@dankcushions thank you very much for the info. I had another question though . It says to ectract a file into a directory but i dont know how to do that

@epd probably. I am on a 15" screen and it is a noticeable change. Try fear effect. When in a game the character is really noticeable because the background is crap so the charater looks good compared to it when you turn on the enhaced mode.

@edmaul69 great, please do and let me know how it goes!

This should remove all dithering effects that the emulator explicitly added - but obviously keeping any that the games had originally.

another thing you can do is change the retroarch video driver to dispmanx which is said to save 1 frame off the input latency. i haven't personally done this as it has some side-effects (no shaders, no OSD, no screen rotate)

You're playing an old console which had a low res output on a TV which has a high resolution (HD), thats why it looks so bad. Beside back in the days we thought that the graphics looked good because we didn't knew any better.

I'm using the smooth video option and the games look very good, the PSX emu had an extra graphic enhancer option when I used that option the PSX games did lag. Maybe it works better on a overclocked Pi.

Some games look very good pixelated, for an example Donkey Kong Country 2 on the SNES looks very good without the smooth option.

I have always set up via Retroarch options and it's listed as something like enhance resolution (can't remember the exact name), but that is on the Raspberry Pi builds. I always find it because it's the option right above the speed hack.

On the PC, there may be other options for enhancement.

I've enabled shaders and video smoothing through the Configuration Editor
