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))

Beat me to it. I was going to launch the CSDb Compo Compo but realized that I'm too lazy. The most outlandish, while still feasible, rules win.

And the rules for that compo must of course also be super confusing and change continuously. :D

Bring it on! Then I can release my useless "three vertical border scrollers" routine :-)

I was referring to the difference between ECM and other modes =)

"as long as $d016, $d018, $d011 and Vic-Bank stays untouched per frame"

How about $D056, $D0D8, $D2D1? :-)

Also.. when you says "untouched per frame".. is that "they can be changed each frame - but not within the frame".. or that they can only be set once at the start of the demo..?

Re: Square Booze .. "Reading the rules more carefully now this entry should probably be disqualified since I do change $d016 per frame. Street Tuff didn't explicitly allow touching scroll registers and he explicitly disallowed touching $d016 except on init. Groepaz raised the question but was unanswered."

IMO, D016 and D011 changes should surely be allowed - so long as they're only used for smooth scrolling and done once per frame?

With a month to go, I'd imagine most would be ok with this rule being clarified...

I would just leave it in the compo and let Street Tuff sort it all out.

"set $d011/d016/d018/vic-bank only in init" - pretty clear to me.
