He said he copied the files from the rar; you have to extract the rar before you can open it. At least on my computer anyways.

I downloaded the No Heart one just to look at the file layout.
When you put it into your SD card, I assume you placed the FitGanon files and whatnot directly in the /ganon folder.
Since it's named FitGanon03, it replaces the blue costume. However, you have to manually insert the portrait into the common5 file if you want the modified picture to show up on the selection screen; however, without it, the hack should still work, it just won't have the modified portrait for the Character Selection Screen (CSS).
Did you place the files properly, and check the blue costume slot? If you did, and it's not working, I'm not really sure what the problem could be.
well, i feel like an idiot now. No Heart worked, thank you. And for PuToTyra, i forgot to rename the files from "fitganon00putotyrano" to "fitganon00". Again, thank you for taking your time to help me. sorry about my stupidity.
