DECRUNCH 2023

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.

Data

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.

Other rules

Organizers reserve the rights to merge compos with insufficient number of entries or split them if there are more than one entry for certain platform. For example if there are at least three demos for Atari, C64, ZX Spectrum or Amstrad and it doesn't cannibalize already announced competition we will organize dedicated demo compo for given platform.

Laptops are allowed only for cross-development purposes.

Remote entries should be:

• sent via email to party@decrunch.org or
• uploaded into party system (link will be published later).

Deadline for remote entries is 23rd June 2023 23:59.

One entry per single person in msx and gfx competitions. Same person is allowed to be featured as collaborator in other production in the compo.

We have following hardware available to improve entries' delivery and testing process:

• 1541U2
• GOTEK Cortex and HxC
