EmulatorJS

EmulatorJS is a web-based emulator for various system; that is, it allows you to run old games in your web browser. It's based on RetroArch compiled with Emscripten, which is a toolchain for compiling C and C++ code to WebAssembly.

Warning

  • Emulation is a complex and resource-intensive process. As such, it may not work well in all browser, especially older or less powerful ones. If you're having trouble running a game, try using a different browser or device.
  • PSP emulation with the ppsspp core and MS-DOS with the dosbox-pure core are not currently supported when using the Console mode.

Note

Some platforms may require multiple BIOS/firmware files to be loaded at the same time. To do this, create a ZIP archive containing all the firmware files for the emulator you've selected and upload it to the firmware section of the platform. This ZIP file will be recognized by EmulatorJS as the firmware bundle for the platform. Refer to the EmulatorJS documentation for the required list of files for each platform.

Loading saves and states

Our integration with EmulatorJS automates the process of loading and save files and save states. Before starting the game, select a save and/or state file to load (if one is available). Anytime you manually save the game (or create a save state) by clicking the save or "save and quit" buttons, the save and state files stored with RomM will be updated, so there's no need to manually download or upload them.
