WASM-4 is a low-level fantasy game console for building small retro games with WebAssembly. Games are self-contained .wasm cartridges built with any language that compiles to WebAssembly, runnable in browsers and on native runtimes including microcontrollers.

Use cases

• build a retro 2d game with wasm
• make a fantasy console game like pico-8
• learn rust or assemblyscript by writing small games
• create tiny wasm game cartridges under 64kb
• add rollback netplay multiplayer to a retro game
• run a game on a microcontroller with webassembly
• experiment with new programming languages through game dev

When to choose

• you want a minimalist, constrained environment to finish small games
• you want to write games in any wasm-compatible language without JS glue code
• you need portable games that run in browsers and on low-powered hardware
• you want instant online multiplayer with rollback netcode for free

When to avoid

• you need 3D graphics, high resolution, or modern engine features
• you are building a large commercial game that needs a full engine like Unity or Godot
• you need more than 64KB of memory or cartridge space
• your target platform cannot execute WebAssembly
