Welcome to the WUDSN ursel home page

WUDSN ursel - or short WUDSN - is a demo group founded in 1991. There is an explanation why the group and the site are named like that, but that's a different story you can find in the FAQ. For the time being it should be sufficient for you to know that I, Peter Dell aka JAC! am one of the members ever since. I have created this website to offer my tools and productions and to share the fun I have had for more than 20 years now with my Atari-8 bit computer and other classic computers. To learn more about me and what I'm doing, check out this personal interview that I gave for ANTIC - the Atari 8-bit podcast.

Fujiama 2022

The Fujiama 2022 started at midnight in the night from Wednesday the 7th of September to Thursday the 8th of September 2022. It ended sometime after breakfast on Sunday the 11th of September 2022. I don't remember any time in my life when I've used so many different programming languages in such a short time. Thanks, esp. to prodehl, insane, R0ger, and Prodatron for many cool in-depth programming talks. Be clever and save the date for Fujiama 2023 already: Wednesday 30.09.2023 - Sunday 03.09.2023

ASMA - Atari SAP Music Archive - asma.atari.org relaunch

I've joined the ASMA team to update the website which has been dormant and without updates for quite some years. The website has been completely restructured and updated and now offers a powerful search, an up-to-date SAP player in your browser, and exports of SAP files to different formats. More features and improvements are added continuously.

Visit http://asma.atari.org/ and dig into the sounds of the Atari and join the AtariAge thread to receive detailed updates, post your songs for the archive, or report issues.

SillyPack 2k20+1 SE and SillyPack 2021 WE released

Both packs contain a disk image in MyDos format with all Atari 8-bit releases of SillyVenture 2020+1 Summer Edition and SillyVenture 2021 Winter Edition. They contain a results viewer which also acts as a menu from where you can directly start all releases and read the readmes. The menu remains memory resident, so you don't have to load it again every time. This makes watching the graphics entries and listening to the music entries much more fun, esp. on the real machine. These are the controls for the menu:

  • Pressing any key during loading the menu takes you to the DOS shell.
  • Pressing RESET in the menu performs a cold start.
  • Pressing RESET in while a release is running returns to the menu, if possible.
  • Further controls are displayed in the menu itself.

The downloads come with a pre-configured Altirra which you can run with the required settings by simply clicking the "SillyPack2k20_1SE.bat" or "SillyPack2k21WE.bat" file.

Programming the Atari XL/XE - Part 14,15 and 16 released

After a loooong break, the next three parts of the tutorial series on Programming the Atari XL/XE are now available. This time you learn how to use POKEY to create sound effects, how to include Raster Music Tracker (RMT) music into your own code, and how to obtain RMT modules from the Atari Sound Music Archive. A big thanks to Tim Tennyson who motivated me to get back into creating the tutorials. Now that I have a proper setup with Open Broadcast Studio, it's really fun again.
