Changing system settings

There are two ways to achieve this:

Application

Open the Settings (/) panel, and navigate to the Systems section.

Then modify these fields to your liking. Remember to save changes when you’re done.

You can also revert to the default settings by clicking the Restore default system button.

Manually

Edit the rh_systems.json file in the configuration directory. Add a dictionary entry to the existing array, with the name field set to the name of the system you want to modify, and then changing the other key values:

[
        {
                "name": "n64",
                "fullname": "Nintendo 64 (Custom Name)",
                "extension": [
                        ".abc",
                        ".rom"
                ]
                "category": "computer"
        }
]

For more information on the existing keys and their values, see the rh_systems.json specification section.
