  1. The display list is hard coded and it's pretty big at around 750 bytes. Rest of the viewer is only about 100 bytes or so. Making RastaSlide I found compressing the kernel and picture tended to gave a smaller file size than changing to fewer instructions in the kernel and also compressing!
  2. RastaSlide - RastaConverter Slide Show Maker - version 2.7 Changes in version 2.7 - Includes Drpeter's version 4 "Tutorial Walkthrough" for artefact correction - Added detection of an extra cause of HPOS line artefacts described in that guide - Folders of slides can be added now as well as folders of RastaConverter pictures - PMG file output in same MADS hex data format as RastaConverter RastaSlide 2.7.zip sheddy_peacock_feather.xex
  3. The fixing guide is all down to @drpeter. Very comprehensive tutorial and technical background on RastaConverter. I think this is the latest version: I added some timing info comments and "line artefact detection" to RastaSlide disassembler to help with manually fixing artefacts although we still end up with false positives. So there is a base to build on an automatic fix attempt. I haven't come up with an approach that is simple enough for me to implement confidently yet though.
  4. RastaSlide - RastaConverter Slide Show Maker - version 2.6 Changes in version 2.6 - Fixed bug on optimized kernel trailing loads getting undone, and to the wrong line - Optimizer removes player colour writes(leaving last) when there is no player data The bug caused minor visual differences at the bottom of a very few RastaConverter pictures as slides so recommend to update RastaSlide 2.6.zip sheddy_heart_in_sand.xex
  5. RastaSlide - RastaConverter Slide Show Maker - version 2.5 Changes in version 2.5 - Optimizer now removes HPOS writes when there is no player data for their range, for small compression gain and reducing false positives of possible artefacts using "#disassemble optimized" - Fixed bugs with false positive detection of possible artefacts excluding real ones - Timing and artefact comments only produced with disassembly tools and not slide add - Fixed problems displaying 3 pictures made with a very early(beta?) RastaConverter: "cliff", "purple_nurple" and "sakuras2b" sheddy_umbrella.xex RastaSlide 2.5.zip
  6. RastaSlide - RastaConverter Slide Show Maker - version 2.4 Changes in version 2.4 - Removed false positives of possible artefacts on duplicate writes by "#disassemble" - Includes Drpeter's latest version 3 "Tutorial Walkthrough" for artefact correction Thanks to Drpeter for our messaging about the false positives which I hadn't given enough thought about in the above case. RastaSlide 2.4.zip
  7. RastaSlide - RastaConverter Slide Show Maker - version 2.3 Changes in version 2.3 - Remove intermediate "#disassemble optimized" files which otherwise get used to build - Added detection for newly discovered 6 colour clock HPOS thermal delay artefacts - Reduced false positives of possible artefacts (thanks to Drpeter) Very interesting this odd problem hasn't been noticed before. Could it be related to age of boards/chips too - Would a brand new Atari in 1979 have had the same issue? RastaSlide 2.3.zip

  9. Ah yes. Thanks! I hadn't noticed it had translated. That 6502 is much more readable in the original Polish now.
  10. Just having a look at the source. "Jan”, "you", "constant". Macros? What do they do please?
  11. Run address is right at the end. E0 02 E1 02 00 58 Change to E2 02 E3 02 00 58 (Load $5800 into INI address $2E2, $2E3) Well, that doesn't seem to work. I thought it might be because Rastaconverter trashes DOSVEC, but changing it to use a different zero page still crashes after the picture is done. Must be missing something dumb as Actually it does work. It was just too quick to notice! Problem was I chose another Rastaconverter picture to be the XEX test to load after the 1st picture. Because the 2nd picture loads instantly in the emulator, still having the space bar pressed from exiting the 1st picture causes the 2nd to exit immediately... Anything except another Rastaconverter picture XEX to load after will probably be just fine.
  12. Run address is right at the end. E0 02 E1 02 00 58 Change to E2 02 E3 02 00 58 (Load $5800 into INI address $2E2, $2E3) Well, that doesn't seem to work. I thought it might be because Rastaconverter trashes DOSVEC, but changing it to use a different zero page still crashes after the picture is done. Must be missing something dumb as RastaSlides are chained together in the XEX in the same way
  13. Good question. Probably, change the Rastaconverter run address to be an ini address instead. Then assuming no source, remove the 1st 2 "ff" header bytes of the XEX file that is to be loaded afterwards and append it to the Rastaconverter XEX. Maybe you don't need to remove the header bytes though. Finding the run address of the Rastaconverter picture without source might be a pain. Can send you a bit more specific if you need. Kind regards Chris

  16. slightly better deflate result: zopfli --i4000 --deflate conan.gfx 1,598 conan.gfx.deflate

  18. Rybags is right there are some amazing wallpapers. Sometimes, somehow, they still can maintain some of their glory with Atari limitations. Not sure if the rockpools was for Mac or not but the original photo (hopefully not photoshopped colours) is stunning sheddy_rockpools.xex sheddy_handsfull.xex
  19. Just some nice simple pics sheddy_dino_pencilprod.xex sheddy_paper_beach.xex
  20. RastaSlide - RastaConverter Slide Show Maker - Version 2.2 Changes since version 2.1 - Fixed "#build centred output" issue where pictures built don't display in RastaSlide - Disassembler changed to deal with existing "#build centred output" pictures Yeah, I didn't check my own centered pictures worked in RastaSlide. Duh. They work fine as stand-alone pictures and add OK with no error, but don't display properly in the slide show. I'd advise anyone using RastaSlide to make centered pictures to update to this version RastaSlide 2.2.zip
