Cinderella: KUVO's Sight 4 draw

[ Atariscne.org - News ] Cinderella: KUVO's Sight 4 draw

Here comes a little weekend starter kit. A production by a scener you may not haven't heard of, a release that is possibly widely overseen, for a platform many may not have heard of yet:

Kuvo of Caroline Software Incorporated released a new music disc for the Russian Elektronika BK-0010 computer (seeΒ wikipedia entry). And indeed, there is a scene for this one. And for a brief moment, the tiny Atariscene feels overdog! ;-)

Anyway, this music disk is quite a surprise, once you found it. It comes with one and a half hours of music for the twin brother of the YM2149F chip, the AY-3-8912. So Atari chipmusic stricken ears feel home immediately.

Very notably, KUVO did all of it, code, music and graphics. If you check is demozoo page you will stumble across an impressive backlog of fantastic ZX Spectrum graphics, too.

Among the tracks there are very enjoyable compositions in various styles, a good flow, sometimes laid back, sometimes uplifting and foremost nicely dynamic and catchy.

But there is more, actually, sound-wise this is way more advanced then the typical AY/YM bleepery. And a reason is found quickly, looking closely at the included VU-meters. The music disks supports 6 channels, so it is tailored for machines with two soundchips. And this offers some quality upgrade for the traditional AY soundscape, nice echoic detuned square leads, interesting slides plus reverb and delay for the masses!

Highly recommended!

Atari ST Dev - Visual Studio Code Extension

[ Atariscne.org - News ] Atari ST Dev - Visual Studio Code Extension

The Atari ST Dev extension for Visual Studio Code is making progress.

Regis Cosnier (Dgis), the author summarizes the extension as follows:

"Atari ST Dev is a Visual Studio Code extension for building, running and debugging C, C++ and 68k assembly projects targeting Atari ST/TT/Falcon systems. It integrates a cross-toolchain using GCC/GDB, provides debug-time views for CPU registers, memory and hardware information, and hooks into Hatari's debugger via the cppdbg debug adapter."

[group order] DSpico flashcart for Nintendo DS

[ scenemarket – latest listings ] [group order] DSpico flashcart for Nintendo DS

[Offer] Peripherals Β· depends on how many people are interested, but roughly €30 (by porocyon) The DSpico is an open-source and open-hardware flashcart for the Nintendo DS: https://www.lnh-team.org/ . For 39C3, I had already organized a group order for a bunch of Nintendo hacking/homebrew people. This was from before these chips were available on AliExpress. The price in that group order was higher (€30/piece) than you'd find on there, but I selected *hard gold* for the contacts, which the AliExpress sellers often forgo. (Which means, mine last longer while the AliExpress ones wear out quickly.) I did not provide stickers, so the carts have an unlabelled black look. (Condition is "mint-condition handsoldered", but I test each cart myself.) If there's any interest, I might organize another group order like this. You can come talk to me at Revision for details about the flashcart, and I can demonstrate how it works in person. --- Interested?

Extremely basic RISC-V VGA demo platform

[ scenemarket – latest listings ] Extremely basic RISC-V VGA demo platform

[Offer] Consoles Β· depends on how many people are interested (by porocyon) I've been working on a 'custom demo platform', with the only constraint that it should be as cheap as possible. This means, you get: * A CH32V003 microcontroller (RISC-V RV32EC, 48 MHz, 16k flash, 2k RAM) * Bit-banged VGA * PWM audio NOTE: **YOU NEED A "WCH WLink-E" TO FLASH CODE TO THE CHIP** It's capable of roughly something like "Craft" by lft (that chip only runs at 20 MHz but it can do I/O operations much more quickly, so it evens out). Unfortunately, other demo projects have taken precedence by now, but I have the parts here. I haven't fabricated any boards yet, but if there's any interest in this, I might make a few and hand them out to whoever is interested. I can bring it to Revision (and show you the code, schematics, etc.) in case you want to know more. --- Interested?

we just launched scene.market: a community marketplace for trading physical items face to face at demoparties.

what is it?
a simple platform where you can post offers and searches for retro hardware, disks, magazines, merch, and other scene-related stuff. no shipping, no payment processing - just arrange a handoff at the next party.

how it works:

  • login with your SceneID
  • post an offer ("i'm bringing my spare Amiga 500 to Revision") or a search ("looking for a C64 PSU, will be at Evoke")
  • pick which demoparties you'll attend
  • someone interested? they claim your item, you get their contact details, sort out the rest yourselves

pricing options: free, buy me a drink 🍺, fixed price, trade, or surprise me

upcoming parties synced from demozoo: Revision, Evoke, Assembly, Deadline, Edison, and 30+ more already listed.

the whole thing runs on Go + HTMX + SQLite, and is operated by Computerkunst e.V. - source will be made open soon.

we'd love your feedback. try it out and let us know what you think!

OpenMPT 1.32.08.00 released

[ OpenMPT - Open ModPlug Tracker ] OpenMPT 1.32.08.00 released

This is a regression update to the most recent OpenMPT 1.32 release to address a single bug.

OpenMPT 1.32.07.00 contained a fix for a crash in the sample mixer, which unfortunately also caused the duration of some sample loops to be altered. This was most notable in MOD files, where chip samples could suddenly be out of tune.

OpenMPT 1.32.08.00 addresses this regression, fixing both the crash and also keeping chip samples in tune.

For a complete list of changes, have a look at the full version history. If you are upgrading from OpenMPT 1.31 or older, read the release notes to get a glimpse of the biggest changes.

Atari Invasion 2026 is over

[ Atariscne.org - News ] Atari Invasion 2026 is over

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.

GCC for asm Experts (and C/C++ Intermediates) - Part 2

[ Atariscne.org - News ] GCC for asm Experts (and C/C++ Intermediates) - Part 2

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.

DawBeat β€” an experimental DAW for bytebeat

A new tool for composing bytebeat has just been published: DawBeat, an experimental browser-based DAW designed to arrange bytebeat formulas on a timeline rather than writing a single monolithic expression.

https://dev.eypacha.com/dawbeat/

The idea behind DawBeat is to approach bytebeat composition more like working in a traditional DAW: formulas can be placed in clips, arranged across tracks, and modulated over time.

Current capabilities include:

  • timeline with tracks and clips
  • drag formulas from a library
  • real-time bytebeat playback in the browser
  • variable tracks and value trackers
  • automation lanes for parameters
  • formula effects and audio effects
  • MIDI input for controlling parameters and writing automation
  • MIDI clock synchronization
  • phone or tablet controller via QR (automation companion)
  • undo / redo and multi-clip editing
  • export compositions to WAV or MP3 

The project explores a different way of working with bytebeat, focusing on composition and arrangement over time rather than a single standalone expression.
