Is this emulator/How is your quality so good?
No I am (probably) not playing on emulator. All my old console are outputting RGB and then being upscaled/line quadrupled through my OSSC. This makes for really nice video quality.

RGB is simply an analog video signal like composite or s-video except much higher quality. The image above is a good example. RGB separates each of the colors (Red, Green and Blue) into their own signal, which are then blended together on your display.

Open Source Scan Converter (OSSC) is a low-latency video digitizer and scan converter board designed mainly for connecting retro video game consoles and home computers into modern displays. It converts analog RGB/component video into digital format, and doubles, triples, quadruples or even quintuples scanlines of a single frame if necessary to generate a valid mode for digital TVs or monitors. Most retro consoles output 240p. So for example when line tripled you end up with a 720p video signal. 240 x 3 = 720.

edit: I'm no longer using a pexhdcap as my capture card. I'm now using a datapath VisionRGB-E1S and will be trying to stream in 1080p for retro stuff.
