a little help for a newb

[upinout]

Hey all.  I bought the new Animal Crossing game for wii, and am eager to use some of the cheat codes I've seen.

I did allow the most recent update (When I first put Animal crossing in my wii, it said it needed to do an update to run the game..)

I successfully installed the HBC, but now when I try to install Gecko OS, it says that it is not a wii application.

What am I doing wrong?

Also,if you need more help, try changing it to boot.dol instead of boot.elf.

if you ever get this error, convert it into a .dol file
