I tried googleing it, found out its one of those titles that doesnt run yet on it.
Not all games run on it atm, they have a compatability list for it :  https://citra-emu.org/game/

Theres like ~140+ games that run well on it though, and are playable from start to finish on citra (according to the site).

update:

"We've been tinkering away, and now Citra's all the faster for it! You should see a modest speedup, anywhere from 3 to 8 percent, in the most recent Nightly build and in the latest Canary's CPU mode."

Its now another 3-8% faster than the last Hardware Renderer update it recieved.
It might not sound like alot, but it helps if your pc isnt the fastest thing in the world.

^ just go to the pick up the latest Canary build and enjoy.

Here's hoping for even more gains.

Of the games Ive tested, only one that actually had a speed issue, was Paper Mario Sticker Star.

Its more likely that you ll run into a game, that wont be playable at all, than one that needs to run faster at this point.
Dispite most games running perfectly well, and the majority of games do run, there are some that just dont atm.

Wow, it looks great.

How would you rather play ur Pokemon ?

I agree though, Citra does make some 3DS games look rather good.

Wow, the Super Mario 3D land one is SUPER impressive. Looks like a Wii game.

Well, I would probably play it with the former since I have a Switch, but I really would like it to look like the latter!
