Your cartridge, reborn
Classic 16-bit games, remastered in your browser.
Bring your own ROM. The original game code runs faithfully, with widescreen, modern presentation, save states, rewind and online co-op layered on top.
Your ROM never leaves this browser.
The file is read on your device, identified by its SHA-1 fingerprint, and stored in this browser's local storage (IndexedDB) so you can come straight back. Nothing is uploaded. If you play online, your browser shares only that fingerprint so both players can confirm they have the same game.
