You can use this to run ROMs from flashcard. That includes Pokémon.
Sadly, the mainstream Pokémon games don't work yet from SD card. Only Pokémon Trozei/Link and the Mystery Dungeon games work from SD card.
The backend of TWLoader which does the SD ROM loading, known as nds-bootstrap (developed by ahezard), will be worked on again soon.
The Mystery Dungeon series stutters so badly that it's literally unplayable (for me). It's smooth sometimes, but it like stutters like crazy. I can't think of anyone who's sane enough to run the game at that state. Hopefully the next version improves. Btw, I'm on a n3DS 11.3, using L2 + Clock. Still stutters.
