Okay spent some more time doing a few tests of the SNS-CPU-RGB-02. My notes are:

- Uses S-RGB A BA6596F encoder, same as SNS-101 or model 2 SNES systems. Seems to be the best video encoder for SNES systems according to izarate's findings.
- Does S-Video output native unlike SNS-101/model 2 SNES systems. I'm not sure why the SNES 2 systems don't do S-video off hand but it's a major down side of those systems no doubt.
- My NTSC SNES RGB cable works great with this system where my SNS-CPU-GPM-01 system would display a very bright/washed out picture. There has been a lot of confusion with NTSC SNES RGB cables where an extra cap needs to be installed, this might all boil down to a board revision problem which I've never seen it mentioned.

Hopefully more people can contribute so we can figure out what is truly the "best" SNES board revision and exactly how many exist. A lot of work like this has been done for the Genesis side but not the SNES.
