How do you hack brawl with homebrew?

Install the homebrew channel using the method of your choice (Smash Stack, Twilight hack, bannerbomb) There will be instructions on how to use the program. For bannerbomb, for instance, find the correct version depending on your system menu version, then follow the instructions with the file here (http://bootmii.org/download/) placed in the root of the sd card. Run the installer/get the homebrew channel. Find the program Gecko OS. The most current version is Gecko 1.9.3. Place it in the folder "apps" in the root of your sd card so it looks like X: apps/gecko193 and inside there'll be three files. Then find a gct file with codes you would like to use. This can be created using the codemanager application found at http://wiird.l0nk.org/ocarina.zip. If you find a file called gameconfig.txt you can use more than 256 lines of code. I would also recommend you check out brawlplus.net and kc-mm.com. The first is a brawl hacking community and the latter is a texture hacking community, both with tutorials on how to do them. In the first, you can find a premade sd card pack. If you use that, which I would recommend, all you have to do is install the homebrew channel and Gecko.
