I noticed that most of the SNES cores don’t really smooth the graphics very well. For instance playing the SNES9X emulator without Retroarch but standalone by itself, I have options like: output image processing/6XBRZ that really filter and smooth out the pixels in any one SNES game.
But the SNES cores in Retroarch are missing these options. So, are there any other SNES Cores that can do this? Really filter and smooth out the graphics? Or did I miss these options somehow in SNES9X or the other SNES cores?
