Show HN: 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.
