null0 is a small fantasy console. You write a game in whatever language you like, and it runs in a browser and natively on anything - mac, windows, linux, a raspberry pi.A game is a "cart": a zip file with main.wasm in it, plus your assets. Anything that compiles to WebAssembly can be a cart, and 23 languages have real bindings, examples, and a docker image that builds them - from C, Rust and Zig to Lua, Python and Haskell.
The API is small enough to learn in an afternoon: draw things, play sounds, read input, load a Tiled map. Every language gets the same one.
- Quick start - a running game in about two minutes
- Languages - pick yours, and see what a cart looks like in it
- Gallery - all 57 example carts, playable
- The project on github
It is good for learning, for jams, and for the kind of small game that should not need a 3GB engine.
