Setup & Installation

Unzip the archive's contents directly to the root of your SD or USB device.

Via Homebrew Channel

The most popular method of running homebrew on the Wii is through the Homebrew Channel. If you already have the channel installed, just copy over the apps folder included in the archive into the root of your SD card.

Remember to also create the snes9xgx directory structure required. See above.

Wii Channel

wilsoff and MrNick666 were gracious enough to create an official Wii Channel. You can find it on the Downloads page.

Loading Games

By default, roms are loaded from "snes9xgx/roms/".

Your SNES rom images must be in SMC, SFC, SWC, or FIG format. Generally, all images you find will be in this format, but if you run across one that isn't please download RTOOL which will allow you to convert the image into SMC format.

From DVD

  • ROMs can be burned to a DVD-/+R (4.7GB max size & ISO 9660 file format).

From Network (via SMB)

Using the emulator via network requires that your Wii is configured for your wireless network, and that you've set up a file share. You must provide a username, password, share name, and IP address to log in to the file server (in settings.xml). This XML file is created for you upon first loading the emulator and entering/exiting Preferences. Here's an example snippet for your XML configuration file:

<section name="Network" description="Network Settings">
   <setting name="smbip" value="" description="Share Computer IP" />
   <setting name="smbshare" value="wiifiles" description="Share Name" />
   <setting name="smbuser" value="yourusername" description="Share Username" />
   <setting name="smbpwd" value="yourpassword" description="Share Password" />

Also be sure to mirror the required directory structure within your share folder, or change the LoadFolder and SaveFolder values in the XML file. See the tinysmb page for additional information and troubleshooting.


By default, cheats are loaded from "/snes9xgx/cheats/". Cheat files must be placed in the cheats folder and named identically to the ROM name, except with a CHT extension. After putting the cheat file in the proper place and naming it correctly, you can access cheats in-game by pressing 'Home' after loading a game. A Cheats menu option should be available.

Language Patches (IPS/UPS)

IPS files must be placed in the same folder as the ROM you are loading, and named identically to the ROM name, except with a IPS extension. They will be loaded automatically upon loading the game.
