Works for me in Vice 3.4 (GTK3, True Drive Emulation turned on).
Nice demo with awesome loader (interesting story). I like how it starts. |

LFT is a very complete C64 artist: code, music, gfx, even loader. He feels at home in all departments.
Lunatico is some of his finest work, but I love this one too. |

Great demo, surreal loader.
I loved the totally fluid and fast chessboard part the best. |

I just read the article about the loader. Even if i'm not into loaders that much, i knew the limitation and I've never considered that was possible. Amazing work!
When it comes to demo itself, I also enjoyed the effects and the demo flow. It's very admirable how you expertised on C64 hardware so quickly. But on the other hand, it shouldn't be so hard for someone who is capable of designing his own hardware and making a demo on it. ;) |

Axis: Fully decoding (and checksumming) a standard GCR-encoded disk block on the fly is one of the holy grails of C-64 coding, kind of like full-screen full-res 50 fps rotating vector cubes.
As the data flies by the head, you want to use the cycles normally needed for waiting more effectively to decode and checksum ALL the data. Until now, this hasn't been achieved (and still isn't if you really regard on-the-fly checksumming while reading as important - Lft niftily solved this by checksumming after transfer, which is a smart idea when it comes to loads of party static, also relieves the drive from the burden of checksumming).
So there was always an extra loop after reading to fully decode and checksum everything, effectively costing you a revolution per track. The 1570/71 drives are one rev faster than 1541 on my loader thanks to their 2 MHz mode.
We could move this topic over to some thread if anybody's interested in some details. |

realtime uncrunching i suppose, the flow is very smooth in the demo.

I'm impressed, finally somebody managed to fully decode a block on the fly. Why o why didn't i try hard enough? :)
A quick glance at the code revealed: Because of quite a few sacrifices i have always been shying away from, like dropping all the overhead needed for filename-based loading in favour of big (in the 2 kB drive world) tables, and also having C64-side tables which would violate my $0100-bytes-in-minimum-configuration rule, not to speak of being drive-type agnostic and friendly to disabled true drive emulation.
Still an amazing feat. Hats off to you, good sir! |
