🎮 What is ScummVM Packer?

ScummVM Packer lets you package classic point-and-click adventure games into a single, self-contained HTML file that runs entirely in the browser. No server, no installation — just open the file and play.

⚙️ How It Works

• Your game files are compressed and embedded inside the HTML.
• The ScummVM WASM core, JavaScript engine, and the correct engine plugin are fetched and embedded.
• Common data files (themes, fonts, engine-specific data) are also included.
• When you open the generated file, everything decompresses in-browser and ScummVM boots your game instantly.

🛠️ Technologies

• ScummVM WASM — compiled to WebAssembly from scummvm.kuendig.io
• CompressionStream API — native browser gzip for fast, efficient compression
• Emscripten FS — virtual filesystem to mount game files at runtime

🔒 Privacy

All processing happens locally in your browser. Your game files are never uploaded anywhere. The only network requests fetch the ScummVM engine binaries (WASM, JS, plugins, data files) — and those are cached in memory for subsequent packs.
