Can someone explain how I get the DLC paths to work? I have a copy of US Birthright, and I've gotten that to work, but I have no idea how to get the DLC paths to work. I've already dumped the roms for them, but I don't know how to get the randomized paths into the game. Something about making an installable CIA, but I really don't understand how to use ctrtool either. Can anyone help me?
