A few weeks back I added S-Video to my PAL 2600Jr. Razor sharp video, except some of the colour is a bit off. This is the circuit I ended up using:
I didn't solder directly to the TIA pins (except for luma 1, which I traced to the bottom-right leg of the CD4045, so I soldered to that chip) as usually recommended, though I think the luma signal is the problem. Here's some screen captures:
Pacman'a colours are pretty good. Note these captures were taken from a DVD recorder. I had to connect the Atari with an S-Video to composite adapter. Then I took the captures from the PC. The video quality from these pics is nothing compared to the TV in terms of clarity, but they show the problem.
Plus an emulator capture.
Berzerk (second wave, they should be orange.)
Chopper Command. The helicopter is too dark.
Kung Fu Master. The guys are too dark.
Winter Games. The snow is heaps off.
Anyone have any ideas what's going on? Thanks.
