The procedures described above, as well as additional step-by-step tutorials and tips are illustrated in video on our YouTube channel:


Using a database:
What is a database and why use one?

By default, mGalaxy lists files by the way they are named, but this information alone is often not enough:

  • the filename itself may be abbreviated or incomplete and therefore not represent the real name of the game.
  • you would like to have additional information, such as a synopsis, the genre of the game, the number of players allowed, the release date.


All this information can be collected automatically by mGalaxy_Runway when creating a database.
Note also that in this process, image and video files can also be collected!

Using a script:
What is a script...and why use it?

When using an emulator with mGalaxy, 2 criteria are induced:

  • the emulator must be able to run in full screen.
  • you must be able to exit the emulator by pressing the ‘ESC’ key.


Sometimes an emulator will not allow to specify one or all of these 2 settings in the application. In this case, you need a ‘script’.

A script is a small piece of software between mGalaxy and the emulator to execute tasks that are not natively provided by the emulator.

mGalaxy comes with all the necessary scripts pre-installed.
