I’m playing the game and i found out it has dlc but i have no idea if you can download it using citra or maybe patch it (if that’s even possible) so yeah i hope i’m not breaking any rules i just want to know
Not easily. The ideal way to use DLC in Citra would be to dump the DLC CIA from your 3DS, and then install the CIA from Citra’s UI. Right now though, after following those steps, the game does not detect the DLC. You can manually patch the DLC into the original ROM, but it’s a pretty complex system with a lot that can go wrong. If you’re still interested in going that route, rebuilding ROMs is beyond the scope of this forum, so a better place to look might be GBATemp.
