Hacking Private header...

[Tellmee]

I recently started using Gateway and have a question.
I have my own private header dumped from my MH4U retail cartridge and have been using the header for my other roms.
My question is that Do I need to use private headers to even SINGLE PLAYER only games such as zelda or metal gear solid 3D?
I just want to know if it is ok to run single player game roms as it is or if I have to apply private headers to all my roms.

Headers are only used in online play, so they should be fine in single player games. If you're paranoid though, play them with wifi turned off.
