they run fine from a flash or external hard drive. For the shield to work you need to map the controller by installing an old build https://dolphin-emu.org/download/dev/51a...c5a8085ed/
once mapped install a newer build http://dl.dolphin-emu.org/builds/dolphin...0-9122.apk right over the top. As for settings i suggest you read the forums and watch youtube vids. I can confirm this build is working excellent with mario sunshine for gc and newer super mario bros wii with the dolphin bar and official wiimote.
Dont expect perfection
