What are you booting Atmos with, which sig patches did you use, what fw are you using, what installer are you using?

Are you on 9.2.0 with AMS 10.5? If not that may be the issue, you need the right FW alongside the patches to play certain games.

What firmware does Animal crossing require?

edit: I checked for you:

Required firmware Yes (on 9.2.0, Atmosphere 0.10.5)
