STay4Evr SNDH Release
January 16, 2026
It took us a while, but we finally found the code and escaped that brown box.
And we can now present you the release of the SNDH files from our recent demo "STay4Evr".
The package contains all songs from our recent demo "STay4Evr", which we released in July 2024
at the Sommarhack coding convention. It contains two flavors:
- "SID" package: The SID emulated songs, including some additional subsongs which were not used in the demo.
-
"YM" package: The songs in YM mode. Unlike in the demo, where this mode was implemented
by modifying the pulse width, these songs are pure, timerless YM chip musics and they do
sound amazingly well and show the real greatness of the songs and what they could have been
on the YM2149 back in the days.
And it all comes bundled with a small intro to start a Happy 2026.
STay4Evr!
July 07, 2024
A stupid idea worked out well and quickly got out of hand, crazy enough to make it into a demo.
We are happy to present STay4Evr! This is our biggest release since ...do things. in 1999!
5 demo screens, 109 tracks, 6 hours, 58 minutes of music and a very unusual interactive main menu
beaming you directly into the year 1985/1986. You won't believe your eyes and especially not your
ears. Think twice before you enter. Once you are inside, you are trapped in a small ugly brown box
with no way out ...
Face it ... You have to STay4Evr!
YM2149 based SID Emulation
STay4Evr honours the early days and the roots of chipmusic showing an emulation of the C64 SID
on a YM2149 soundchip using nothing but modern timer techniques! No lazy DMA based waveform calculations
are performed. This is real chipmusic revealing classic tones not expected to be
heard from the YM2149 soundchip. Presented in three demoscreens with a powerful playlist mode it
can run all day.
Fully functional C64 Basic
The main menu is a fully functional C64 Basic with the ability to load the individual demo
screens. It is not just emulated, in fact it is running in 68k, which means the original
roms have been reassembled and transpiled to 68k code. Due to using plain 68k code
and leaving off a 6502 emulation it is running faster than a C64.
The G.O.A.T. Demo
This demoscreen is showing the YM2149 playing the old Rob Hubbard songs
using the new techniques. Visually inspired by a classic space game, the selection of the
songs inevitably reminds of the "B.I.G. Demo". To remember that demo and to honour the author of
these great songs it had to be the "G.O.A.T Demo".
Under the Waves
This beautiful one honours another outstanding composer from the early C64 soundchip era. One might recognise a
visual reference here and there, but at least the sounds reveal the author. Martin Galway, with his very unique
style leaves his remarkable footprint in the history of chipmusic.
Guardians of Mana
The third demoscreen collects various songs from the early era and
brings us the magic of classic chipmusic embedded
in its very own visual appearance remembering the
classic C64 intro. And when we listen to the opening
song, we will remember the gifted Ben Daglish and his
outstanding talent, may he rest in peace.
And there is more. Just explore the package.
ultraBooST!
August 12, 2022
Get ready for "ultraBooST", our first demo since STresSTeST in 2015!
This one is a little different, as it is not a plain Atari demo, but a demonstration
of what would have been possible if the Atari had nicer screen modes and custom chips.
It is a showcase of an fpga based extension board developed and built by ultra. It provides
additional screen modes and helpers and hence emulates some kind of custom chip like other
systems have them by default. Except from displaying the screen data for additional screen modes
everything else is just plain and optimised M68000 assembly code without the hustle of
concepts like c2p consuming much of the available Atari CPU time. Even the music is
classic timer based YM2149 sound. Ranked 1st place at SillyVenture 2k22SE.
Just check out the information files in the package to read more, even about the special
version of STeem which provides an emulation of the additional screen modes.
STresSTeST released!
Dec 20, 2015
Please welcome STresSTeST, our first demo in about 15 years!
A real surprise, even for ourselves. When we came together after years, it felt really good and
we felt the spirit and the energy to do things again. This demo was put together in very short
time to present something at STNICCC 2015. It was very close but we finally did it.
Please check out the demo section and download STresSTeST!
