I saw a youtube video where hyrule warriors is playable and its an unofficial build, but sadly the devs of that stop supporting it… so will hyrule warriors become playable??
You can find better help with that from whomever created that specific build.
look for unofficial citra builds forums, there is one on gbatemp.
Then you’ll need to bug them. There is already a open issue for this game. If the fix was already that simple it would have been merged but it is very likely a hack. Will the game become playable, eventually yes. Obviously the point of Citra is to accurately emulate all 3DS games.
