This competition is about making software that can run on actual game boy hardware.

- The entry must implement/interpret the jam theme (applies to Game category only).
- The final deliverable must consist of a GB or GBC ROM file.
- GBC features are allowed (entries may be GBC only)
- SGB features are allowed (but don't rely on them)
- You can use RGBDS (ASM), GBDK (C), ZGB (C), GB Studio, GBSDK(C+RGBDS ASM) or anything that produces a valid ROM.

Your work must be new and original:

Examples of things that are allowed:
- A brand new game using your own (or any) existing game engine
- A remake of your (or someone else's) game for a different platform, but with new code and assets
- A brand new game you barely started (e.g. you only made a title screen or a mockup of the gameplay)
- Pre-made and AI generated assets for art and music are ok if the licensing permits. Make note of what is being used/reused and under what terms. It may be factored in when judging entries.
   
Examples of things that are not allowed:
- A project you've been working on for months
- An update/patch for a game you already released publicly
- ROM Hacks
- NSFW content

Categories and Prizes

An entry can compete in one and only one of the following leaderboards:
- Games
- Music cartridges
- Demoscene style - This category is for audio-visual demonstrations that run without viewer interaction, in such a way as to demonstrate skill in manipulation of the Game Boy hardware through code, special effects, art, music, and direction.
- Tool - This category is for tools that run on the Game Boy hardware itself
