I mean it does everything really, mp3 player, GPS, Internet, compass (maps), communication even games. That said I am a little disappointed because they have been removing things like headphone Jack’s, Sd cards and I really thought at this point we would all have flir cams etc on every phone.
The only DS emulator really worth using in my opinion is Drastic I tried a few other things like lemuroid and MelonDS before finally paying for Drastic.
