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!

been there, tried that. only problem is there are just few useful routines in ROMs and the most useful (KERNAL CLRSCR) fills ColRAM differently on older ROM revs. ATM I'm not desperate enough yet to seek through ROM listings *knocks on wood*.

of course some might use JSR $EA31 or better $EA81 to end IRQs

I found the float routines extremely helpful here and there. Especially POLYX ($e043). =)

As Zyron pointed out a while back, you can safely use
	lda #col
	sta $d021
	jsr $e536
on both old and new ROMs

Q: Must intro range cover $0801 ff or is a basic start/SYS line allowed without counting as used RAM?
If SYS-Line counts and $0801 ff must be part of my used RAM, I'm not in really big trouble but it would mean some more relocating work here which would make me go NARF...

Well last year for 16kb intro almost everyone (including me) used $4000 - $7fff. Packed with self extracting exomizer at $801 with basic line. It didn't count as used ram.

Expect a 4K PETSCII TND intro from me some time in December ;) I started on it today. I managed to create my own 1KB music player routine and started on the intro code. I should hopefully have it done within the next 2 or 3 weeks.

is it just me who thinks the 4K compo has more sex appeal than the 16K one? :)

Maybe, 4K really made me think and do some tricks I didn't think before. Cool exercise
