[older update history at the bottom]


To install Snes9x GX you will need to copy over the "apps" and "snes9xgx" folders (directories) from this archive to your SD Card. It comes pre-packaged in the Homebrew Channel format (which you will use to launch the emulator). Once you've copied the directories to your SD Card you will need to place your ROM image(s) into "\snes9xgx\roms" directory and place any cheat code files (optional) in the "\snes9xgx\cheats" directory. Once this is done you can proceed to run the emulator via the Homebrew Channel.

Satellaview (BS-X)

Snes9x GX supports loading BS games. The BSX BIOS is not required. If you wish to use one, download the English + No DRM BS-X ROM here:

Put it in your snes9xgx folder, renamed to BS-X.bin.


The first time you run Snes9x GX it will create a new "settings.xml" file on the SD Card which stores the configuration of the emulator. So when you run Snes9x GX it will automatically detect your storage medium and will bring you to the ROM selection screen. If you want to run a game with the default settings then just highlight the game and press "A" on it and it will load. However, you can configure Snes9x GX to your liking.


To configure Snes9x GX press "A" on the "Settings" box. This will brings up the "Settings" screen where you can configure the Button Mappings, Video, Saving, Menu and Network. You can also restore the settings to their initial values by clicking on the "Reset Settings" and you can return to the ROM selection screen by clicking on "Go Back".

Button Mappings

Once in the Button Mappings settings menu you'll have the option to pick to configure the SNES Controller, Super Scope, SNES Mouse and the Justifier. Once you select a controller to configure you will be presented with which input device you would like to configure. To set the button simply click on the input device you wish to use and then pick the button you wish to map. After you select a button to configure Snes9x GX will prompt you to press the button you wish to assign to the button you've selected. Below is a list of each controller followed by the input devices and the default values for those devices.

The Video settings screen will allow you to configure various video settings including the Rendering method, Scaling, Filtering, Screen Zoom and Screen Position. You can toggle the options for the first three selections by clicking on them. To make the Filtering option you select you must enable Filtering under the Rendering setting.


  • Unfiltered
  • Original
  • Filtered


  • Default
  • 16:9 Correction


  • None
  • hq2x
  • hq2x Soft
  • hq2x Bold

Screen Zoom will bring up a menu where you can adjust the Zoom level by using the left and right arrows that you can click on. The default setting is 100%.

The Screen Position option will bring up a screen with four arrows that allows you to move the position of the output. You'll only need to use this option if the screen is not centered. Combining this with the Zoom and Scaling you should be able to get a proper display on your television.


From this setup option you can configure the way Snes9x GX loads and saves. Your options are Load Method, Load Folder, Save Method, Save Folder, Auto Load and Auto Save. Clicking on all of the options except the folders will let you toggle through their settings. Clicking on the folder options will bring up a text box where you can enter in the folder you wish to use for your save data. Snes9x GX has two types of saves - one is the SRAM which is the save game data (this is only applicable if the game you're playing supports saving) and the other is Snapshots which are real time saves. Real time saves allow you to save your game in it's current state and resume it at a later time.

  • Load Method - SD, USB, DVD, Network and Auto

  • Save Method - SD, USB, Network and Auto

  • Auto Load - SRAM, Snapshot and Off

  • Auto Save - SRAM, Snapshot and Off


This settings screen will allow you to customize a few aspects on how the Menu works including the Exit Action, Wiimote Orientation, Music Volume and the Sound Effects Volume. The Exit Action can be set to "Return to Loader", "Return to Wii Menu" and "Power off Wii". The Wiimote Orientation can be set to Vertical or Horizontal and then you can increase and decrease the Music and Sound Effects Volume.


Artwork, covers or screenshots will be displayed on the main menu when each game is selected. Select which type to display on the menu by going to Settings > Menu > Preview Image. Each image resides in the respectively named folder (eg: sd:/snes9xgx/covers). They should be a PNG named exactly the same as as the rom and sized no more than 640px by 480px. Recommendend format is 316px x 224px PNG with a 32bit depth.


If you're going to be using your Network (LAN) to load and/or save from you will need to enter in the SMB share settings you've setup on your computer via this settings menu. You will need to enter in the SMB Share IP, Share Name, Share Username and Share Password. If you do not have a password on your SMB share then set the SMB Share Password to "0".


The File Browser will automatically load when you start the emulator and it will automatically list the contents of the "\snes9xgx\roms" directory on your SD card. Like mentioned above in the Configuration -> Saving & Loading you can specifically a different directory to load from. To launch a game (the game can either be uncompressed or inside a ZIP archive) simply click on it and it will load. You may also change the directory you're in by clicking on "Up One Level".


