Heaven/TQA Posted April 16, 2017 Share Posted April 16, 2017 today we have released a new demo for Atari Lynx here at Revision 2017 - worlds largest demo scene event: You can grab the rom: http://www.evilshirt.com/_ataristuff/dsr_elements_revision2017.zip this rom is optimised for Mednafen but not Handy emulator nor real hw (thou it runs of course on real HW but timings are wrong). I will release as soon as I can the "real HW" edition. (sad that mednafen differs to Handy differes to real hw). 16 Quote Link to comment Share on other sites More sharing options...

sirlynxalot Posted April 16, 2017 Share Posted April 16, 2017 Watched the video, looks pretty cool! The music itself is pretty impressive to say nothing of the graphical effects on display. 1 Quote Link to comment Share on other sites More sharing options...

Heaven/TQA Posted April 17, 2017 Author Share Posted April 17, 2017 danke. "Do we have a Lynx here?" ;=) but I guess people have not appreciated it... that it is a 8bit console... Quote Link to comment Share on other sites More sharing options...
LordKraken Posted April 17, 2017 Share Posted April 17, 2017 May I ask you what kind of technic you use to do bitmap rotation? (just the overall idea, not the details ) Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted April 17, 2017 Author Share Posted April 17, 2017 (edited) May I ask you what kind of technic you use to do bitmap rotation? (just the overall idea, not the details ) are familiar with so called "warp" or "twirl" or "tunnel" effects? if so... all 3 fx are the same principle... beware "spoiler" alarm... http://jsfiddle.net/popmilo/1L23xh20/ actually thanks to Lynx hardware you simply calculate 1 sprite while the other 3 are flipped copies of that... so standard demo coding techniques used... unroll code for complete texture processing... rendering not on screen but directly into an unpacked sprite structure so the blitter can do his job... or Suzy Edited April 17, 2017 by Heaven/TQA Quote Link to comment Share on other sites More sharing options...
sage Posted April 17, 2017 Share Posted April 17, 2017 ... same technique as in 'lynx reloaded' tunnel effect and picture swirl. :-) Q: I noticed that there are quirks on real hardware. Something fishy with double buffering? Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted April 17, 2017 Author Share Posted April 17, 2017 sage... yeah... I know... need to fix timings of the "witch" parts... here Handy seems more accurate while in other parts Mednafen seems better even both work on similar core. what about VBL IRQ using blitter? possible?

sage Posted April 18, 2017 Share Posted April 18, 2017 (edited) you shouldnt use suzy in interrupts, because you can not be sure that you intercept some other action. Read the docs for more details. (actually, I do not see any reason to do that ... switching buffers in VBL and checking the corresponding VSYNC bits or a flag should be a more appropiate way to do it) Edited April 18, 2017 by sage Quote Link to comment Share on other sites More sharing options...
Fadest Posted April 18, 2017 Share Posted April 18, 2017 Wow, really impressive. I love the effect just after the greetings, I have not watched demo for a while, so this is one I am not used to see. But the other one are very good also. Congrats guys ! Quote Link to comment Share on other sites More sharing options...

(actually, I do not see any reason to do that ... switching buffers in VBL and checking the corresponding VSYNC bits or a flag should be a more appropiate way to do it) yeah. I was using "check for raster position" waitloop but somehow it's slower on real hw than in mednafen... I guess it's because of the suzy timings. I assume the blitting operation of the witch take longer in handy and real hw so I miss the right spot to catch the VBL. Quote Link to comment Share on other sites More sharing options...
