Make sure you're using these patches and the latest version of Atmosphere:Sup guys,
Updated my atmospshere the other day to the lastest version. Only thing is all my games work except animal crossing. does anyone know any possibnle reason as to why it doesnt load? It hangs on the switch screen then says error loading then that's it. Game was working fine before that

Also, make sure you are booting using the latest fusee-primary.
