if what your saying is right in regards to everyone using the public headers, am I able to put one of my headers from a completely separate 3ds game (lets say Mario kart) and put that header on my Pokemon OR Rom that I use on my Sky3ds??
Thanks =]
specialized info regarding your concerns should be someone here:

(I may not be of much help, since I am actually playing my own backups.
and whatever roms that aren't my backups, are all CIAs)
