I tried doing that, but it says the file is too big and that it isn't a folder. Does the file need to be in a certain format to work? I have a cia, sooooo...

Where do you even get the files to uncompress?

I want to swap models, switch icons and splash screens, and even alter cutscenes. Could I get some help and advice on what to do and what software to use?
