Emulicious runs on Windows, Linux, Raspberry Pi OS, Mac OS(X) and any other operating system supporting Java SE. All you need to run Emulicious is Java 1.6 or newer. No installation needed – just extract all files and run Emulicious.jar (or Emulicious.exe if you’ve downloaded Emulicious (with Java for Windows)).
If you’re running Windows and don’t have Java installed and don’t want to install it you can download Emulicious (with Java for Windows). It contains the Java binaries necessary to run Emulicious. After the download has finished you need to extract all files to a directory of your choice (running Emulicious directly from the zip archive won’t work). After extracting all files you can start Emulicious by running Emulicious.exe.
In order to play a game you will need a ROM of it. A ROM is an image of a game cartridge. ROMs for commercial games are copyrighted, so it’s only legal to have a ROM if you also own the original game cartridge. You might be able to find some ROMs on the internet. Emulicious also supports zipped ROM files, so you don’t have to extract them before you can play.
