Join us in a celebration of the smallest with a dedicated sizecoding demoparty/event, held on the weekend of 10-12th February 2023 on Discord and Twitch

We'll be online streaming with intro competitions in different size categories from the smallest to the even smaller. From our 256 byte graphics and nanogame competitions to bytebeat music competition.

Or what about cool size-coded related seminars to get you started, Bytejam, DJ Sets and many other events?

This is the one event where size does matter! Don't miss it!

- Lovebyte 2023: Back by dope demand!


New: 1k Intro Competitions

This is our largest size category and an interesteing point where hand-optimized assembler code and shadercoders will meet. We will consider splitting between oldschool/highend with enough entries.

512 Byte/Bootsector intro competitions

Push the limits in our newest size category of 512 bytes. Oldschool and Hi-End.

256 Byte Intro Competitions

We will have 256 byte intro competitions for Oldschool, Hi-End and Fantasy Console/VM. There will also be dedication competitions for atari and zx spectrum systems if we receive enough entries in the oldschool category.

128 Byte Intro Competitions

Here is where things start to get interesting in terms of size restrictions, the beloved 128 byte intro competition. We will have seperate competitions for Fantasy Console, High-End and Oldschool Platforms. Go all out with an astonishing effect or do something more stylised, the choice is yours!

64 Byte Intro Competitions

We will have a seperate competition for High-End and Oldschool Platforms. If you really like a challenge, try our seasoned 64 byte intro competition. Surprise us with your skills and show us your best effect!

32 Byte Intro Competitions

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. We will have a seperate competition for High-End and Oldschool Platforms. Can you create a killer effect in just 32 bytes?

16 Byte Intro Competitions

This is the smallest sized competition we have at Lovebyte. While it seems like an impossible task, to get anything done in the size category. Our contestants have surprised us in previous years with their contributions, so that is why it will deserve its own compo at Lovebyte 2023.

Nano Game Competitions

Create a playable game in 256 bytes or less. Open to all platforms. We will have a seperate competition for High-End and Oldschool Platforms.

8 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!

Tiny Executable Graphics Competition

Create the best looking executable graphics in 256 bytes or less. Open to all platforms. We will have a seperate competition for High-End and Oldschool Platforms.

Tiny CGA Pixels Graphics Competition

We have not forgotten about all those talented graphics/pixel artists out there. But what can you do when you only have 256 bytes (1024 pixels / 4 colors) from one of the 6 standard CGA palettes to work with?

CGA Palette 0 (high / low)
CGA Palette 1 (high / low)
CGA Palette 2 (high / low)

You are also free to pick your dimensions (for example 42x24, 32x32) as long as it fits in 1024 pixels and surprise us with your best art! You can use any of the above CGA palettes inside the online lospec graphics editor

Bytebeat Music Competition

Create music with just simple logical formulas in 256 characters or less using this tool

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

Out of Compo Releases

Got anything sizecoding related you'd like to share with the world, but none of the competitions above really fit?
Then our Out of Competition category might just be the right place for your production.

After the event, each of the top 3 individual competition winners will receive a digital certificate by Sensenstahl
