Sixth edition of Wroclaw event that combines the spirit of demoscene with retro computing and gaming.
The party is an opportunity for meeting fellow fans of 8 and 16-bit computers 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).
This year’s edition consists of three parts:

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.
Yes, of course. However it is important to not leave kids without proper attention. Just be a responsible parent.
Please remember, that Saturday and Friday evening events are 18+ only, and no children are allowed on the premises.

No, the party place is not fitted with any dedicated room or space for sleeping, however if noise and party activities do not bother you, you can unfold your sleeping bag in the party hall. If you’re planning to do that, beware of the following rules though:
