RetroArch - WASM-4

WASM-4 is a low-level fantasy game console for building small games with WebAssembly. Game cartridges (ROMs) are small, self-contained .wasm files that can be built with any programming language that compiles to WebAssembly.

• No Glue Code: If you've ever tried to write even a simple "Hello World" with WebAssembly before, you'll know it usually involves writing a bunch of JS and HTML glue. WASM-4 removes all of that, games interface directly with the system through a small API.
• Minimalist: Fantasy consoles force developers to work with limited resources. This makes them simple to learn, and easier to focus on finishing your game.
• Language Agnostic: Use any programming language, as long as it can compile to WebAssembly. Out of the box we currently support: AssemblyScript, C/C++, Rust, Go, D, Nim, Odin, Zig.
