Nvidia users are recommended to build the cache with assembly shaders enabled, then once the cache is done or big enough, disable assembly shaders to get a smooth experience. For a faster way to build your shader cache, do CPU matches keeping this in mind. The game uses two different sets of shaders, one is for to 1-4 players, second one is for 5-8 players.
This game is very shader intensive, when you first play this game stutters frequently to cache shaders.You cannot play local wireless and online as it is not implemented on yuzu.The spirit board also is problematic and will likely look like it is continuously shuffling.To remedy this most times just restart the emulator - emulation until the issue is resolved. Some modes like Spirits Adventure Mode will trigger crash or when a battle start most times the screen will stay black but audio will typically still play.You will require a firmware dump to play Mii levels. But some modes are unplayable as the services required by them is not implemented. The below game entry is based on user submitted content.
