Frequently Asked Questions

What’s the difference between Decrunch and other retro gaming oriented events?

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.

Where did the name come from?

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.

Can my family acommpany me?

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.

Is there a parking spot available?

Yes, there are couple of parking spots available on the party premises. The number of spots is limited, so the sooner you arrive, the more likely is for them to be still available.

Is there any sleeping room or sleeping area available?

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:

No sleeping in places where you might end up blocking emergency exit route
No blocking toilet routes either
No sleeping in places where there are actual people trying to have fun, not jump over someone sleeping on the floor
Be sure to fold your sleeping bag, mattress etc. early Saturday morning (you can unfold it back again at night). Summarising, no sleeping facilities should be set up during day.

No showers are available on party premises.

Can I bring my own hardware?

Obviously! It is important to remember though, that we have limited table spots, so please contact us before the party (the sooner the better) so that we can predict the number of tables we need to rent and make reservations for you.

Why are the tickects that expensive? Can’t it be done for free?

We are not planning to make any income out of the event, however if there is any, it will be given away in the prizes.
