[ Echtzeit – Digitale Kultur ] CYBERDELIA – C64 Demo Maker Weekend

On November 28-29 2026, as part of the event series CYBERDELIA, and neatly at the same time as Transmission64 demoparty, we invite you to the space of Odenwilusenz in Beringen!

You already have some programming experience, but are curious to code closer to the metal and create effects for the C64? You want to dust off your good old assembly knowledge amongst like-minded people, and dip your toe into the still-kicking Demoscene?

Or would you just like to have some fun with the C64 and try out stuff, to use your knowledge later in other hardware- or retro-projects?

Just come on over, we love to have you! Please sign up beforehand under the link below.

Program :

• Saturday, 10 am: Opening, brief introduction of participants, mentors and helpers, overview of hardware, tools and potential projects. Afterwards free tinkering with experienced mentors and resources by demosceners
• Saturday, starting 4 pm: Livestream: Transmission64 Online-Demoparty
• Sunday, starting11 am: breakfast and informal show-and-tell

Venue: Odenwilusenz, Hardmorgenweg 21, 8222 Beringen ( Directions, German)

Admission Fee: free of charge, recommended donation of 40 CHF (in advance via bank transfer, or cash on site)

Registration (mandatory): https://nextcloud.ezdk.org/index.php/apps/forms/s/gZNZsNLWJeDBD9psL7Z2FzoW

Contact: shana (at) echtzeitkultur (dot) org

42Bastian keeps improving his Atari Jaguar engine. Another WIP showcasing video recording has been published featuring lovely Virgill Hively tracker music, so what can go wrong entering this 3D world for a moment?

 

[ Atariscne.org - News ] Updated SDL ports: OpenTyrian, HHeretic and HHexen

Back in 2010, when I released my HHeretic/HHexen for the first time (!), I had a dream: to be able to play those two games (and others: Doom, Duke Nukem 3D, ...) while listening to their great MIDI soundtracks. I knew next to nothing how MIDI works, how MIDI synthesis works, I only knew there is something called Timidity and that it is slow.

So for all those years I'd wished that somebody would create "something" to move this further.   A few years ago I purchased the great mt32-pi (which ended its development in a rather sad way...) for listening to ScummVM games' music (which I wholeheartedly recommend!) but it took me another couple of years to connect the dots: many of those SDL ports still had support for MIDI and even better, they often did it in an uniform way, via SDL_mixer! So that was only a "small" step to actually implement a native Atari MIDI driver there, link everything together and voila. HHeretic and HHexen got their music (same as did PMDoom, PMHeretic and PMHexen, btw).   OpenTyrian, that was another story: just a quick port, never heard of that game in 2010, almost a "./configure && make" job, done. Over time there were newer ports by insane/.tSCc. and medmed on AF but always from the stale sdl1 branch (2020; EDIT: In the meantime my pull request has been accepted!). So I didn't feel the need to update my own port (unlike HHeretic/HHexen which got updated in 2024).   Until now - I managed to backport all non-SDL2 commits from master back to the sdl1 branch so we've got all the cool improvements and bugfixes. I even optimised audio playback a bit, so the OPL emulation is almost usable on 68060@66 MHz (FireBee should shine). And yes, I do know about NokturnFM project, everything at the right time. :)   Those who know me are aware that I don't care very much about making quick SDL ports just for the sake of releasing something. I can promise you that these three projects have been extensively tested and thanks to them SDL contains tens of bugfixes and improvements.   So enjoy, play test and feel free to report any bugs. Currently I'm not aware of any SDL issues, the executables should fully work in GEM (window/fullscreen) and XBIOS (fullscreen), on all Atari machines with >= 8bpp output.

[ Echtzeit – Digitale Kultur ] Report: Graffathon 2026 – Coding becomes Art

The 2026 Bern Graffathon took place in a special atmosphere, namely in the premises of an art studio where primarily visual art is produced. «Coding goes Art» was the motto of this edition, which was very fitting for the location. The idea of bringing coding and art together in a new edition of the Bern Graffathon came up about a year ago and was enthusiastically supported by Echtzeit.

Once a good part of the 14 participants had arrived, we spent the day clarifying needs and offering technical solutions or support as they arose.

Tools available included a RaspberryPi, modern Linux laptops, a MIDI keyboard, and a graphics tablet. A curated library of books on topics such as generative art, graphics, mathematics, coding, street art, 8-bit retro culture, and more was available for all to use.

We invited people for a tour of the studio and showed the first floor and the artists who were working there in their small and larger studios, as well as their work to the interested Graffers. On the top floor, in the middle of the small urban garden, Moovie was able to set up his analogue camera to take a fun group photo.

The sunny terrace then provided a cosy spot for a relaxing lunch break. Refreshed and inspired by conversations, most people went back to their keyboards in the afternoon to continue working creatively.

In the afternoon, it was time to take a look at the exciting Xenium demoparty in Łódź, Poland, while working. A deadline was set for 7 p.m., but we were distracted from the final sprint by the welcome and delicious pizzas.

After all the demos were completed, there was a short review round and the audience favourites were determined by voting. Among them was an artist from the studio who looked at our demos from her perspective and was able to ask some unexpected questions to the hackers.

Unfortunately, the voting was not spared from glitches. Nevertheless, here are the final winners who were able to claim a sponsored prize:
