Combined 32 byte intro compo

From practice we have learned that this category is where things slowly start to get interesting in terms of single effects that can be achieved. Can you create a killer effect in just 32 bytes?

Combined 8 and 16 byte intro showcase

These smallest categories leave no room for error and are about the absolute limit of what can be achieved in terms of moving imagery. This is why we have decided to organise a showcase instead of a competition for these entries. So please submit your unreleased works if you'd like to be included in this awesome showcase with all new content!

Bytebeat music compo

Create music with just simple logical formulas in 256 characters or less (bytebeat, infix/postfix, 8-44khz) using this tool

New to the concept of bytebeats? Check out this page for a quick introduction.

Bytebeat tracker music compo

More into music than bytebeat formulas? No worries, we've got you covered. Create a compatible MOD of 256 notes with a maximum of 15 samples/instruments generated and exported using bytebeat snippets, named like the bytebeat formula (limited to the 22 character instrument name). You can decide to go for 4 patterns with 1 channel, 2 patterns with 2 channels or a single pattern with 4 channels.

We have created this example mod file to help you get started.

256 pixel Graphics compo

We have not forgotten about all those talented graphics/pixel artists out there. But what can you do when you only have 256 pixels and 16 colors from one of our selected palettes (Sweetie 16, Pico-8 , C64, Combi 16) to work with? Pick your dimensions: 16x16, 32x8, 8x32, 18x14, 14x18, 21x12 or 12x21 pixels and surprise us with your best art! You can use any of the above palettes inside the online lospec graphics editor

For those competing in multiple of the size coding competitions, we will have a special multi-category Byte-athlon event. Where we will determine who is the most skilled across all size categories<: 32byte, 64byte, 128byte and 256byte.

* Join the byteathlon by submitting a prod in all categories: 32byte, 64byte, 128byte and 256 byte (oldschool, hi-end or virtual machine).

* You can enter with as many intros as you like. The highest ranked intro per size-category will receive points and will count towards total.

* Points are counted towards a total score depending on competition results (starting at 10 points and decreasing for each author/entry).

* So for between highest ranked entry in the 32,64,128 and 256 byte competitions, a maximum of 40 points can be gained.

* We'll be handing out 2 byte-athlon awards and prize packages.

At the award ceremony the winners of the byteathlon will receive a special byteathlon award as well as additional prizes, this includes an english hardcopy of the book "The Iron Dragonfly", written by fellow sizecoder Sensenstahl.
