Zoo 2019

Some recollections from my participation at the Commodore 64-only demoparty, Zoo, held at Akaa during 4th-6th of October. Again, not really a party report, I'm mostly talking about my own works.

Not the general theme of the weekend.

My pre-party mood was a bit pessimistic, after not catching a hotel room. Another thing I worried about a bit was not having any prods for the compos by the time I arrived. But I managed, as usual, do something on the spot.

It turned out the common accommodation at the nearby building was much better than I expected. The airbeds are cozy and the space was not jam-packed. It actually has a few pros compared to the hotel room, mainly it is very silent (the party noise won't reach there) but it's also cheap. If only I hadn't forgotten to pack the roll-up bed...

The unsuspecting Viiala neighbourhood, somewhere in Finland.

SID

SID was a general theme of the event. Grue gave an overall 'mythbusting' session about the SID and played concrete examples of playing the same songs on different SIDs. The differences were quite drastic, in some cases the wrong SID can even hide the lead instrument.

The bottom line is there is no overall 'best SID', some songs sound better on the 6581 and some better on 8580 - not even always the one the author intended! Your ears be the judge.

Flex gave a workshop on Goattracker. It's a complex piece of software, and SID is complex, so I doubt anyone could have started up Goattracker there and then and gotten finished results, but as I had at least some previous experience I could pick up one or two new things.

I mused that to be able to do SID music on C64, you have to have an understanding of many things, not just one thing:

• About SID features, behaviour and constraints
• The convention of "a SID" as a tracked format on Commodore 64
• How Goattracker (or some other editor) works

And maybe some musical knowledge too. Well, anyway, these SID presentations encouraged me to think that it does not matter so much if I don't achieve the perfect iconic SID sound, so I started tinkering on a crappy tune following some of Flex's tips.


VIC-II

Dr. TerrorZ: Light

I had a Multipaint presentation, but I found I couldn't really 'teach' anything at this point so I simply told what the program is for and showed the main features of the new version. This led me to have chit-chats with various sceners which was maybe the best outcome of the presentation.

The software is now already quite known in the scene but not everyone will adopt it. But I don't think I'm bragging if I say it is a good introductory-level software for making C64 graphics!

First time i saw the zoo from this angle.

My graphics entries were even less successful at the compos than last time.

Normally parties tend to go so that I pick a half-decent half-completed image from the archives and finish it, but this time my folder was rather empty. I also spent a lot of time getting a demo production working (see further below), time taken away from drawing.

The bitmap work was a quick experiment with drawing using wacom tablet with Multipaint.

Dr. TerrorZ: Spacesplash

I preferred the initial quick lines and was even afraid to lose them with too much detailing. So I actually like this image quite a lot (perhaps because I did not have time to grow tired of it) but it didn't go down that well in the compo.

Admittedly, a further session would have helped it a bit. (That's a damn long arm!)


CPU

I was greatly impressed with the amount of quality demos at Zoo. I recall the dry year 2013 when even a crappy PETSCII demo written in c by some idiots could win.

The Finnish Gold 'returning' with a full-size demo should/could have been a bit more grandiose. Although it was presented at the show-stealer last position, it was a bit on the short size and petered out in the end. Artline Designs demo Out of Contex delivered better overall and was the clear deserved winner. The Void Mind was still incomplete at the party but is clearly a memorable demo. PWP's Metadimension was an atmospheric generative-algorithmic work.

In the drunken tired atmosphere there was a tangible mood of having passed a turning point and a feeling of living amidst a new rise of the Finnish C64 demoscene. In a more sober hindsight, it's perhaps not all there yet... X'2020 will mark the spot.

I submitted my modest Nine Rings one-filer, based largely on re-writing Digiloi game routines. Digiloi object drawing system is naive in that it draws characters and colours separately to two buffers, and only combines them at the screen. Now I have the graphics stored in a reverse interleaved order for the drawing, and the buffer is also interleaved. So I could have 9 Digiloi-style 'sprites' on screen.

From Dr. TerrorZ: Nine Rings

The PETSCII mode is forgiving in that I can go with 1/3 framerate and it still looks kind of acceptable. The routine was in place before Friday but I did the scripting, music and some additional graphics at the partyplace.

After hitting the ring theme, my goal was to visualize the One Ring to Rule them all... poem, giving an outline to the demo script. But as time ran out I could not add more graphics and it was left more abstract. It was well enough received.


I/O

Apart from the above presentation, Kasettilamerit made an appearance, and the bid for making demoscene a part of UNESCO World Heritage was also presented here.

At the location I bought an external kernal replacement cartridge, a REX 9628 clone. Equipped with JiffyDOS and JaffyDOS and other jibba-jabba, I'm hoping it will make an interesting companion to SD2IEC or that Raspberry floppy emulator. More about these later.

Also I got a K&A paper magazine English edition with a Digiloi review :)
