So last year at GEMTOS I was told by the French Atari sceners I should attend Revision and as such I decided to do so.
505...
A quick look at a number of things happening close together in a very short time.
Spring and summer seem to be the most intense period for demo parties and the releases that come with them. Plus there are a few stories which we could well miss, if we’re not careful.

The Outline timetable says: "12:00 GTFO or Help cleaning", so while Havoc and friends are swinging the broom, we can sip a cup of coffee and enjoy some party impressions and results.
A quick Outline overview, photos by Jade
Atari activity has been spotted!
42Bastian was hyperactive in the small size intro competitions with some nice screens: RTB, Fountain and Zini for Jaguar.
This Atari Jaguar 256 Bytro is utterly beautiful
First place in the oldschool 256 Byte category was taken by F#READY with an Atari 8-Bit entry called Flexus. Further, LX took part with Lynx releases in both the oldschool 128 Bytro and 256 Bytro compo, but no further information on those is available at the moment.
On ST we got three screens by Cortin, nice little contributions and partly looking really interesting.
On the Atari demo side of things we also had "YOFO", as a first release by Scion, a young group made of old people. Be aware that there is more to see than what is shown in the video capture. But this secret is left to reveal for real hardware warriors.
YOFO by Scion - The most orange ST demo so far
Then we got a couple of nice Atari ST graphics. Mysterious #592C63/akaikoshi striked back with a piece of his sticker collection and an additional anti-capitalistic motive. Steffest/Desire won the competition with an impressive and somewhat scary picture.

Dma-Sc and Doclands both were present and hold up the Atari chiptunes flag in the music compo, ranking 3rd and 5th place. These entries are not available yet, but will certainly pop up in the sndh archive. I remember some very nice and clean lead sounds in Dma-Sc's track on the stream.
The attendance is reported to have been a bit smaller sized this year, while the number of releases and particularly those of high quality went straight uphill in some categories.
As a small but painful step outside the Atari box:
The new school demos were really remarkable and packed. There was about a handful of entries which seemed to be the clear compo highlight, but the show went on and on. Among others, groups like Guidline or GDA were having their comebacks. And Majestetic released a nice homage to the 2000s PC demoscene spirit.
First place went to "Kablam!" by Trepaan which was a complete detective movie like experience, and entirely atmospheric and beautiful. Haujobb delivered a very uplifting fantasy console demo which also represents this year's Evoke invitation and features the new scene standard of unreadable greetings. The vibrant and funky soundtrack by Jazz was also winning the music competition at Outline.
If I would have to pick a favourite, that would be "Human Kaleidoskope" by Teadrinker. An absolutely gallant demo production, playing with one's imagination, accompanied by a really, really, really good soundtrack :-)
As far as I can judge, I think this has been the most comprehensive newschool demo competition at any Outline so far.
But let's not stretch the Atarians attention span any further with those side roads. Have a look at all the releases on the respective pages, if you like.
Thanks to spkr and Jade for sharing a few of their insights for this article!

← Fixing Post-Increment Addressing
DBRA and the Cost Model Balancing Act
When you write assembly for the m68k, dbra is just there. Put your count in a data register, end your loop with dbra dN,.label. Four bytes, twelve cycles per iteration on 68000, no flag dance, no comparison. Your loops naturally form around the instruction.
C/C++ does not work that way. The natural loop in C is for (i = 0; i < N; i++) or while (cond). Neither says "count down and exit when you wrap", well, while can. But a counted-up loop with an unsigned comparison is what the language naturally models, and that is what GIMPLE mostly produces. Turning that into a dbra is a backend job, and requires carefully written code. And GCC, for reasons we will get to, mostly stopped doing it for m68k.

Chipo Django 3 is now available in its final version.
There were reports of a buggy replay, so I took apart the Lance replayer once again and (hopefully) fixed every known issue. This new version now runs the latest version of the ProTracker Replay 2.3f by 8bitbubsy using the Lance Paula emulation. (Both the Acorn and Amiga side also had some different bugs fixed)
The replayer source code is available here.
And special Thanks to evil for recording both the party and final version for youtube!

The second big game release over these past days. This one has been pending for absolutely ages. Return to Blacktooth, aka Head Over Heels 2 has been released by Thalamus Digital Publishing.
I remember writing something about this, over a decade ago. Colin Porch, the programmer, started this when he was still at Ocean Software, but this was not taken up by them. He was showing it around at various computer shows. The new game having over 300 rooms to explore and brand new puzzles in the classic old school isometric format.
Many years later, this has found its way to Thalamus Digital Publishing, with a digital release on the 4th May 2026 and a physical release to follow later.
You can find out more by following this link - https://thalamusdigital.itch.io/return-to-blacktooth-atarist - A purchasable download to enjoy this game should be available from the 4th May 2026.

Some *big* game news for the Atari ST this weekend, as Miracle Boy in Dragon Land has finally dropped after four years of work.
(From the website) - "Miracle Boy in Dragon Land offers a magical adventure across 25 levels, combining exploration, puzzles, mini-games, and equipment upgrades. The player takes on the role of Paolo, tasked with freeing the kingdom from the clutches of the evil Count Drago in a universe inspired by the classic Wonder Boy in Monster World."
We have Samuel Blanchard and DMA-SC to thank for this marvel.
It is very ambitious in scope, stretching the ST’s boundaries hard. A 1MB ST is your ticket to ride!
You can find out more here - You can purchase a digital copy and there are a decreasing amount of physical copies available.

