So I bought a cheap RGB cable for the SNES. It looked awful and was missing detail in bright scenes as in clipping because it's too bright.
I modified it following this http://members.optusnet.com.au/eviltim/ ... nespal.png
I followed that exactly but I used 100ohms instead of 75ohm and 220ohm instead of 180ohm because that's all I have. I also used pin 7 luma for sync instead of pin 9.
But now I get some buzzing in the audio on bright scenes and it doesn't seem to auto switch to AV Automatically like it should. It's exactly like the picture except pin7 and the different resistors. All ground chained together going to pin6.
What might be wrong, any ideas?
Figured out my cable didn't have 12v and I was just connecting a second GND cable to where 12v was supposed to be. I chained the other ground cable to 5 and 6 instead and used the second ground cable as 12v to get the 4:3 aspect ratio. I still have the buzzing audio but at least that's one thing out of the way for now. Is anything wrong with the diagram I have linked or could the different resistors be affecting it?
