When you're talking on a demoparty to people that left the scene for some time and they ask you with their big, sad, brown...
The Atari ST demo "Motus" was released in 2019 by SMFX. Back then it required 2 MB of RAM to run the demo.
spkr has reworked the code and memory handling so the demo is now working on a bog-standard Atari ST with 1 MB of RAM from a floppy disk.
Rumours say a couple of floppy disks with the demo on it are available on demand.

The mysterious faulty DMA-chip in Atari STE has been matter of research from different sides. While many investigations resulted in the advice, to replace the DMA-chip by a "good" one, e.g. Czietz (chzsoft) has investigated into another direction and found that the problem may be solved in software instead. Further analysis of the different chips showed, that if the software driver part handles some edge cases differently, the chip works as it should!
Some nebulous guys picked up the theory and patched the famous and still developed HD driver by Dr. Uwe Seimet. The patch is not related to the product and to be used at own risk, obviously. However, if this proves to be true, we could see an end to the unfortunate "bad DMA-chip" tragedies resulting in massive data loss (talking straight from the horse's mouth).
The patch is accompanied by a lovely STE intro released at last Sommarhack.

A pretty unexpected sign of life comes from long lasting company THALAMUS. Surprisingly they are are still alive and it seems they are also focusing the retro-market.
It seems that original author Colin Porch was working on a sequel to 'Head over Heels' for years and it is coming to Amiga and Atari ST in 2025.

The new Atari ST version of the wonderful classic "Yoomp" by Dekadence is now subject to the current round of the "ST Offline Tournament" (STOT) - a monthly gaming competition being held on a monthly base on Atari-forum.com. The tournament rules can be summarized simply as: use your beloved ST (or emulator for the bad boys) to play a selected ST game in a fair but competitive surrounding, take photos of your CRT with the highscore and post them in the respective forum thread. The game is played for a month and the STOT organizer, Thorn, is managing the score table in the forum thread. Thanks for all this at this point! :-)
STOT is running since 2007 but fell in a slight winter sleep the past years. It's really refreshing to see a revival of the tournament with up to 11 participants in the last rounds. Sometimes game developers themselves adopt their games for the tournament or take part playing even (e.g. with Randominer, Faster or Chroma Grid). But no worries, if they are too good, they get disqualified ;) However, the format is a really nice opportunity to test and play new games and unknown classics and enjoy using the real hardware with others. Feel free to join the common experience of STOT anytime!
Currently chronicthehedhog leads the Yoomp excess with crazy 3.471 points, followed by wietze with 3.115 points. But we still have about two weeks to go.

Those of us that have not been present at last Sommarhack party might have missed Ggn's new Friday night show.
But you can still enjoy it online 2 Fridays later!
In the video a number of Atari games are presented that were actually written by Atari demosceners, great idea! The video has been recorded on real hardware (Mega ST, Mega STE and Falcon) and features slides with additional information on the games. Be prepared for some surprises!

Hard to believe, but the FPGA-based Suska-board project is running for 20 years now. Feels like yesterday, that news on the project was spread the first time. I find it impressive, how Wolfgang Förster kept on working more or less continuously on it all the time and apparently, there are still new developments being made:
"The Suska-IV-B hardware is, of course, only as good as its FPGA core – the modeling within the FPGA. And we had something special in mind: it was meant to be a Falcon, and it became a Falcon+. Unlike the original, however, it features 48MB ALTRAM, 14MB RAM, a 32-bit data bus, a USB subsystem, Wi-Fi capability via PicoWIFI, an HDMI video interface, and various expansion options."
State of the Suska presented on their website
As shown, the Falcon modelling is advanced. However the DSP is still missing, but is being worked on, according to the Suska creators.
While we can expect that the final product will be for sale, there is also Zerkman's free and open source zeST project offering a ST clone on very cheap low end FPGA-hardware.

