An der Demoszene interessiert aber während der #evoke2025 keine Zeit gehabt?
Morgen Abend um 20:00 Uhr gibt bei uns in der Heliosstraße eine ausführliche Zusammenfassung über die besten und verrücktesten Beiträge von der diesjährigen Evoke.
Wir freuen uns zusammen mit Tobi von @digitalekultur und euch auf einen gemütlichen Abend voller Demos, Hintergründe und tollen Geschichten!

#Evoke2025 was a blast! Always good to be back at #Evoke and meet old and new friends! #demoscene

COPPER SHOWDOWN was a hit and it looks like we will see much more from the FCK CPU activists in the future. 😉
Do you want to learn how to use the copper editor (by the Magnificent and Mighty @mop ), share techniques, ask questions and get encouragement? The Copper Showdown Discord is the friendly place to go!

the 'Shaderland' prototype got 3rd place at #evoke ! The same demo will be releasing on itch.io shortly.
I've had report of some problems with the Windows build on computers with integrated graphics, possibly due to cross-compilation on Linux. Once I've figured out what's causing the issue, I'll upload a fixed Windows build.
Thanks to @evoke for running a great party, see you next year~
💳 Important info about ticket payments
We’ve been made aware that in some rare cases, ticket payments via SumUp were accidentally charged twice. This happened when payments were flagged as failed at the infodesk and you were asked to try again.
If this happened to you, please check your credit card statement and get in touch with us at info@evoke.eu if you notice a duplicate charge.
We want to make sure that every case gets resolved and apologize deeply for the inconvenience.
Nothing beats the moment, when the stuff you have worked on finally runs on the bigscreen in front of an awesome community. Thanks #evoke, #demoscene. This was an amazing #demoparty weekend. #sciencedemo
BTW: the release is now up on https://www.pouet.net/prod.php?which=104778. At least for Linux. We are working on the macOS release, please be patient with us.
Greetings to all the nice people we met there and hung out with. Hope to see you again soon.
@Drehwerk That sticker gives you a glimpse on what you missed in the 46k compo block on macOS at #evoke.
We asked the beam team twice if the demo works „Yes, it works.“ We talked with beam team, that it would be a good idea to test it on external HDMI and make a screen recording, because it’s a new platform. The answer was: „We test it. Do we have your contact info? Go to your seat and we approach you if there are issues.“
We asked them twice, hours before the show. Next #revision
#evoke #macos Try to Download a macOS #sizecoding toochain. Good luck. It does not exist. We are probably the first group having mastered it. On the intel platform we used the upx compressor. If you run it on mac arm it says: „upx: DDE: CantPackException: macOS is currently not supported (try --force-macos)“
There is no demotools for that platform available! We did the whole tooling by ourselfes.
Evoke could have had three firsts. Drones, Copper, MacOS sizecoding. It’s a pitty.
#evoke A mac is kind of similar to Amiga. All macs of a particular generation are more or less the same hardware. It uses the same OS. The menu is on the top like in the AMIGA OS and they use custom chips.
If that entry works at my place, it will work in every arm mac. Without asking the users to buy a special GPU. If the chip is weaker, the demo does not run as smooth as we‘ve seen it. But it will run. So making a mac not running the demo properly is a way of mastery in itself.
3/3 #demoscene #evoke It was not the first mac entry where we had issues at the party. It looks like no one really want‘s to see mac os demos. It’s a windows world. Pouet lists 3 Mac categories: MacOS PPC, MacOS Intel and MacOS. The latest entry is on august 2018. There is (in total) about 500Mac prods. If you filter MacOS intel, it‘s about 300 prods. If you filter MacOS the number of entries is zero. At home it was testet on three Macs and with external HDMI. It works wirhout problems.
2/3 #evoke On the windows platform at the party the „Windows defender“ is disabled to run demos. On Mac os we have had the gatekepper turned on. We found a way to run the demo as sizecoding entry WITHOUT disabling the OS security mechanism! We added extra code so that the windows people can use the ESC-key (mac os users CMD+q). We added extra code to kill orphanned threads by a timer. We double checked with different computers. It was a well tested prod. And it works! See you at #revision 2026.
MacOS is using the Mach-O binary format. It’s the biggest binary container of all OSes because it’s made for dual assemblies. MacOS is no longer executing unsigned code. We used ad hoc codesigning. ARM CPUs want byte alignment. They want segments at specific addresses. All this is making sizecoding almost impossible. We found a way to create a 41kB demo with modern metal shader. We testet it on M1, M2, M3. Today with our external screen: It works!
#evoke you missed a sizecoding first timer. 1/3
I went to @evoke this weekend, and in addition to organizing the #pc #compos together with @juvi, I released a 4 kilobyte executable graphics together with Lila :) She named it "A Lost Soul". It won the second place! Here you go, enjoy!

I was part of this project, and what a fun one it was! It's the first Amiga demo I've contributed to in probably 25 years. And I cannot believe we won Alternative Platform at #evoke2025
Half a year ago, Blueberry started talking about doing a NoCPU demo to introduce a new compo category and somehow managed to talk me into joining the project. Actually, it wasn't that difficult. The NoCPU idea is obviously to make demos without using the CPU, only the Amiga's custom chipset. Way back when, I wrote this Protracker player for WinAMP called Oldsk00l, so I knew my way around the MOD format, and we would be needing a MOD player. It was really quite serendipitous -over the years I've thought a lot about how the custom chipset is Turing complete, and also wondering why exactly didn't we just compile a MOD to code, instead of interpreting it at runtime. It's basically just a list of instructions, right? Just compile it. So I got to implement this idea, which was hugely satisfying. Simply compiling a MOD to a huge copper list. It has to be the world's fastest MOD player, at least in terms of CPU usage. I mean, it seems unlikely that another player in the future might hand back the CPU more cycles than it spends playing the MOD. But never say never, I guess.
Other things I did were the interference effect, which I always wanted to try in this many bitplanes, the blitter tornado/chaos zoomer, which I hadn't implemented before, and the kaleidoscope effects.
Truthfully, Blueberry did all of the heavy lifting with his extensive framework for building copper and blitter instructions, handling memory allocation and reuse, and so forth. It almost made selfmodifying copperblits three levels deep trivial. His checkerboard and (perhaps surprisingly) the many, many transitions are really clever stuff. He made everything come together, and it is very much his demo.
