Pretty naming. I wonder how many entries there were at Sillyventure VCS compo. Also people seem to have "similar ideas" when it comes to "What the f... could be done at all on this inferior .... platform" so we established a real competition. Cool.

My favorite from the vcs entries of the party - if only for the rotating checkerboards'n'stuff :)

Great effects, although the music was really lacking.

Nice stuff, I like the rotozoomer, will have to take a peek in the source and see how that works! :)

Nice one, the rotator kicks ass! :)

JAC: there were four VCS entries.
Yours, this, noice and one that mixed sound in realtime, can't remember specifics of that last one since I was drunk and very tired :<

Oh and thumb up !
Don't stop doing VCS stuff tjoppen :)

Ferris: Yeah, I'd have to agree. I'm not really much of a musician, but luckily I had the sense to keep it short.

Sdw: The rotozoomers were probably the easiest to pull off. The goal was to one-up ilmarque's framebuffer rotozoomer since it only updates a quarter of the screen per frame - these ones redraw everything (since they don't use a buffer), but with lower horizontal resolution. So it's a bit of a toss-up.
The plasma is also a one-up, being quite a bit higher res than the one in Doctor :)

oasiz: I still have several pages of ideas to try out, so no worries about future VCS prods.

JAC: Add your prod :)

I fell from my chair when I saw it at sv2k11 compo. This rocks.

@Tjoppen: I've been trying to record the video since 2 hours. My new §%$&§ laptop does not support recoding from speakers (Win 64) and I AM GOING MAD

Awful music (sorry!) but nice effects.

One-ups our effects, nice to see technical progression!

Well done.
Music could be better :)

Cool effects. And horrible music. :D

nice stuff, and thanx for the source, which comes in handy as an aspiring VCS coder

Nitro/Black Sun: What framebuffer? This is the VCS - everything must be done on a line-by-line basis :)

cruzer: Yeah, that was actually the idea. I'm looking forward to more prods :>

I'll post the summary of how the effects work I posted at AtariAge here as well:

Text scroller: Just a frame buffer drawn using an asymmetric playfield
Twister: Mostly tables and clever use of the priority flag in CTRLPF. HMxx values are computed on the fly
Rotozoomer: A one-line buffer (two bytes, GRP0/GRP1) computed on the fly, x and y coords accumulate dx and dy respectively and are compared. The carries are ROLed in to form each pixel. Optimization could have allowed 24 horizontal pixels I think
Plasma: In each line, look up leftmost pixel in table and stick in COLUBK, then do 10x ADC #Imm + STA COLUBK, where the #Imms are modified during VBLANK (self-modifying code). Stagger and interlace for 22 horizontal samples
Pinwheel: 768 bytes of bitmap data form eight frames of one quadrant of the shape, mirrored horizontally and vertically (sort of). The few cycles left over were enough for the greet graphics

Horrible, horrible music - sorry. ;) But the effects are very nice, I especially like the plasma. I actually prefer this kind of full screen plasma over more accurate plasma effects that are fullscreen but have ugly black gaps between pixels. (Although I like my non-fullscreen plasma even better :p).

Text with drop shadows was a nice touch, too. :)

Except for the music, top notch!
