  1. looks great would be possible to share your dev environment?
  2. ST) - more colors: use BLiTTER to show more colors than Spectrum512 - new tools for more colors: https://atariage.com/forums/topic/292817-spectrum-512-4096-or-other-editors/?tab=comments#comment-4306630 - new video modes: 1280x200 mono, 320x400 with 4 colors, 160x400 with 16 colors: http://www.atari-forum.com/viewtopic.php?t=34108 - new overscan: invented by Evil/DHS, it uses less cycles than standard one, STE only; TT) Standard resolutions: 1280/960 mono; 640x480 with 16 colors and 320x480 with 256 colors There were no any additional investigations/attempts to boost resolution besides demo http://www.pouet.net/prod.php?which=52339 which shows more than 16 colors in 640x480 Falcon) It has fully programmable video chip, which is only limited by its internal pixel clock: 32MHz and 25MHz. A color depth depends on the main bus speed. In case of standard Falcon it is max 1/2 pixel clock for 16bit color. 256 color mode works on full pixel clock. You can boost its graphical capabilities: - add the bus speeder (e.g. Phantom) - not so easy - add faster external pixel clock - easy
  3. yep, Leonard did a great job, but this is a software record for 16x16 two bitplane (4 colors) sprites. In case of hardware blitter's sprites, Lynx is still ahead of both machines: - STE: 21 sprites 32x32 16 colors with background clearing: - STE: 17 sprites 32x32 16 colors with restoring background: - A500: 13 sprites 32x32 16 colors with restoring background - A500 with FastRam: 21 sprites 32x32 16 colors with restoring background
  4. I'm far from judging Lynx, I just see a different between two 34 year old solutions - amiga's one and Atari's one. For a "clean" mode the first one reaches 1.79MB/s and the second one 4MB/s - thanks to using all available memory slots. We don't know yet how internally Lynx's blitter works, but we know it can shows much much more sprites in one VBL than amiga and ST gathered together.
  5. yep, but I would not use a word 'best' in that case
  6. There is another explanation: 'dma' channels can have different memory slots access, e.g source uses 'even' and destination ' odd' - as it is done in amiga blitter. Therefore, when you use only destination channel, 'even' cycles are free, and there no is time difference between 'copy' and 'clear.'
  7. besides DML tool we have other also great tools: Zerkman's MPP: https://github.com/zerkman/mpp http://zerkman.sector1.fr/index.php?post/2012/10/08/Atari-ST-Multipalette-Picture-file-format Antiques demo: https://www.pouet.net/prod.php?which=59066 Retro Image Tool by Anima: http://tool.anides.de/ Also I wonder which tool was used by Cyg/Blabla in their demos: https://www.pouet.net/prod.php?which=62142
  8. that's a lot of data - 117 504 pixels, 58k bytes in case of 16 color image
  9. can you pls post that link? interesting finding
  10. 1) I have no idea, I didn't check CPU copy code. is it LDA $XX,Y / STA $XX,Y? 2) Your file was fine for me, Saint's Lynx SD card easily accepts that format. what about horizontal line? It is visible under Handy, but not on the real hardware.
  11. @Fadest thx for that hint, fortunately there were no need to modify the file, it works fine with Saint's Lynx SD card Interesting is that my figures are a bit different than Fadest's one: 229 vs 228 And also on my Lynx II there is no a white horizontal line
  12. ok, I'ill do that today evening
