GBA Shaders and Resolution
#1
Photo 
As it is not possible to run GBA pixel perfect on a 320x240 display, I've tried different settings to get the best possible result.

Original res is 240x160, so I've set:
custom_viewport_height = "800"
custom_viewport_width = "1200"
That is 5x the original resolution

but the Image is not very sharp using the default settings, also the colors are too bright.

Unsing two shaders made it a lot better:
shader0 = "/opt/retropie/configs/all/retroarch/shaders/shaders/sharp-bilinear.glsl"
shader1 = "/home/pi/.config/retroarch/shaders/shaders/gamma2.glsl"


I'm using the mGBA Core.

Is there a better solution?
