Hello, I want to make my own Omega Ruby romhack. All I want to do is to change the music that is used when playing online. I've been using this guide https://gbatemp.net/threads/tutorial-how-to-decrypt-extract-rebuild-3ds-roms.383055/ but I still have some questions: 1) Is Braindump the only way of decrypting a CIA file that is already installed in the 3DS? Is there any faster way? (because Braindump is incredibly slow). 2) I don't care about HANS (since it's incompatible with game updates, so I wouldn't be able to play online either way). I want to repack my romhack as a CIA. The problem is, the Braindump method doesn't dump the exHeader and I need that file in order to build my romhack with 3DS Builder. What's a solution to this problem? Thank you a lot for your time and help.
