Event id #2889 : Intro Creation Competition 2019

Preface: Please use this thread for questions, discussion and everything else concerning this competition.


Many people were asking about the competition being held this year. It turned out to be a good place to have it after the big X party each second year. But why not give it a try in between?

This time I decided to add a second category to the well known rules: 4kB intro! It is different to the 4kB intro category you know from demo parties. There the executable file has the limit of 4096 bytes and may allocate as much as you like during runtime. Rules here only allow to use 4kB overall for a different challenge. Please check the rules for more details. Result will show if that was a good idea.

Here you go...


Competition runs from November 4th, 2019, until January 5th, 2020. So you have a full 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 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 are 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 January 5th, 2020 at 23:59:59 (11:59:59 pm) CET.
Voting closes at Sunday January 12th, 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!

I might be up for the compo, but pretty much busy at the moment. Although I do have an idea for an intro. :)

Noob question (as I am working on my first 'real' intro):
Should it be runnable from basic, so start at $0801? If memory footprint can't exceed 4/16K does that mean that it has te be from $0801-$1801 (Or $0801-$4801)?

No, you just have to stay within a $1000 or $4000 byte block of RAM somewhere in memory and, as long as all of the rules are met like including the screen RAM in that block, you get to choose where that is. Using a cruncher on your code means it can start from a BASIC RUN command - the startline provided by the cruncher - without you having to include a BASIC stub at $0801

translation: just use $4000-$8000 or wherever you like, and use a self extracting packer (cruncher) like exomizer, which will give you a runnable (0801) self ectracting prg.

OK, that's clear. Thanks

What can I say... I type 70 words per minute and some of them make sense. =-)

be aware RAM bank choice $4000-$7FFF makes a lot of sense if you do not need character ROM for a 16K but have a lot of gfx data such as fonts, sprites or whatever bitmaps. For 4K under the current restriction (RAM besides 4K must look same before and after running, $0400-$07E7 counts if used) chosen area shouldn't matter a great deal, anyway, unless you want to use CharROM (then $0000-$3FFF or $8000-$BFFF) might even be preferrable as you get up to 2 complete ROM fonts "for free"

best choice for a 4K: $0000-$10ff (cheat mode on) :)

You mean $0000-$11ff! xD stack doesn't count either ^^ Not to speak of I/O... sometimes helpful if things get really tight though in some cases these tricks mean more trouble than they're worth

Even $FFFE to $11FF should work with the rules as described.