Once you load a game you can access another option menu by pressing the "Home" button. This will bring up the Save, Load, Reset, Controller and Cheats options. From this menu you can also return to the File Browser by selecting "Main Menu". To leave the menu and resume game play select "Close".

The Save option will allow you to save either your SRAM or a Snapshot. Once you've selected Save two options will appear named "New SRAM" and "New Snapshot". Clicking on these will create a new save. Once you have a save you can save over it by selecting it instead of a "New" option. The Load option will allow you to load your saved SRAM or Snapshot. Reset will reset the game. If you pick Controller you can toggle between which controller you wish to use to control your game with. The last option, Cheats, will allow you to toggle your cheat codes (see below).


Cheats are loaded from the "\snes9xgx\cheats" directory and must be in the SNES9X .CHT file format. They also must be named the same name as the game you're playing with the .cht extentsion. An example would be if you have a ROM called "Super Mario World.smc" you would need to name your .cht file to "Super Mario World.cht". You can find a link to a massive collection of Super NES cheat codes in the Links section (below).


TurboMode increases the playback speed of the game by about 2x. To use TurboMode simply press the c-stick (yellow control stick) to the right and hold it right as long as you want playback to be double-speed. Release the c-stick when you want normal playback speed to resume.


Snes9x GX now includes the ability to load SRAM from Snes9x on other platforms (Mac/PC/Linux/etc) and to save back to those platforms.

To load a SRAM file on the Wii or Gamecube from another platform, ensure the name of the SRM file matches the filename of the ROM (except with an SRM extension).

To use a Wii/GameCube SRAM file on another platform just do the opposite: copy the saved SRAM file to the other platform. You may have to rename the file to be what that version of snes9x expects it to be.



  • Added: SD slot B options for freezes, sram and loading of roms
  • Changed: SMB options no longer displayed in menus when run on a Wii
  • Changed: Game auto resumes running after resetting when choosing the "Reset Game" menu option
  • Fixed (maybe): Reading of DVDs past the 1.36 GB barrier (Wii only) please test! - svpe


  • Fixed: Zip compressed freezes to memory card could become corrupted as the file size changed - fixed this by deleting the existing file before writing a new one if the file size increased. If the file got smaller or stayed the same the original file is updated, using less of the existing file if the actual file size is smaller. A check is made before deleting the existing freeze file to ensure that there is enough space available for the new file. Note that additional space equivalent to the new file size must be available. If not enough space is available the original freeze is retained and the user is informed of the lack of space.
  • Fixed: If option to auto-load freeze was selected, joypad config would not be restored since that is stored in SRAM. Resolved this for now by first loading SRAM if any and then loading the freeze. Obviously having to have both SRAM and freeze is not ideal, but this gets the job done if you have enough space on your memory card, SD card, etc.
  • Added prompt when returning to the menu with autosave enabled allowing the user choose whether or not to perform the save. Press A to save or B if you don't wish to save.
  • Added optional verification of Gamecube memory card saves. After writing the file it reads it back in and verifies that the written file matches what was to be saved. If it doesn't or if there was a problem opening the file it reports the problem to the user. Set this option in the preferences if desired.
  • Added Reset Gamecube/Wii menu item
  • Experimental DVD support for reading beyond 1.36 GB barrier on Wii. I have no way to test this, so please report on whether or not it works! Based on svpe's code.

NOTE: due to changes in the settings, this version will reset your emulator options settings, so if you had saved preferences you will need to make your changes to the emulator settings again and save them.


  • Fixed: Going up a directory when selecting a rom on a DVD wasn't working


  • PAL Wii support - no separate version necessary! - eke-eke
  • PAL roms now play at correct speed via internal timer, ntsc roms still use more accurate VSYNC timing - eke-eke
  • Zipped freezes to memory card - take 9-12 blocks or so - based on denman's code
  • Added option for auto save and load of freezes. For saving, can do both SRAM and Freeze if desired
  • Memory card saving and loading shows a progress bar
  • More miscellaneous ease-of-use improvements and cleanup
  • Fixed: pressing B to get out of a rom file selection screen no longer drops you all the way back to the main menu. Now goes back to choice of where to load ROM (the "Load from DVD", "Load from SMB"... screen)
  • Fixed: loading of joypad configuration in SRAM works again - no longer gets messed up


  • B button implemented in all menus (returns to previous menu)
  • Fixed bug when freezing state to SD card - would crash if SD support was not previously initialized
  • Fixed double A button press needed after manual prefs/sram save to memory card
  • Fixed delay after pressing A button after saving freeze to SD card
  • Fixed problem of ".srm" SRAM file being created when SRAM was saved with no ROM loaded
  • Fixed version number in SRAM and preferences
  • Minor other code revisions
