What a Compiler Must Get Right (That You Don't)
When you write assembly, you know the context. You know which registers hold what, whether a pointer is aligned, whether the loop count fits in a word. You know because you put it there.
Consider a demo screen where you reserve a6 for the background rasters. You update the pointer in the VBL interrupt and just advance with a minimal (a6)+ in the HBL. All your other code simply does not touch a6, because you wrote all of it. Need to update a screen pointer? Just write the global. No function call, no overhead, no uncertainty.
A compiler has no such luxury. It must be correct for every possible input the language allows. It cannot "just know" that a pointer is word-aligned, or that two buffers never overlap, or that a register is free. It must prove it, or assume the worst. And not all code it calls may even have been compiled by it. Maybe it was built with an older compiler, a different language, or maybe you wrote it in assembly yourself.

The 10th edition of the Dutch Atari Meeting took place past weekend and judging by the photos available this was a great event for all Atari platforms.
According to wildly circulating rumours also some Atari sceners were present, some of them meeting as ripe men, decades after their previous encounter when they were fresh and young.

Some more old ‘new game’ news is heading our way.
This unexpected gift comes courtesy of Neil Rackett of Mesmotronic, who created the 3D model of an ST running in a browser window.
This time, he’s ported an ancient MS-DOS game ‘Sopwith’ to the ST.
It features intense biplane action through charmingly retro vector style graphics and arcade style gameplay, with characteristic MS-DOS beepy early PC sound. Interestingly, this game was going to get a dedicated ST version back in the day, but this did not happen, until now.
It can be downloaded from his Github repository. Good luck figuring out the controls!
CiH - 22.3.26.

This is a brain dump of what I have learned working with the GCC m68k backend, and maybe an attempt to convince someone else to try. This is the first of an unknown number of posts. No promises for how many there will be; I will continue as long as I have something to say and I find it fun.
I got my start with STOS Basic on an Atari 520STfm around 1990. Me and my classmate Tam formed T.O.Y.S. (Terror on Your ST) and I dubbed myself PeyloW. But in the scene, elite sceners wrote assembly; only lamers used STOS or GFA, every scroll text was clear about this. So we bought DevPac 2 and taught ourselves 68000 assembly, starting with snippets embedded in STOS and eventually graduating to full demo screens. The pattern that would follow me for decades was established early: high-level languages for tooling, assembly for anything that had to be fast. STOS gave way to PurePascal in the late '90s, but assembly remained the language that mattered — right through to the Falcon030 demo "Wait", released at EIL 2001.

Apparently, the Polish developer kTz from Retro Blitter Team known from his latest game Rogul is working on a STE enhanced version of Cannon Fodder, to finally catch up with the Am***.
The friends of the Polish Atariarea portal prepared this nice preview video
Atarimania also lists a WIP version already.

In order to encourage people to enter the Buxton Bytes sample demo showcase I am releasing the full source code to my entry way in advance of the event.
https://github.com/gwEm303/sample_demo
The demo will run on a 1MB STe from a 11 sector 82 track DSDD disk. It incorporates the Kalms ADPCM route, a sample sequencer and three alternative memory management schemes.
As an example, a version of Daft Punk's "One More Time" in mono with a hybrid 25/12kHz sample rate.
I attach an MSA file those who are not keen to assemble the source code may try.

PeyloW of T.O.Y.S. have been busy lately by optimizing the GNU C Compiler (GCC) v15.2 to create faster code for 68000 processor.
The improvements include using proper dbra/dbf loops, auto inc/dec of address registers (you know, the stuff that is nice on 68k!).
PeyloW writes in an Atari-Forum post:
At a very high level there are 7 groups of changes made:
-
Cost Model - More accurate cost models, allowing gcc to chose better.
-
Register Allocation – Adopt LRA, and tune to prefer fewer registers.
-
Loop Optimization – Adopt new doloop hooks to enable more explicit use of dbra.
-
Memory Access Reordering – More of cleanup pass for other optimisations, try to ensure memory access is sequential.
-
Autoincrement Optimization – Which allows more auto increment to be used instead of indexed addressing.
-
16/32-bit Optimization – And merging of 2x word accesses into single long access. Also narrow mulu/muls operators to word size if operand sizes can be determined at compile time.
-
Various Smaller Optimizations – Grab bag of stuff. Single bit extraction bit btst/tas, and simple peephole optimizations.
While working on GCC, PeyloW also developed a separate tool to count 68000 cycles out of assembler sourcecode to easily check if the compiler changes actually improve stuff - but can certainly can be very useful for other purposes as well.
Both projects can be found on Github, see links below.

