Fifth edition of Wroclaw event that combines the spirit of demoscene with retro computing and gaming.
The party is an opportunity for meeting fellow 8 and 16 bit computer fans that were popular in Poland in 80s and 90s (such as Amiga, Commodore, Atari or ZX Spectrum), and demosceners (those from the past, as well, as those still active).

Main theme of the event are heydays (golden ages of our beloved computers). Entries should be dedicated to stock configurations.
By 16-bit we understand external CPU data bus and specialized chipsets' of the platform bit size (i.e. MC68000 equipped Amiga 500 or Atari ST are still 16-bit).
You are free to deliver demo for different stock 8 and 16-bit platform configurations, however you are supposed to let us know in advance and deliver proper hardware, if we are not able to do it.
Floppy disk is a basic data carrier. All non-executable entries should fit into one 3.5" floppy disk, or one side of 5.25" one, depending of popularity of the floppy type on the platform. Executable entries can fit into more then one floppy disk, if rules don't state otherwise.
Organizers reserve the rights to join compo categories together in case of insufficient entry number are delivered for any.
In case there are more than one entry for certain platform it is possible that a dedicated competition will be held.
Laptops are allowed only for cross-development purposes.
Remote entries should be sent to
Deadline for remote entries is 14.06.2019 23:59.
One entry per person in msx and gfx competitions.
Preferred data carriers at the party are floppy disks adequate to the platforms.
We have following hardware available to improve entries' delivery and testing process:
Digitally delivered entries (no data carrier) should be submitted in ZIP archive with filename in the following template
Archive should contain
info.txt file, with the same information.
All entries must be created by delivering people or the group they represent. Entries that have already been presented at other parties or Internet are forbidden and will be disqualified.
Decrunch is a party, which aims to integrate retro computing enthusiasts and promote creativity and entertainment that those, once popular machines still stimulate and deliver. The difference lies in convention of the event, which in two thirds is a regular demoscene party.
It a bit accidental result of brainstorming in a hurry in a search for the name that would represent the idea of the event. Name comes from “Decrunching” – a process of data decompression that was previously compressed with what we called “crunchers” back in the days. The process allowed for example to fit more data into a floppy disk, but obviously not only that. Usually, during decrunching process there were some color flickering effects or background color switching effects displayed on the screen.
