    Finally an impressive showcase of 6502 load/store performance

    • @florianb3935
      @florianb3935 Місяць тому

      For the newbies here, what do you mean? I don't know about this computer, but I wonder how a 6502 can do so much, is that all prerendered? For reference, I'd expect something more like the GX4000 with that power, where drawing a single column of tiles per frame for scrolling, is already really an amazing performance 😅

    • @MichaelPuterbaugh
      @MichaelPuterbaugh Місяць тому +1

      It's not necessarily PRE-rendered, but it's a common homebrew technique in 8-bit computing to offload intensive computation to a peripheral coprocessor, leaving the main 6502 with nothing to do but copy data from the coprocessor to the output ports.
      Some feel this is cheating, other consider it a valid approach; it was in fact used during the 8-bit era, with 1984's Atari 2600 version of Pitfall 2 containing a custom chip designed to feed graphics and audio data as fast as it could be read.

    Respect, very impressive! The only thing I'm missing are credits to the original authors of the music and the art work. Iirc they're credited in the credits of 2nd reality, so would've been easy to add.

      I think it is custom to refer to/credit the original authors as a group, not individual members, only if they personally know them or had contact with them. Maybe during the part-credits the original individuals could still be credited.

    Very nifty, I thought some of these effects looked quite familiar and then I realized it was a remake of an OG demo for X16 ;) Is the relatively low rez of the plasma effect due to something VERA specific, or just due to early days of X16 exploration that'll inevitably refine?

    • @mooinglemur
      @mooinglemur  Місяць тому +4

      We'll have to see. The plasma effect is heavy on the CPU but light on RAM usage (the loading pause is preloading for the subsequent effect). I'm sure it can be improved upon with more precalc, and I look forward to seeing this demo outdone by something even more spectacular!

    Well, I'm still not certain that a 320×240 Doom port, even at the level of the Super NES version is possible unless it's on a cartridge with add-in chips, but I believe the likes of near perfect arcade ports of the likes of Space Harrier, Road Blasters, Aqua Jack, and Afterburner should be quite possible (within palette limits, of course), provided they're on a machine with at least 1 MB of High RAM. I even suspect that 640x480 ports of Pac Mania, Shinobi, and The Ninja Warriors are possible...

      It would be impossible to accomplish on something that is slower than a 486 PC, so they had to resort with Parallax scrolling.

      @jeffreyhullekes6866 Місяць тому +6

      It was also the last part added and there was time pressure to get the demo ready for release. There are several parts we could improve (a bit) but there is a point (after a year of work) you have to wrap it up. We are happy with the result: you can clearly see what kinds of things you can do with the x16. We hope it inspires others to create demos for this (or other) retro machines.

    Are drawing to an off-screen buffer and then blitting it to the video ram? Or are you drawing directing to video ram? If so, I thought the X16 wasn't good at direct access to video ram? Did the hardware get changed?

    • @TheBeeshSpweesh
      @TheBeeshSpweesh Місяць тому +5

      The VERA recently got some "FX" extensions which allow certain types of drawing and bitmap manipulation to be done faster. Without them, this demo wouldn't have been as accurate to the PC original.

    • @darksword1
      @darksword1 Місяць тому +3

      @@TheBeeshSpweesh yes, but my question still stands. Is the demo drawing directly to video memory or to some off-screen buffer and then blitting it to video mem? The CX16 was known for being very slow for writes to the Video mem because there was no direct access. So how are they drawing these effects?

    • @jeffreyhullekes6866
      @jeffreyhullekes6866 Місяць тому +4

      ​​​@darksword1 there are roughly 15 demo parts and they use all different kinds of techniques to create the (visual) effect needed. Asking if the demo uses an off-screen buffer cannot be answered (easily), since all these parts work differently. But for most of them: no. The x16 can write to VRAM as fast as you can towards RAM (linearly). It was never really the lack of DMA that slowed things down, more a lack of knowing/imagining how to do it without it. The FX extension has several clever helpers inside of VERA to speed up things quite a bit, but its still behind a 8-bit VERA port. However those helpers were made in such a way that you could still benefit from them greatly despite the port-like access to the VERA chip. And they are specifically aimed to speed up what would otherwise be cpu or bandwidth intensive tasks.

    • @akumanatt
      @akumanatt Місяць тому +4

      X16 has no DMA or blitter at all. This is just pure unrolled loop of memory port banging to the FX helper.

      That's right, I mean it's not even technically satanic since it's not inverted.. I guess they preferred to remove it so that it was "family friendly"..??
      Maybe it could be because they inspired themselves from the C64 version which also has this symbol removed, but for technical reasons
