What it does

A historically important technical precursor: Wasmcraft compiles WebAssembly programs into Minecraft datapacks and has public demonstrations of multiple games, including DOOM, Celeste Classic and an NES emulator running Super Mario Bros.

How it works

WebAssembly compiled to vanilla Minecraft datapacks

Requirements & limitations

Build the compiler from source with Rust >= 1.58; the output datapack runs in vanilla Java Edition with no game modification.

On 2026-10-10 I re-read the public git history of the repository: repo HEAD (2023-05-07, no tags); no change to status, licence or requirements, so the record stands. CurseForge/Modrinth pages and play-testing were not re-checked.
