Event id #2757 : Intro Creation Competition 2018

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

After ChristopherJam had the chance to run a similar compo last year, this year I am back with the known ruleset, with only slight change.

Runnning the competition after X party turned out to be a great timeframe, so I stay there.

Competition runs from November 5th, 2018, until January 6th, 2019. So you have a full 2 months to deliver your creations. This should be enough for an intro.

Your intro...
- 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 contain music (not just a humming sound, please).
- 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 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).

Maximum 3 entries per participant. 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 6th, 2019 at 23:59:59 (11:59:59 pm) CET.
Voting closes at Sunday January 13th, 2019 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!

It's good to leave. I thought of using it, but didn't do any effects requiring that. FPP would be one.

Oswald: made for me possible to use an extra screen outside my bank

I thought it was illegal?! ;P

Finally, my intro for Intro Competition 2018 was released at Moonshine Dragons party together with this release:
The Great Escape 115%

The intro actually uses more than one RAM bank, so it would be disqualified anyway. But here you go!

It features a charmode logo and a hires scroll over a "transparent" layer with custom font that's also available to download (see comments in the release link).

Nice work, Digger!

I was about to ask why the scroll jumps four pixels every four frames, then realised it's highres 3 colours (fill/edge/transparent) over a two colour background.. and now I need to think some more :)

indeed nice puzzle, here is my guess:

-black outlines are bitmap
-font inner color expanded sprites
-checkerboard background must be adjusted so its always see trough if char color is in front

Yup, looking a bit more closely, every 4x1 cell in that area contains a mix of black outline pixels and a single background colour, where the background is either one of the two greys of the checkerboard or the current fill colour of the characters.

So, X expanded multicolour sprite underlay, with the fill colour plotted into it wherever required. Mode is probably capable of a three colour background or a couple of char colours too :)

@Oswald, @CJ: Thanks for kind words. You've solved the puzzle!

Yeah, the scroll "jumps" every 4px because of x-expanded sprites underlay:

Black outlines are actually drawn on double buffered circular chars – faster to rewrite than bitmap, although I have 4 frames to do that (otherwise the scroll would move too fast).

Buffer for sprite underlay is single and ROL'led by 2px (that gives 4px when x-expanded) and checkerboard colors are swapped – that makes the chessboard static (the area under the tools is flipped too).

It's possible to have an alternate font color (or even rasterbars) but I didn't have time to implement it, perhaps I will release an updated version.

It was fun, but quite tricky to do :)

Ooh, clever!