The annual European Retro Computing Gathering "VCFe" will take place from 1st to 3rd of May 2026, in Munich, Germany. One focus this year are less present machines, the "Beasts of Burden", means more unknown working horses of the retro computer range. If that doesn't attract, keep in mind that may is also beer garden season.

A couple of years ago on Silly venture a music demo was released from a new group; Nutmeg Mine.
The demo may not be the best since sliced bread and we have wondered how the hell Silly Venture could run the demo on an ST as it requires more than 4MB of memory. Maybe they had a zeST?
Anyway, Caulky, the coder of Nutmeg Mine's "Scatman John" demo is now making an attempt to win next year's Meteoriks awards "best writeup". If the category is added as Caulky hopes.
It is an entertaining and detailed description from the start of the demo group to the end of the demo.

Swedish Atari Klubben's traditional "Slaskhack" is taking place from 20th o 22nd of March 2026 in Falköping. Currently, about 20 visitors are expected.
As the official announcement indicates, there is room for a cozy culture clash between:
"1. Traditionalists! Unite in the separatist group V.I.N.T.A.G.E. (Vampire Is Not The Atari Genuine Experience). The slogan is "Boo for Gigabyte"! (club chairman).
2. Forward-thinkers! The club chariman probably cried a little when color TV was introduced and called SVT in anger when we got more TV channels."
Sounds like a place to be!
And reminds me of this! ;)

The overly talented AY-musician Pator traditionally active on the ZX spectrum scene published an alpha version of a new AY/YM tracker working in the webrowser. Bitphase has a slick interface and comes with full pattern and instrument editor. This looks like a modern and flexible solution for creating AY/YM tracks.
The slick Bitphase frontend
You will find a few demo tracks in the tracker, e.g. Pator's great Kizuna track he did for the related smfx/Joker demo.
Also, there are good news in Atari matters. Timer effect support is on the plan, and of course those timer based sounds are going to be made exportable as well. While the track so far had .psg export, just today spkr/smfx put a cherry on the cake and implemented .sndh support. So by this day we have a new Atari tracker I would say!
SNDH-export - the most important feature, obviously!
All this raised our interest, so with the help of spkr/smfx we were able to conduct a quick interview with the creator himself!

TheNameOfTheGame, a long time user at the Atari-Forum recently released his take on Phase scrolling on the Atari STe.
The examples cover both infinite horizontal and vertical scrolling using a tile map. The assembler source is is available and the examples can be built with VASM, but likely easy to get going with Devpac as well.

Whilst we’re waiting for further updates on the Thrust-resembling ‘Cavey Taxi’, Chicane has taken it on himself, to apply some of the techniques and knowledge gained in making the 50 FPS racing game ‘FaSTer’ on the STE, to update the ST version of Lotus 2.
The updates are STE-specific, so you can expect usage of the STE hardware to enhance the original’s gameplay. The STFM version being somewhat stripped down in comparison with the Amiga version according to Chicane. The aim being, as with Lotus 1, to bring this as close to the Amiga as possible.
There is a work in progress on Youtube, it is unclear when this is going to be released, or even if the whole game is going to be updated. A likely outcome could be a single level ‘proof of concept’ release. Chicane thinks that the third part may be a bit too much even for the STE to run decently.
YouTube link below. Yes it is a bit glitchy at this early stage.

Vulture/Odyssey of Synergy Megademo fame (you remember their awesome guest screen "Symbiosis", do you?) published a very interesting article on his and the general Dutch demoscene roots, including some remarkable photo material and current project information.
Odyssey's guest screen stood out of the usual ST demoscreen mass as it featured some beautiful pixel art, advanced design and also some entertaining storytelling elements
Side-note for the more obsessed ones: the blog post also includes an optional "spot the havoc" riddle!

Joska from Norway who brought us "L'Abbaye Des Morts" for the Falcon
some years ago released a new funny and addictive game called:
"DINO RUN"
There are several incarnations of this type of game, which is some
sort of "Flappy-Bird-On-The-Ground" and now we have a Falcon version.
Watch out for the Pterodactyl!

In the second part of this interview we will focus on TAEDIUM VITAE, the latest Dune demo on Falcon that was released at the winter edition of SillyVenture 2025. This time I have also invited Jade (gfx) and Virgill (music) to join Thadoss (code) as they were essential parts in the making of that great demo.
I have to add that Virgill thought that his fellows had done a great job answering this interview and that he did not see what could be added. Too bad but his decision is respected.
STS: First of all, why “Taedium Vitae”? There seems to be different meanings to these ominous words and latin has never been my thing so that some explanations are more than welcome.
