If your wii is already hacked, you should have a SD card with everything on it, and there should be a folder labeled "private". In the private folder, make a folder labeled "wii" and in the wii folder make another folder labeled "app" and so on, until you have the folders like this: private>wii>app>RSBE>pf>fighter. Then in the fighter folder you need all the names of the characters, make sure the folders are all spelled exactly like this:
So for Captain Falcon you would name the folder falcon, for Diddy Kong you would name it diddy, and so on. After that, download the character textures you want from here and put them in the folder of the character you want to replace. They should be named correctly, but if they're not, here's how to name them:
So if you had a texture for Yoshi, and you wanted to put it over his blue costume, you would rename the file you downloaded to FitYoshi03. Basically just write Fit(character name, use the name from the file, like captain or diddy) and then the 2-digit number of the costume you want to replace. Also, you need the file patch code for anything to work, which is this:
You'll have to convert the codes to .gct for them to work, or to add them in Brawlbox, however I can't use Brawlbox on a Mac so I don't know how to do it that way, but I'm sure there are a lot of tutorials online. Basically after you have the codes file, which should be titled "RSBE01.gct", you should already have a folder in your SD card called "codes", just put it in there and it should work. That's all you have to do for textures, but if the texture you downloaded has a PSA, there should be other files with it like "FitYoshiMotionEct" or something, just make sure they're labeled correctly and put them in the folder of the character. After you're done with everything, put the SD card in your Wii and load Gecko, and everything should be there.
I think that's it, if you have any questions feel free to ask me, I know it can be a bit confusing XD
