DemoSplash 2020

  • Remote Access - Streaming Live on SceneSat and
  • Virtual Event

Demosplash2020  will be online only for our tenth year!  Perfect for sofa-sceners the world around!

Demosplash is one of the largest and longest-running demoparties in North America, catering both to newcomers to the demoscene as well as established artists. We show demos live on original hardware as much as humanly possible, offering a viewing experience that can't be matched by emulators or recordings. In addition to screenings, we feature a variety of events, including tech talks, workshops, and celebrations of retro gaming.

Demosplash 2020 is presented by the Carnegie Mellon University Computer Club.

Featured Events at Demosplash 2020: Event planning for Demosplash 2020 is ongoing, and the site is be updated regularly.

► Talks and Workshops:  Come to hear engaging discussions on topics across the demoscene.

    ► Fast Loading Times on the Apple II: Pushing the Limits of the Disk ][
    Presenter: Vince Weaver
      ⇒ The Apple II Myst demake faced various challenges while attempting to have minimum latency and maximum file sizes on 5 1/4" floppy disks. The demake involved reducing a 500MB CD-ROM game to fit on three 140kB disks, which meant every disk sector counted and space couldn't be wasted. Response time was also key. An Apple II+ system only has 48k of RAM so relatively large disk loads are needed when moving between regions of the game. These loads need to be fast to avoid pulling the player out of the immersive gameplay due to long waits for disk I/O to finish. The standard Apple DOS3.3 disk routines were tried but found wanting; in the end custom disk code designed by Qkumba was used instead.

    ► Digital Archaeology: Uncovering History in Binary Data
    Presenter: Damian Rogers - NPO Game Preservation Society
      ⇒  Fans have been creating "hacks" to modify their favorite games for as long as hex editors and disassemblers have been around. But aside from editing levels or graphics, digging deep into the raw data can help us understand more about the game's development history and staff. Join us as we discuss digital archaeology, the analysis of software code and data to better understand the stories hidden in the mass of ones and zeroes, and have a look at some of our favorite discoveries over the years.

    ► Geometric Approach to Algorithmic Composition
    Presenter: Ashlae Blūm(e)

    ► Retro Gaming
    ⇒ While we aren't able to set up retro gaming platforms for people to interact with over the Internet, we'll be featuring some of our personal favorite retro games at various points during the stream.

      ► Demoscene Fun
      ⇒ Come celebrate the spirit of the Demoscene with live screenings and competitions.

        ► Live Demo Screenings
        ⇒ Throughout the weekend, we'll be offering live showings of demos running on real machines, old and new, from the CMU Computer Club's large collection -- Amiga, Atari, Commodore, PC, you name it! We'll be showing both eternal classics and recent releases. Check the schedule for more details and times!

        ► Demo Authoring Competition
        ⇒ No demo party is complete without the chance to write your own demos and submit them to be screened and voted on by the audience! We have several categories - check the compos page for more info.
