CSY 2100 clone color adjustment (SCART to YUV converter)
I hoped to find a video like this when I got my converter, but since I didn't, I made one for the next person who does. ;) FYI, I get my RGB/SCART cables from http://www.retrogamingcables.com , except for my "universal" cable for my NTSC SNES & Saturn (which came from an HK ebay seller, and really is just DC, SNES, Saturn, PS2, PAL Gamecube, & Xbox). I got my box from Specialty AV for about $50.
The controls are (by knob number):
1: Yellow/blue balance
3: Red/green balance
4:Red/yellow balance (very subtle)
6: Color intensity
NOTE: The above labels are just how I perceive what those knobs do. If your have proper technical terms or more info, I would be more than happy to correct them and credit you.
