    Im try to use as many Retroarch based emulators in RetroPie but so far each emulator doesn’t seem to have bilinear filtering applied to the graphics and thus the graphics are very pixelated (i think point filtering is being used?). How do i enable the filter for retroarch based emulators please?

    Open /opt/retropie/configs/all/retroarch.cfg and set “video_smooth = true”.

    Hmmm this is what i though that need to be done, so i changed “video_smooth” to true but it didnt appear to change anything. May another option was enabled that cause this video smooth option not to work? If i delete the retroarch.cfg file the next time i load a retroarch based emulator with it automatically create another default retroarch.cfg file?

    Look under /opt/retropie/configs/!system!/retroarch.cfg. Some of these configs disable bilineae filtering.

    Thanks worked a treat, im now trying to get all retroarch emulators working, as these appear to be the best and will share a universal config over all the systems

    I tried setting video_smooth to true for my nes core (nestopia) and thought it looked very fuzzy. I’ve seen pixel interpolation used on nes emulators on the PC that looked great so this was a pretty big disappointment. Any other suggestions for reducing pixelation without losing much perceived sharpness.

    Maybe use one of the retroarch shaders will do the job for you?
