Hey all! I think I've been living with this problem for years and it never really registered that maybe something was wrong...
So, the full image isn't drawn to my CRT. I'd say in 240p, the bottom 10 lines or so are missing, and this is really weird, but it also stops drawing halfway through the last scanline.
Additionally, I'm guessing this is related, there's maybe an extra one or two scanlines above the top of my screen that are mostly white but changing colors. No pic because I adjusted my CRT to push that off the top and promptly forgot it was happening. But now that I'm actually giving this some thought, it's probably wrapping around and trying to draw the bottom part of the image before the first real scanline.
Is there anything I can do to diagnose and correct this? I am using a consumer 15khz NTSC TV, with VGA → GreenAntz → Component in. My crt_range is basically generic15 with some minor tweaking, but I can try to see if resetting it back to generic15 does anything.
Bottom of my screen in "ninja spirit" - you can see all but the first 3.5 lines of the HUD is missing.
What it's supposed to look like
This is just an example - the bottom appears to be cut off at some point in all progressive 15khz modes (in other words 240p and the surrounding range 220-244p or whatever).
Any ideas? Thank you very much!
