Event id #3008 : Intro Creation Competition 2020
Preface: Please use this thread for questions, discussion and everything else concerning this competition.
Again several people were asking about the competition being held this year. Especially during Corona restrictions people need something to spend their time. ;-)
As the 4k category was very successful last year for the cost of 16k entries, I had a little discussion thread here about using that category again.
ICC 2020 with 16k & 4k or 16k only again?
The majority there wanted to have 4k category again, so it's in.
I delayed the start of the compo a bit because some other compos were running I did not want to disturb.
But finally here here you go...
Competition runs from December 10th, 2020, until February 14th, 2021. So you have a good 2 months to deliver your creations. This should be enough for an intro.
RULES for both categories:
Your intro entry...
- has to work on a plain stock C64 (PAL standard) without any extensions.
- has to be a one-part intro. Short fade-ins and fade-outs are OK.
- has to contain at least one Logo at whatever size you like.
- has to contain a changing or moving text message (e.g. scrolling text, different lines fading in & out, etc.)
- has to be interruptable any time by pressing SPACE-key (exception are the short fade-in and fade-out).
- does not need to have exclusive graphics, charsets or music. But the code should be exclusive, so reuse of existing code with just exchanged graphics and music is not allowed.
- has not been publicly used before entering the competition.
- has to be handed in as executable format startable with RUN (.prg or embedded in .t64 or .d64).
Your 16kB intro...
- has a maximum RAM footprint of $4000 bytes at one block, at whatever location you like. Screen RAM counts as used memory. Exclusions are system addresses like VIC (inkl. Color RAM), SID, CIA, Stack, Zero-page, IRQ vectors. This means RAM besides chosen $4000 bytes area and exceptions has to be the same before and after running the intro. What happens during runtime is up to you.
- has to contain music (not just a humming sound, please).
- is linked to this competition as "C64 Demo" entry (sorry, no other fitting entry exists).
Your 4kB intro...
- has a maximum RAM footprint of $1000 bytes at one block, at whatever location you like. Screen RAM counts as used memory. Exclusions are system addresses like VIC (inkl. Color RAM), SID, CIA, Stack, Zero-page, IRQ vectors. This means RAM besides chosen $1000 bytes area and exceptions has to be the same before and after running the intro. What happens during runtime is up to you.
- does not have to contain any sound, but feel free to add some.
- is linked to this competition as "C64 4k Intro" entry.
You are allowed to enter maximum 3 entries per participant and category, so you can enter 6 entries at best. Entries might be taken back from the compo until deadline. That means if you want to remove one of your works from the compo to make space for another entry from you, this can be done until deadline.
Deadline for entry submission is Sunday February 14th, 2021 at 23:59:59 (11:59:59 pm) CET.
Voting closes at Sunday Febuary 21th, 2020 at 23:59:59 (11:59:59 pm) CET.
Voting platform is CSDb (with all disadvantages it may have), therefore entries have to be posted here.
Entries will be ranked by weighted average of CSDb votes. Entries with the same weighted average are ranked by their percentages of 10s, 9s, etc.
No prices to win, just the fame. May the best creation win! |

- has a maximum RAM footprint of $1000 bytes at one block, at whatever location you like. Screen RAM counts as used memory. Exclusions are system addresses like VIC (inkl. Color RAM), SID, CIA, Stack, Zero-page, IRQ vectors. This means RAM besides chosen $1000 bytes area and exceptions has to be the same before and after running the intro. What happens during runtime is up to you. So, if i get this right, $0000..$01ff does not count, neither does anything $dxxx in IO space.
The "IRQ vectors" bit is referring to $fffa/b and $fffe/f, i guess, but does it also include $0314..$0319? Do all the other system vectors or anything else in lowmem ($0200..$03ff) count?
(Note that the system vectors can be reset to default by calling INITV = $e453 and RESTOR = $ff8a, which is what the link glue code running the payload would probably do anyways.)
In other words, would an intro sitting at $0801..$13ff (with the payload at $1400..$fff9) having its screen at $0400 (thus 4K at $0400..$13ff) and leaving $0000..$03ff in an undefined state after pressing space be okay according to the rules?

I was asking for clarification on the "IRQ vectors" part, not discussing or questioning the rules as they are. |

The way I read the rules you can use $0314-$0319 without restoring. Not sure how you're gonna squeeze a sprite or so in that ;) |

Quoting Oswalddont feed the troll. Says the guy who repeats the rule verbatim without adding any clarification whatsoever. :) |

thats a misunderstanding due to my bad quoting skills and lazyness, I was sending that to your question if $0000-$03ff may be in undefined state. it may be not according to that sentence in the rule. you can only touch the (irq) vectors. |

Yes, it’s pretty clear that the only ambiguity is about $0314-$0319; the rest of $200-$3ff is obviously untouchable without including it in your nominated 4k. |

So... when nominating $0200..$11ff as my 4K playground, everything is fine and $0000..$11ff can be left undefined after pressing space? (y/n) |
