I suspect that I have it soldered to the incorrect pin because when I disconnect it completely I see no difference in picture and I am still seeing the dot crawl. It seems that this is not getting sent to the blanking pin to on the jungle chip. I also tried applying 3.3 and 5V to the line and didn't see any difference other than some faint rolling lines going up the screen so I disconnected it immediately.MarkOZLAD wrote:That sounds like you are only seeing composite video.

At first I wasn't sure if I was seeing component or RGB because I am still seeing dot crawl on my everdrive's menu screen for the N64 but I did notice that the colors in the OSD are different in some places where they intersect with the game image when only when using my SCART connection (RGB).
I think the everdrive menu uses one of the N64's high resolution modes so I'm not sure if dot crawl on text is normal or not with RGB. I am using the Composite video for sync. Would using a sync stripper help with dot crawl?
Ok so I FINALLY got it working! Putting 5v with 75 ohms to ground and a 3.3k in-line would not work but bypassing all the resistors and putting 5v direct worked!
Composite and rgb are like night and day my only issue is that the rgb picture is pretty dim any ideas to fix the dimness? Could too much voltage to blanking cause dimming?