GliGli has created a patch for gwEm's well-established ymVST plugin for Digital Audio Workstations. Apparently a special feature has been asked for (well, by GliGli himself) so he just implemented it straight away. The author describes:
"it takes a MIDI file (exported from the DAW, from a project where ymVST was solely used), and a bunch of patch exports from ymVST, and makes a VGM or SNDH file out of it."

A new point and click adventure game was released today for the Atari ST.
Features of the game (snipped from the games website):
- A no-budget Lucasarts style point&click gameplay
- NOT a Sierra style point&click: no death, no softlock (hopefully)
- 2 languages (english or french)
- A little more than 100 screens!
- A little less than 20 different musics!
- Precisely 26 digitized sound effects (STE or F030 required)
- Only one ending
Animated gif image from the itch.io site
The game works on a regular Atari 520 ST, but requires a harddrive with at least 2.5 MB free space. STe and Falcon users get to enjoy digitized audio as well.

As you may have noticed Tat/Avena and Damo/RG have released a new demo last weekend.
There are many things to say about this wonderwork. But even better when the creators themselves speak up and explain what they did there! Tat just published an article about the technical background of the production and his take on the "curl-noise" on his blog.

The demoparty train keeps on rolling and the fellows of Ephidrena are currently visiting Black Valley demoparty in Norway, after having released their long awaited STE music demo "YMSE" just last weekend at Sommarhack.
A few Atarians and STEs are present and rumours say even an Atari release was in the works for Black Valley too, but cancelled due to rightly giving the social experience priority.

Retro books (or books about retro subjects) - everyone does it these days, you can find a ton of them around from self publishing houses. Usually good print quality and format, contents most of the times so-so, written by enthusiasts who aren't really good reporters or writers.
Instead, how about reading one of the first ones?
Halcyon Days: Interviews with Classic Computer and Video Game Programmers was released back in 1997, as a bunch of HTML files in disk format, priced at $20 per copy. Its author, James Hague, an 80s programmer himself, idolised the people featured in the book, therefore he took good care in making interesting conversations which he then transcribed to the book. And, to our delight, a lot of them were using Ataris!
Adam Billyard, Danielle Berry, Chris Crawford, David Fox, Steve Hales, Archer MacLean, Jeff Minter, Philip Price. And then coin-op legends like Eugene Jarvis, Ed Rotberg. And foreward by John Romero. How many of those so called "Retro Books" can present such a lineup?
Since then James has kindly released the book for free and is hosting it on his website for quite some time now. A recommended read, head over to https://dadgum.com/halcyon/ and enjoy!

Sommarhack, the legendary demo party that always felt just out of my reach. For years, I watched from the sidelines, thinking it was one of those events I’d never get the chance to attend. Then, unexpectedly earlier this year, an email from Spkr landed in my inbox. Suddenly, what once felt impossible started to feel real.
It wasn't an official invitation, but a spot on the reserve list. That was enough. I accepted immediately. Hope turned into anticipation. A few days later, another message came through. This time, it was confirmed. I had a place.
I'd heard from my Atari friends who'd attended previous Sommarhacks how amazing it was, and how much fun they'd had. Truth be told, I was always quite envious. But would it live up to my expectations? My imposter syndrome peaked, and I even had doubts about going... Ultimately, I bit the bullet and booked my tickets from London Gatwick to Stockholm, Sweden.
I was going to Sommarhack!

