About Mappy NES Online
Mappy NES Online is a small, independent fan site with one purpose: letting you play the Famicom (NES) version of Namco's Mappy in a web browser, with clear instructions and some background on the game.
How it works
The game runs inside EmulatorJS, an open-source emulator that runs in the browser. Nothing is installed on your device. When you press Play, your browser downloads the emulator and game file and runs them locally in the tab. The emulator is licensed under the GPL-3.0, and its source code is available from the EmulatorJS project.
Settings and any save states you create are stored in your browser's local storage on your device. We don't receive them, and they disappear if you clear your browser's site data.