SV 2016
It’s another Sillyventure past times report. Another one that remained hidden in the archives until now. This one was mostly made, as it happened.
It was a pretty faithful diary of my alcohol consumption and state of intestinal health during that period. Oh, and quite a few party happenings as well.
I liked my writing from that period, seemed to be livelier back then and less, tired, than more recent efforts.

#This bit is not in realtime!#
Good morning, evening, or dead of night, whenever you are reading this new Maggie issue. This is the official CiH authored realtime party report, with non-realtime later on additions, for the eagerly anticipated Sillyventure 2016 party. (Not to be confused with the realtime article, which is an entirely separate document created by a lot of people, sometimes in co-ordination with their fingers and brains, but often not!)
So is this going to be another party of our dreams, or a never-ending silicon nightmare? Well read on and discover.

exxos has released version 3.03 of nrvpack, a free online executable compression service for Atari ST PRG/APP/TOS/TTP files. Upload a file and get five compressed variants to choose from, each with different size/speed tradeoffs.
The packer and all 68000 decompression stubs were written from the ground up using AI. Months of development went into the compression engine — including optimal parsing with dynamic programming, lit-cost sweeps, context-width tuning, and extensive testing of preprocessing transforms and encoding strategies to squeeze every last byte out of typical 68k executables.
On large real-world programs the best format achieves around 2.75:1 compression ratio. A fast-depack option is also available that decompresses in under a second on a stock 8MHz 68000. All formats support colour-cycling raster bars during decompression and run on any ST/STE/TT/Falcon.
The service is free and requires an exxos forum login.

kallebl0mquist published a ChatGPT Client for the Atari ST, so also modern and hip work environments can be migrated to the Atari platform.
Dumbing down with class, using this seductive keyboard
(Picture by kallebl0mquist)
From Github:
I have been building a GEM-based LLM chat client for the Atari ST in GFA BASIC 3.5E. What if an Atari ST could talk to a modern LLM? Not a fake retro skin in a browser, no emulator (though I love Hatari!), but my actual old Atari Mega STE. GFA BASIC was developed by Frank Ostrowski in 1986 and was hugely popular among ST users at the time. So I chose it in the hope that there might be still some resources out there. Did I learn GFA Basic properly for this project? No, but i dug out all the old docs and books and forced codex to learn it. Ha,ha. Poor thing.
The setup :
- Atari Mega STE in high-res monochrome
- GFA BASIC 3.5E on the Atari side
- Raspberry Pi and python 3.12 on the other side
- Nullmodem serial cable (StarTech 30cm USB Nullmodem Seriell Adapterkabel, USB-A auf RS232 DB9)

Given the current developments in the scene and the impending loss of the
host 'untergrund.net', I have decided to accept an offer from the Echtzeit
association and we have moved the entire archive to a new server.
You can now find the Fujiology archive here:
Big thanks goes to Echtzeit (Psykon and Unlock) for their fast help.
Watch out if you still have links to 'untergrund.net'... they might
be gone soon.

After six months, Michal has released a new version of his FreeMiNT distribution for 32-bit Atari computers.
This release uses the HDDriver demo as its disk driver, with Uwe providing a special version specifically for the distribution.
A notable new addition is stool, a MiNT tool that replaces the uiptool utility known from TOS. It provides web-based access to Atari disks.
All included GEM/TOS tools are now stored on the GEMDOS C: partition. The distribution also features an experimental 060 kernel, improved SCSI write support, RAW access through devfs, and plenty of other improvements.
The image is available on GitHub.

← Register Allocation and the Cost Model
Fixing Post-Increment Addressing
Some years after high school, me and AiO worked at the same company for a while. I spent a lot of time at his apartment in Vimmerby, watching demos on my Falcon030 and his accelerated Amiga, playing Elite Frontier, and making grand plans for projects that mostly never shipped. I was going to write a Worms clone called Grubs, built around fractal-generated terrain and a neat paralax scrolling trick. In the end the only game released from that apartment was DB Phone Home, a 4K side-scrolling platformer for the Falcon. But the thing I remember most is reading AiO's copy of the MC68060 User's Manual.
The 68060 can not only do a multiply in two clockcycles, but execute two instructions at once!? Motorola called it superscalar, and I thought it was the most exciting thing in the world. I imagined what an Atari with this beast could do, and where the 68070 would take this — even wider issue, more parallelism, the same trajectory the industry was already on with the Pentium and the PowerPC. Of course, the 68070 never came. ColdFire does not quite count for me. Our beloved CPU family ended with the 68060, and the dream of wider superscalar m68k died with it.
But the industry kept going. GCC optimizes for that dream-made-real on other architectures: x86-64, ARM, RISC-V. Independent instructions that hardware can overlap or even reorder to execute over half a dozen instructions per cycle on for example an Apple Silicon M3/M4. This all works, as long as there are no data dependencies between consecutive operations. And this is where it goes wrong for us.
