I've written some rotating "demos" in asm and high level languages on 286-486 computers, and have at least some knowledge of the VIC-computer internals. But I understood almost nothing of this during my first watch. Probably need to look up the word shear, or similar :)
I am so glad you took a turn on this part of the demo. I hope to see more demos being pick a part like this. Next Level 100 games part would be fun to see.
@@MartinPiper6502 The way you explain makes it easy to follow along and get into all the details. Been following you for a loooong time now and it's like C-64 meditation to watch/listen how you explain all. :)
Extremely impressive. Parallax by swapping tiles was a pretty common thing on many 8-bit systems but I haven't seen it with this much rotation before. If any... Of course Amiga Demos did similar things but they had the blitter, dual playfield and sprites so many other techniques. I don't even know if hotswapping a screen full of text would work on the Ami
I know right? :) This is effect is quite new, it's done differently to other similar visual effects, I have no doubt there are other new C64 VIC effects waiting to be found.
can't wait to see what kind of c64 demos and games gpt8 comes up with, where it optimizes every byte of memory and cycle mixing every mode in combinations in space and time, in ways no human would conceive of, to facilitate surprising game types and depth never imagined on the old hardware, generated anew on demand and personalised, 24/7...
Still pretty darn clever. Shows the flexibility of the VIC-II chip for sure. Still finding new ways to do things with the VIC-II and the SID chip as well, even 40+ years later.
@@MartinPiper6502 Yep. I can remember vividly the first time I saw a demo with the top and bottom borders opened up. I wonder who was the first demo coder to figure that one out?
@@MartinPiper6502 Funny it took the coders 6 more months to figure out side borders. Sadly I have no idea what some of the effects listed are, such as FLD and VSP. I guess this is a page for demo-sceners so that makes sense.
This is awesome! Would love to see more analyses of demos.
More to come!

Looks like the horizontal $d016 scroll register is being used in a raster to compensate the 8 pixel wide character jumps.
Yes as pointed out at 1:30

I plan to do more demos. The tricky thing is to make them understandable.

Well the original Amiga was certainly capable of redrawing the screen, but it didn't have a "text mode" as such, it was all bit planes based.
What a demo! Someone had a LOT of thoughts on this one. Subbed!
Yeah it's a really cool effect.
Thanks! 🙂
Thank you for the kind support :)
I think Steve Mould showed in a video how every rotation is just a couple of integer translations and sheering operations
Really nice deep dive ! More demo effects deep dive would of course be welcome :)
Glad you like it. More to come!
@@MartinPiper6502 Excellent news! Thanks, I love these kind of deep dives.
So good watching this - thanks, Dude!
Glad you enjoyed it!
what is this sorcery?!
I just watched your WinCE video before this one 😂❤
It is the magic of Serato. He is a crazy man.

@@MartinPiper6502it's a similar effect to m.ruclips.net/video/Q5iqSzKYZoQ/видео.html
yes very much like that
Great video! Thank you.
Awesome awesome awesome awesome awesome 😎 ...this video is my happy place.
Thank you so much 😀

Its says in debug....standard text mode........but it looks quite crisp is .its 2 colors and if its interupting the resolution is 320x400
@Mr.1.i yes it's in hires text mode
@MartinPiper6502 there are pokes that allow you to use the boarder for graphical instruction
@@Mr.1.i yes I'll be getting into those in another video

I'm very sure new effects are yet to be found.

This page seems to have a list of first use of effects codebase64.org/doku.php?id=base:demo_world_records_and_world_firsts#border_top_bottom

lovely
great stuff
Does this demo work on a VICE emulator, I know it is very good but this demo will test it for sure.
Yes, even old Vice in ICU64 runs the demo.
You could just say that they are quickly changing premade characters.
