  1. Good to know. Thanks for going to trouble of running on physical hardware and connecting to PC for video capture.
  2. Neither Sony Bravia TV seems to have a non-scaled option. I don't know that there is any way to turn image processing off either (there is a Standard setting, but the TVs still probably apply at minimum a spatial filter when performing the upscaling). I looked a bit into other connections, and looked like i'd have to go for a $25 s-video cable connected to some sort of upscaler which outputs hdmi ($140), and decided not worth it at the moment. If someone knows a cheaper route, please let me know. I may purchase an s-video cable, and try connecting to family members tv which has s-video connection. Otherwise, i plan to move any future programming to newest-patreon build of BigPEmu for debugger, use Virtual Jaguar to ensure to ensure functionality and display, and then use my current Sony Bravias (in all rainbow glory), as a run time check on physical hardware to ensure functionality, but not display.
  3. Searching for keyword 'rainbow' in general forum (instead of programming forum) came up with a few hits suggesting issue occurs with composite cables. Maybe issue is more pronounced with static, high-constast line/background.
  4. If the RMW flag of bitmap object (for object processor) was set by accident, i would expect Row4 to exhibit rainbow effect as well. I even explicitly cleared the RMW flag bit at one point, and still had the issue.
  5. Horizontal and vertical lines seem fine. Any angle deviating from horizontal or vertical exhibits the problem. (Though i do see where tv filters may be impacting first and last pixel of horizontal/vertical lines a bit)
  6. Has anyone had problem with display of solid color lines over a solid color background, on flatpanel tvs? But displays fine in emulators. See attached images, source, and assembler. Attached images are what i get. Beginning to think i should get ahold of a CRT TV and see if the problem is present or not. ;;; Draw some test lines to display a problem. Horizontal and vertical lines seem to display as expected color. ;;; However all other lines seem to display as if they had increasing pixels values, and pixel values were indexes into rainbow colormap. ;;; The below code can be viewed as displaying 4 rows of lines. ;;; Top row has 4 groups of lines, leftmost to rightmost ;;; Three contiguous 45 degree lines ;;; Two contiguous 45 degree lines ;;; Two 45 degree lines seperated by one blank 45 degree line ;;; Two 45 degree lines seperated by two contiguous blank 45 degree lines ;;; Second from top row has one group of lines ;;; Several contiguous 45 degree lines ;;; Third row has 3 groups of lines, leftmost to rightmost ;;; Single vertical line ;;; Single 45 degree line ;;; Single horizontal line ;;; Fourth row has 1 group of lines ;;; Several contiguous horizontal lines ;;; ;;; Started with a program calling blitter to draw lines for polygons, etc, and displayed fine on virtual jaguar. ;;; Moved to skunkboard, and got rainbow effect. Tried in BigPEmu, and BigPEmu displays fine (no rainbow effect), so i don't think BigPEmu new debug capabilities will help track this down. ;;; Back to skunkboard, problem persists. Composite outputs from jaguar to Sony Bravia flatpanel 2010 model and Sony Bravia flatpanel 2018 model both exhibit the rainbow effect. ;;; Switched from painting lines in framebuffer from blitter, to 68k to reduce number of variables. ;;; Same issue. ;;; Does appear spatial, and likely spatial temporal filters, are being applied by the Sony Bravia flatpanels, as cycling through different display settings (eg. cinema, game, vivid) change the display to be more or less pronounced ;;; With at least some of the display settings, and gray background with intended black lines, i could see some of the rainbow colors change during first few seconds of display (on newer tv, not older tv), making me think there is a temporal aspect of filters new Sony Bravia tvs are applying. ;;; ;;; Is the issue: ;;; a) Incorrect initializition of physical Jaguar hardware, but Virtual Jaguar and BigPEmu are initializing correctly? ;;; b) A flatpanel tv display issue? ;;; c) Combination of composite video feed and flatpanel tv display issue?

  7. There seems to be a repeating pattern of profanity in the videos. This video also includes lyrics i am not allowed to repeat due to my skin color.
  8. The AI has continued writing text and even some code in the intermediate 6 months between posts: https://github.com/A-C-Rosenfeldt/AtariJag6DoFtexture60fps/commits/main I don't think the new code from last couple weeks will compile on anything, unless C# syntax allows for a do while loop, without the while keyword present.
  9. Poster is back. Very ratio'd:
  10. There is another page or so below what i've attached, that is pertinent as well. Attached tells you what address PC will jump to on interrupt. If this doesn't answer your question, you probably need to ask a more specific question.
