Feed

This section details how SG-1000 application instances can be added to feeds.

Type

The type name for the SG-1000 application is genplusgx-sg.

Note

The alias sg1000 also currently maps to this application. In the future, the sg1000 alias may be mapped to another Sega SG-1000 application (different emulator implementation) if it is determined to be a more appropriate default.

Properties

The table below contains the properties that are specific to the SG-1000 application. These properties are specified in the props object of a feed item.

Property Type Required Details

rom URL Yes URL to a SG-1000 ROM file or a zip file containing a ROM file.
zoomLevel Numeric No A numeric value indicating how much the display image should be zoomed in (0-40).

This property is typically used to hide the black borders that are present on some games.

Example

The following is an example of a complete feed that consists of a single SG-1000 application instance (type value of sg1000). The rom property value is a URL that points to a Dropbox location that contains the excellent homebrew game Cheril Perils Classic by Mojon Twins.
