COMPO: ECM Demoeffect Comp

ECM Mode Demoeffect Competition

*** ECM Mode Demoeffect Competition ***

Competition Rules:

* The Effect must be a one-screener
* For ECM Mode only one Charset with 64 Chars is allowed
* The 64 Char Font is not allowed to be altered at runtime
* Play with your imagination. Maybe use the Petscii font in ECM mode
* Variations of the effect are allowed but it must be the same effect(code)
* Alteration or switching of the font on a per-line basis is not allowed ((linecrunching / etc.) set $d011/d016/d018/vic-bank only in init))

I knew if I waited long enough, there would be a single-screen ECM compo I could release that damn plasma at. Only took 20 years ;)

I made this some years ago. It was released at some Extend meeting, not sure exactly which one. https://csdb.dk/release/?id=196617. NOTE: This does not qualify as a ECM Demoeffect Compo entry, as it changes the charset and is not a single screener, though the principle of the effect is the same. The idea was to get as many plasma-fx to 4k as possible. Never finished it.

To whine a bit - I find fixed 64 char set counterproductive ;)

@Street Tuff: btw, welcome to the noble club of people who made a fuckin' mistake of creating compo with limitations at csdb :D Good luck with usual guys here xD

I'm a bit confused. May $d011/16/18 and $dd00 be changed once per video frame or not (for double-buffering, smooth scrolling, etc.)?
And the $d02x colour registers may be changed more often than that? Or not, because "no rasters"? :)

It says "set $d011/d016/d018/vic-bank only in init". I interpret that as no double buffering and no smooth scrolling.

Quoting Street Tuff
...
animations are allowed. $d011, $d018 and vic-bank can be changed once per screen.

So I don't get most of the whining, apart frome FLD and $d016 tech tech everything seems to be allowed meanwhile :)
but $d018 only once per screen... *WHINE!*
