Ha, yeah after looking at your pics, you are right.. The colors don't really drive me that nuts at the moment though, however if anyone comes up with a fix via reprogramming, please let us know! I might have to pick one up too!
I just got my cable today and I was pretty impressed with the results! Thank you so much for this! Now I just have to wire up sound and mount the connector.
@robbievgb I have a similar setup. Sophia -> RGB scart -> gscart switch -> framemeister -> Samsung pn64d8000
Which profile did you have selected on the framemeister?
The colors don't look too bad to me, however I am not comparing them to any rf source. I just know it looks miles better than the last time I had played it via rf (years ago?). I had the FirebrandX SNES profile on the framemeister selected just because I was too lazy to mess with it for testing. See the attached pics I took on my iPhone. If you want I can grab some more accurate snapshots from my ElgatoHD60 tomorrow.
Maybe it is your cable?
I got mine installed in my 5200 last night, however making a cable is out of my expertise. Would someone who knows how to make them sell me a db-9 to scart cable with the audio wired in per Simius' spec? I reached out to retro_console_accessories but I have yet to hear back from them.
