Flash Memory

Some Neo Geo Pocket cartridges include flash memory as a means of preserving state between sessions. The Neo Geo Pocket application supports persisting this flash memory state into the browser's local storage or optionally to cloud-based storage. The flash memory 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 flash memory to ensure the state is properly persisted.

Feed

This section details how Neo Geo Pocket application instances can be added to feeds.

Type

The type names for the Neo Geo Pocket application are listed below:

  • Neo Geo Pocket: mednafen-ngp
  • Neo Geo Pocket Color: mednafen-ngc

Note

The aliases ngp and ngc also currently map to the Neo Geo Pocket and Neo Geo Pocket Color applications respectively. In the future, these aliases may be mapped to different applications (different emulator implementations) if it is determined that there are more appropriate defaults.

Properties

The table below contains the properties that are specific to the Neo Geo Pocket application. These properties are specified in the props object of a feed item.

Property Type Required Details
rom URL Yes URL to a Neo Geo Pocket (or Color) ROM file or a zip file containing a ROM file.
language Numeric No The language to use for displaying game text (if applicable) (defaults to English).
  • 0 : English
  • 1 : Japanese
    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 Neo Geo Pocket Color application instance (type value of ngc). The rom property value is a URL that points to a Dropbox location that contains the excellent homebrew game Dodger by Ivan Mackintosh.

  "title": "Neo Geo Pocket Color Feed",
  "longTitle": "Neo Geo Pocket Color Example Feed",
  "categories": [
    {
      "title": "Neo Geo Pocket Color Games",
      "items": [
        {
          "title": "Dodger",
          "type": "ngc",
          "props": {
            "rom": "https://www.dropbox.com/s/94dxy7qtahg3mmk/Dodger.ngc?dl=0"
          }
        }
      ]
    }
  ]
}
