OpenSinnoh is a custom engine recreation of Pokémon Platinum that runs directly in web browsers on desktop, tablet, and mobile devices. Developed by Dennis Snijder, it is not an emulator; instead, it parses your own game ROM locally in the browser to rebuild the game using open formats like glTF and PNG.
What you need
Files from your own copy of Pokémon Platinum. The page asks for them before you can play.
Good to know
The port features optional graphical enhancements like cinematic cameras and depth of field, quality-of-life additions like fast-forward and auto-run, and touch controls for mobile devices.
