Is there a way, to install the DLC or play them using Citra ?
DLCs can be dumped with GodMode9 as standard CIAs and installed with Citra though there is an issue with it not being detected by games.
So, would the DLC content be playable or not using Citra ?
Not at the moment, no.
Aww That kinda sucks, but oh well, will it hopefully be a goal in the future ?
Honestly the guy who’s worked on update support and CIA installation doesn’t know why it doesn’t work already.
Oh! That’s not good news but oh well, can’t complain, citra is an amazing emulator, hopefully it could be solved in the future.
