The Legend of Zelda: A Link to the Past

About this build

The snesrev/zelda3 reimplementation compiled to WebAssembly. You supply your own US ROM; the page runs the project's own Python extractor in your browser under Pyodide to build zelda3_assets.dat, caches it, and never sends anything anywhere.

Built from

What has been tested

New file created, opening cutscene cleared, Link walked out of his house and across an overworld screen boundary (area 0x2C to 0x2B), 4215 frames, muted. Save survives a page reload and reloads into the game. Nothing past that screen was played; audio untested.

Last tested 2026-10-05 in Chrome 151 headless (SwiftShader). Full playthrough: not verified. How games are tested.

Known limitations

• Audio is off by default and has not been tested; ?audio=1 enables it at your own risk.
• First run downloads a ~13 MB Python runtime to extract the game data from your ROM; later runs skip it.
• Verified in Chrome only. Keyboard only: no gamepad or touch support yet.

Saves

The game's SRAM is stored in this browser via IndexedDB and survives a reload. Clearing site data erases it, along with the cached asset file.
