lol fixed it. So apparently I didn't have to edit the retroarch.cfg file I thought I had to, which was the one under config/retroarch/config. The one I had to edit was under "all", some sort of root directory not accesible through the File Manager. I had to use the Configuration Editor to make the change. Initially I had tried using the editor within File Manager (nano).
@actnash Also, just wanted to say that for the pi 1, quicknes and pocket SNES are the two emulators that are working great for me. Yoshi's Island runs almost full speed, with occasional stutters, but super mario world runs flawlessly. For NES, OpenGL driver, max swapchain= 1, video hard sync on =0, and frame delay=8. I got a NES classic for Christmas, but with these settings on the pi, it's very hard to tell the difference between the two. Graphics, input latency, and everything else is very comparable which is AWESOME. For SNES, Max swapchain=2 and frame delay=4. Turbo overclock makes all the difference for SNES.