A quite interesting interview was recently published, where Tillmann Bubeck, the programmer of the 16 Bit home computing era classic "Rings of Medusa" is answering questions on his memories and the making of the game. Tilmann Bubeck is also known for demoscene contributions and especially the development of later Neochrome Master versions under the pseudonym Chaos Inc. of Delta Force.
Unfortunately there is no English translation. One particularly interesting story was about how he actually found a publisher:
He spent the last 1-2 school years with coding in a daily, second coding shift right after school and creating this game concept together with Gogo/Tex/Delta Force/TCB. The two in fact almost never met in person as they lived far apart and mostly relied on using phone for communication. The game idea was developed just basing on what they liked themselves and it's pretty amazing how this completely worked out in this case. When the game was finished, a publisher was to be found. The approach for them back then was not writing mails or using telephone, but simply visiting the Atari fair in Germany and go directly to the companies booths with a disk and the game on it. Quite crazy, but also very down to earth compared to todays complexity. Just imagine how a 19 year old teenager comes along a fair booth and says "hey, I have something, can I show it to you?", the publishers would load the DD disk on an ST and inspect the game. And how all this worked out in the end. In this case, it was Starbyte Software, and they were landing a hit just with that.
If you want, enjoy the whole interview in full length:
Thanks to Lotekstyle for the hint towards the interview!

Absolutely on the boundary of Atariscene-related content plus appreciatively taken from a post by Monsoft on the Polish Atari scene portal atariarea.krap.pl, this article might be of interest for a few. Is it? Is it not? Let us know!
And yes, apparently the good old silly season hole is kicking in. However, with Sommarhack and Sillyventure I am sure it will be not for long.

Apart from steady improvements and bugfixes, Guilliame has provided support for Apollo Vampire super-enhanced hardware. Needless to say it remains friendly to anything with a Fuji badge with a 68030 processor or above.
Some more features have been added as below:
Enhanced support for Psound card
Apollo Vampire Standelone V4+ supported !
Albums of videos
Tool to compute the real DMA frequencies
Enhanced files to add subtitles/comments
Internal tool to record Enhanced files
Pause available (Alt+Control)
There is a new revamped menu as well.
So if you like playing or disassembling movies on your Atari, head on over to Guilliame’s website at

When looking at the Avena listings on Pouet or Demozoo one could be forgiven for thinking the crew is more or less inactive compared to its late 1990s heyday.
In fact, nothing can be further from the truth and I wanted to draw Atariscne's attention to some of the latest under-the-radar content. Of course, we all remember Tat from landmark Falcon productions such as Sonolumineszenz or more recently the goalpost moving 44 (chapeau Tat!). In between his day job at Sony's elite advanced technology group Tat has been actively working on a number of Atari projects.
News and deep technical dives on these projects is available on what appears to be an anonymous blog, but is actually a gold mine of "the good stuff": results of his bleeding edge experiments.
Here are some particularly juicy articles which we'd like to draw your attention to:
A massive project Tat has been working on is an add-on for the Hatari emulator which adds features similar to the old Steem debugger. Sadly not officially part of Hatari, the debugger is almost a requirement for fixing certain bugs when developing under Hatari.
As someone who is fond of looking at disassemblies of other people's YM drivers, this is a very good starting point for understanding what you may see in Easy Rider when looking at YM drivers. It could even be some inspiration for writing your own!
I can say from personal experience that these notes describe 90% of the challenges you face if you want to create a multi-part 4K demo with music on the ST, or any platform. Tat takes things to another level though, in particular with his knowledge of packing.
Here Tat shares more of his coding articles and source code, including Falcon must-see Sonolumineszenz.
A covid lockdown project Tat worked on after being inspired by some chats with Damo and I. This is really low-level information and explains how and why you can get the YM and 68K to synchronise on a cycle level, essential for the sync square effect.
The fashions in ST demos have unfortunately returned to minimising CPU time used for the music. Using a dump of register writes to the soundchip might be a way to claw back some precious CPU cycles. On the other hand, such a register dump can be quite big. Tat presents a novel solution to this problem.

A huge project of re-creating the Atari Falcon custom chips has been going on for a while. Today Mikro with crew (including the veteran ST customchip decapper Ijor) released a presentation of the work done so far. For a noob like the article author this seems like black magic and absolutely impossible, truly fascinating!
The process of decapping and delayering the chips together with making very high-resolution photograps is quite expensive, and so far Mikro have funded the entire operation. Now it's possible to help the project by donating, which in the long run could help reproduce the Falcon chips to repair broken computers and building new ones from newly manufacturered motherboards.
