Demos using the extras that came in ECS?
Superhires, 1MB addressable chipmem. Are there any more features (or bugs or differences) that ECS added? And do you guys know any demos that actually used them?

There was also a flag that would give you a guaranteed black border regardless of the palette entry in color register 0. I think you could also set the sprites to overlap the border instead of being blocked out by it.
As for demos that used these effects, I'm not really a member of the scene so I can't think of any. |

Satisfaction Guaranteed - by pearl , uses the ehb mode of ecs chipset to fade colours. When run on ocs, the colours stay solid.

Do you mean ECS Agnus only ("ECS Amiga 500" generally means ECS Agnus with original Denise) or both ECS Agnus and Denise?
Borderblank is probably most useful ECS Denise feature. ECS superhires is useless (max 4 colors from palette of 64(!) colors..), the rest are improved genlock features. (btw, EHB is OCS feature) EDIT: bordersprite is AGA-only. |

Long blits, useful for c2p on 68000 (needs less blitter passes), I don't know if any demo using such c2p has been released (yet) though.

The only program I know of that used the ECS Super-High-Res mode was a titler that did foreground, background and 2 shades of antialiasing for broadcast quality genlocked text. The blackborder effect was only needed in EHB mode and so on and was made obsolete in AGA by bigger addressable palettes.

And >512K chip? Lots of prods?
(Superhires and > 512k chip... is there something else in ECS? Border sprites, and what else? Not sure the the Wikipedia article has all of it, not sure if there is more.) Oh well, titlers aren't demos. Next! ![]() |

I did a demo which uses ECS features!
It is called "BeamControl". You can find it on aminet, demo/euro/BeamCtrl.lha It detects the chipset and adapts to the gfx features available. I have to say that some people don't consider it a demo because it's clearly and explicitely technical-oriented instead of being artistically-oriented. But of course I disagree ![]() ![]() ![]() IMHO, in their true essence, demos cannot ignore techinical features, otherwise they get into the realm of conventional computer graphics. In the early days, demos were just demonstration of techinical abilities (e.g. "look how fast my sinusscroller runs!"). Beamcontrol is such a kind of demo, it shows the capability of switching while running resolution and (most important) video frequencies. Critiques and comments are welcome!! ![]() |
