Citra is a
work-in-progress emulator for the Nintendo 3DS.
What can it do?
It can currently emulate
ctrulib-built homebrew programs, such as
Smealum's port of Yeti3D.
Citra is also beginning to run some commercial games, but
all are very broken and unplayable.
Can I play <insert retail game here>?
In nice, bold letters:
No! Citra is not ready yet!. You can
not play Pokémon, Super Mario Bros., or any of your other favorite 3DS games yet.
If you check back in a year or two, this may no longer be the case.
