So, I think I still didn't get it right.
I got the Gecko OS, made some new folders and put the Cloud texture in :



Than I got this codes:

GCT Code File [RSBP01 --- PAL Brawl (Unrestriced camera, disable custom stages and all codes needed for file replacement to work)

And placed it on a codes folger as described.

When i launch the game with Gecko OS it says codes loaded and stuff but if I chose Ike he still is Ike and not Cloud, lol

So, what did I do wrong? Do I have to configure something in Gecko first?
Is there something to activate the codes?
Or maybe I just placed the folders wrong?

Pls help me someone 

So, basically I just want to know how all this hacks works. I don't want to know how to make my own Hack, I just want to know how I can get the Hacks of the Brawl Vault into my Game. So I got the hacked Wii and the .iso file of SSBB.

What do I have to do next? Do I need a special loader? I just need a noob friendly explanation. Thank you
