The part with all the borders open, and the 4 sprites on top .. I puzzled on it for a few minutes. "Why the alternate lines?", I thought. The D021 "clue" below doesn't help at all actually.
The trick: only 4 sprites are used for the scroller (of course). 4 sprites for the background. The full screen width is covered by alternating the x-coordinates of the 4 sprites on each rasterline.
It's "halfway" to being FLESCO. FLESCO of course moves 8 sprites on alternate lines .. this one only moves 4 (moving the scroller sprites is done once per frame rather than per raster-line).
Nice trick, though, and very very good for the time that this was released. Clever!
nb. to see more clearly, in VICE:-

| edit: not so sure anymore. But something similar could at least be done using d010 only. |

| @oswald: I'd think it's possible using only one register ;) |

| nice hint, I still dont get how its done tho :) is there enough time to rewrite 4 sprite x regs when opening border? probably :) |

This wowed me back then, but it's also still awesome today.
And nobody mentioned all the great music? |

The part feat. the large red: ECHO OF ONE WAY!!
moving back and forth into the side borders gives the impression more than 8 sprites are on a single line. |

| I love this demo... I know Ziz and Moppe but I never met Hound or Echo (that I know)... Strange they show up releasing one fantastic coder-pr0n demo and then vanishes... Anyone know who there are/were? |

| OMG! This demo kicks ass. Coding at its finest. I still remember how I was staring at the HOUND logo covering the border and still there were sprites scrolling over it... Of course also the vector part was amazing. And the last part... wow. Also remember it's just one file! |

| What monitor models? Only some jap TV sets avoid the PAL delay loop to avoid PAL patents. |

| monitors equally pal compliant not always :). actually, on my current c64+monitor it is completly solid, but on my previous one you could clearly see that it was stippled. |

| @Ben: Turn on PAL emulation and I hope YOU see the light. The effect is based on the PAL decoder and requires two colors with the same luminance. If you watch the demo on a real C64 or an emulator with PAL emu, the sprites cover EVERY rasterline and not every 2nd line. |

| @alih: You obviously didn't watch this demo on a real C64 or on Vice with PAL emulation enabled, because then the sprites fill every rasterline, not just every 2nd. |

| Giving this a 6 surely is downvoting, it contains some really amazing pieces of code. |
User Comment
Submitted by CreaMD on 2 August 2006
| Giving 6 isn't downvote. But you are right, it was downvote if it wasn't done without checking of the demo before judging. |

| Obviously someone didn't think this demo deserved a place among the top demos & downvoted it with a 6, what an utterly lame behaviour!!! |

This was one of the first demos that I saw which amazed me, and it's still one of my favourites to this day. For me, it's all about the oneway bobs :)
@Radiantx: Consider that there is only four sprites ever actually visible in the scroller part. Now look very closely at the logo, and the fact while every second line is skipped, on half of the letters it is the odd charecter, and on half of the letters it is the even charecter. It's a neat visual trick :) |

| Ok, I'm at a loss as to how that three colour scroller above the all-border spritelogo was made... Nice. :-) |

This is really a great demo, and it's in one file!
I remember first time I saw it - I got more and more impressed for every part. When the endpart was building up, I said to my friend who sat beside me (with much irony): "Now, the only thing missing is that those balls will start to move". And then they did! I was totally stunned :-)
