Well, that was fast and really informative, thanks for replying
@Ibcap and
@GuyInDogSuit , I really appreciate your help.
And yes I'm only booting Atmosphere via fusee primary and I think those games were installed through XCI with SX OS in the past, I had no idea about that issue. (Edit: I've tested reinstalling those titles in their proper NSP format and now they're working just fine, case solved!)
Thanks for all the additional info
@GuyInDogSuit , I will definitely stick to Atmosphere only after fixing those installations.
