400 x 240 fullscreen

[Gmax011]

Is there any way to play gba games with the firmware on top screen of the 3ds and on 400 x 240? I don't like the black borders (I know that's the native resolution of gba games, but I prefer playing on fullscren).

This is currently not supported and honestly i don't know if i will add it any time soon. Fullscreen scaling will destroy the aspect ratio and doesn't bring any benefit in terms of scaling artifacts.
