Battery-backed SRAM

Some SNES cartridges include battery-backed SRAM as a means of preserving state between sessions. The SNES application supports persisting this SRAM state into the browser's local storage. The SRAM contents will be persisted to local storage whenever the pause screen is displayed (or the game is existed). 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 SNES application instances can be added to feeds.

Type

The type name for the SNES application is snes9x.

Note

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

Property Type Required Details
pal Boolean No Whether to force PAL video mode for the specified ROM.
rom URL Yes URL to an SNES ROM file or a zip file containing a ROM file.
port2 Numeric No The type of controller that is plugged into port #2 (defaults to Standard).
  • 0 : Standard controller
  • 1 : Multitap adapter (up to 5 controllers)

Example

The following is an example of a complete feed that consists of a single SNES application instance (type value of snes). The rom property value is a URL that points to a Dropbox location that contains the excellent homebrew game Super Boss Gaiden by Chrono Moogle and Dieter von Laser.

  "title": "SNES Feed",
  "longTitle": "Super Nintendo Entertainment System Example Feed",
  "categories": [
    {
      "title": "SNES Games",
      "longTitle": "Super Nintendo Entertainment System Games",
      "items": [
        {
          "title": "Super Boss Gaiden",
          "type": "snes",
          "props": {
            "rom": "https://dl.dropboxusercontent.com/s/uzjekhtrrfyik5h/superbossgaiden.sfc"
          }
        }
      ]
    }
  ]
}

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