Event id #3003 : Only Sprites Compo

Competition Rules:

* You can ONLY display sprites - no chars or bitmaps. Magic byte(s) CAN be used.
* Change any VIC properties that you like
* The Effect must be a one-screener in one PRG (preferably compressed) (no disk streaming)
* Variations of the effect are allowed
* Interaction is allowed - make it a game if you like ;-p
* Music is allowed and encouraged
* Borders can of course be removed

Winner will be chosen based on CSDB's rankings.

Perhaps this old junk will do:

Starball Effect
Starfield

Though, it makes no sense to entry entries that have already been voted on. So, perhaps not.

Mixer, that's not junk at all. Those are gems!

My plan was for a “no badlines” compo, but I guess this is effectively the same thing šŸ˜€

Well...

Not quite. Using "linecrunching", you can display char/bitmap data without any badline during the entire frame, repeating the linebuffer content while omitting any DMA to update it. =)

Hehe, so much time before the compo has even started to whine about rules, you are doomed ;)

Don't you need one badline at the top to kick it off? Or does the internal vic buffer retain what was there previously? But yeah creative cheating like that is what you'd hope for in a compo.

you can infinitely supress badlines, and the last one red is displayed from the internal VICII buffer forever. VICII stores internally 40x4bit d800 color info and 40x8 bits of char data.

The buffer content is kept across video frames, so can do complete video frames with char/bitmap content entirely without badlines.

It's not creative cheating for a "no badlines" compo, imho, but it would be outlawed in a "sprites and idle byte only" compo. =)

Neat, then yes, we get the first arcane rule "clarification" for my fictional nonexistent no badlines compo, that you're allowed to set the internal 40x12 buffer once on startup :)
