DraStic DS emulator
I just wanted to put my 2 cents out there just in case some other members of the community or anyone who googles info about the emulator are looking for opinions about the app.
It is awesome and you should purchase it.
It runs literally all the games I've tried at full speed (pokemon, all the Mario franchise games, golden sun etc.)
The developers push updates frequently and respond to emails.
Its honestly worth the money considering how much you'd pay for an actual DS.
No links because its a paid app and that's frowned upon in our community but you can easily find it on the play store.
