I don't completely know what I'm doing so hopefully someone could help me out here. This is the root of the card. The "3ds" folder has all of the following. Are there any that I need to keep? The only thing here I use is "ctr-httpwn" to bypass firmware updates. I don't use any other homebrew from here except that ROMs folder. Can I just delete the rest? And finally, the "files9" folder. What do I need to keep from here? Any help would be appreciated.
