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 web site 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.

Bad Apple HD released

At Silly Venture 2k18, we have released this Atari 8-bit demo by Lucy, MotionRide and JAC!. Took 5 years to compete and has the following unique selling points

  • works on unexpanded Atari 400 with 16k RAM or higher machine
  • works on both PAL and NTSC machines, PAL recommended
  • only uses passive ROMs and standard tapes, no external CPU, microcontroller etc.
  • 384 x 232 pixels, full overscan display
  • 50 frames per second, dynamically adapted on NTSC
  • real voice audio from the "educational soft" left tape channel
  • additional intro and outro part resulting in 5:35 total runtime
  • 177 MB of raw video compressed to 41 MB of video using unique ANTIC hardware compression
  • 29 MB uncompressed 16-bit PCM audio

 You can read the full story behind it's creation and the technical details  here.

 

Silly Venture 2k17 Invitro revisited

It always very rewarding to see people who like the result of the hard and completely useless demo coding for obsolete machines. So here's nice video from a Polish guy I don't even know.

Click to watch video

"In June 2017 this demo appeared. It is an advertisment for the Silly Venture 2017 party. This demo (or call it invitro) was written by JAC!, Glafouk did music for this demo. It's a 16kb production and it's already loaded here on EPROM. I will keep myself silent 'coz I don't want to make noise. The most important thing is what will happen on the screen in a moment. I hope you will enjoy it. ... .. do, what, how did you like the demo? I am thrilled, call it intro, invitro, Whatever, I am just thrilled. Amazing cooperation of coders, those pals are truly amazing.

Thanks man for these encouraging words! I' consider them a kick in my a... to get my Silly Venture 2018 done and check my hotel bookings asap :-)

Helena's BASIC Games released

Today I can finally release the two Atari BASIC games which I created together with my daughter Helena in 2016. She had to give away her smart phone for two 2 weeks because she did nothing else anymore than playing with the smart phone. Normal family life wasn't possible anymore. Instead she received an Atari 800 XL with two joysticks, a datasette and later a floppy drive. And we sat down together to dive into the essentials of Atari BASIC and game coding.

Pure computing power

Or as an old friend of mine put it "The Atari is exactly what your parents had to take away from you" :-)
In this video she presents the results of our efforts.

Silly Venture 2k17 surprise

Goooooodies
