DJBarry, not every SMS/GG game was released for the Virtual Console though, so the OP does have a valid reason for using SMS Plus over Virtual Consoles.
Having said that, SMS Plus is a homebrew port of that emulator. Dunno much about getting homebrew to work in Dolphin, but I'm guessing the easiest way would be to dump your NAND on a real Wii with SMS Plus already installed on it.
Failing that, if all you really want to do is play Light Phaser games on your PC, just find a desktop emulator that emulates that functionality via the mouse, then use a program that translates Wiimote input into mouse movement and mouse clicks.
