Steve Guidi Posted November 25, 2020 Share Posted November 25, 2020 Hi everyone! I've been puzzled by the lack of clarity in the image that my composite-modded 2600 Jr produces. I have a feeling that what I see is normal, but I can't rule out choosing a poor mod. I've tried connecting my 2600 Jr. to my computer via an upscaler and a capture card, as well as directly to a LCD TV that supports composite video; both results are similar. To illustrate, below is a screenshot of "Basic Programming" produced by my NTSC 2600 Jr, and interpreted by my upscaler and video capture card. And the following is a similar screenshot which appears to be captured from an emulator. My image is a bit dark, and that can tweaked on the composite mod circuit by replacing a resistor. However, I can't seem to produce solid text characters -- perhaps my TV and upscaler are interpreting an interlaced signal and the 16:9 upscaling is displaying the artifacts of that. Is the text display in my image normal -- perhaps the emulator is intentionally producing a clearer image? Quote Link to comment Share on other sites More sharing options...
+-^CrossBow^- Posted November 27, 2020 Share Posted November 27, 2020 Pretty sure the text in basic programming is using flickering to simulate a more solid character and with a CRT the phosphor persistence would make it less noticeable. Many emulators too can make it appear to be more smooth than it is. So I think it is just the way your TV is interpreting the signal and flickering. What do the asteroid rocks look like as a comparison? 1 Quote Link to comment Share on other sites More sharing options...

The asteroid rocks are clearly flickering through my upscaler and video capture card. On my TV, the signal is not interpreted as cleanly -- sometimes the asteroids have jagged or incomplete edges, probably caused by some of the scan lines in the flickered signal being dropped.
