Battery-backed SRAM

Some Game Gear cartridges include battery-backed SRAM as a means of preserving state between sessions. The Game Gear application supports persisting this SRAM state into the browser's local storage or optionally to cloud-based storage. The SRAM contents will be persisted to storage whenever the pause screen is displayed (or the game is exited). Therefore, the menu should be displayed periodically for games that support battery-backed SRAM to ensure the state is properly persisted.

Feed

This section details how Game Gear application instances can be added to feeds.

Type

The type name for the Game Gear application is genplusgx-gg.

Note

The alias gg also currently maps to this application. In the future, the gg alias may be mapped to another Sega Game Gear 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 Game Gear application. These properties are specified in the props object of a feed item.

Property Type Required Details
rom URL Yes URL to a Game Gear 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 Game Gear application instance (type value of gg). The rom property value is a URL that points to a Dropbox location that contains the excellent homebrew game Wing Warriors by Fran Matsusaka.

  "title": "Game Gear Feed",
  "longTitle": "Sega Game Gear Example Feed",
  "categories": [
    {
      "title": "Game Gear Games",
      "longTitle": "Sega Game Gear Games",
      "items": [
        {
          "title": "Wing Warriors",
          "type": "gg",
          "props": {
            "rom": "https://dl.dropboxusercontent.com/s/uy4teaun7bno0jn/WingWarriors.gg"
          }
        }
      ]
    }
  ]
}

This example can be tested by adding a feed with the following URL within thewebЯcade player:
