W4ME Station – a WASM-4 runtime for Java ME phones

W4ME Station is a WASM-4 runtime that enables unmodified WebAssembly games to run on Java ME phones from the mid-2000s, with 13 bundled cartridges packaged in a compact 275 KB JAR file. The project supports CLDC 1.1/MIDP 2.0 devices without requiring a JIT compiler or network connection, implementing validated WebAssembly execution alongside WASM-4 host APIs for graphics, audio, input, and persistent storage.
