3DS-like graphics

is it possible to make the games look more like the actual 3DS (pixel-ish)
itl also improve speed for crappy pc’s

I suppose, something like reshade + crt shader, i haven’t checked if someone made preset for citra though, you may have to make it yourself.

I think what you’re asking for is native resolution to match the 3DS screen resolution (400 x 240). Go to Emulation -> Configure -> Graphics and change Internal Resolution to Native Resolution.
