demake – one source project compiles to any retro game console ROM
This started life as a graphics tool for a specific problem: gen AI can make retro-styled sprites but can't follow exact hardware constraints of pixels and colors. While building this I liked the idea that I can fan-out to any retro videogame console or handheld's specifications. I then devised my own declarative language - Demotic - to express the game you want to build as concisely and naturally as possible without implementation detail. To work on different machines, you use relative units, like vw, vh, vmin, vmax. It has a web UI, CLI and NPM package. Still a work in progress.

In plain words
Demake is a tool that compiles a single game project written in Demotic, a declarative language, into ROM files for any retro game console or handheld. It solves the problem of ensuring AI-generated sprites conform to specific hardware constraints like pixel dimensions and color limits. The tool uses relative units to adapt games across different machine specifications and is available as a web interface, command-line tool, or NPM package. Currently under active development.

In the wake of all the Unity nonsense, just wanted to toss the Raverie engine into this mix :) We’re building off a previous engine that we worked on for DigiPen Institute of Technology called the Zero Engine with a similar component based design architecture to Unity. Our engine had a unique feature called Spaces: separate worlds/levels that you can instantiate and run at the same time, which became super useful for creating UI overlays using only game objects, running multiple simulations, etc. The lighting and rendering engine is scriptable, and the default deferred rendering…

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
