from Eke-Eke:

This is a port of Charles MacDonald's SMS Plus emulator, based on Softdev's last release, with some compatibility fixes and additional features. Download the latest version and execute smplus.dol on your Gamecube or Wii with your prefered method and then load a rom from ISO9660 DVD or from SDCARD. If you use SDCARD, roms must be placed in the previously created directory /smsplus/roms. Savestates need a /smplus/saves/ directory.

KNOWN ISSUE: expansion controllers (Nunchuk or Classic) are sometime not detected upon initialization. To solve that, simply deconnect and reconnect it from the wiimote.
