A new version is out for the SNES9X v1.43, a homebrew program that allows you to play SNES games on your Nintendo Wii. This release is from developer Askot, who recently released a NES emulator for the Wii. The program is still in its beta stage so be sure to know what you're doing before you use the application. Here's the changelog for SNES9X v1.43 0.0.9 for the Wii:

Version 0.0.9 - 20080325
* Added SDCARD slot selection for searching roms, meaning, you can search rom files from SDCARD SLOT A or SLOT B (Beta, meaning, buggy, but works).
* For standarization, you must create folders root:snes9xroms to read SNES roms files from SDCARD.
* Added combo L+R+X+Y to call menu.
