To make a build use a local user directory, create a text file named "portable" next to the executable files of the build. With the extension it should be named "portable.txt". Dolphin will check if that file exists in the same directory, then it will not use the global user directory, instead it will create and use the local user directory in the same directory.
I can't go into the mgalaxy program even with administrator setting?
Yes, there is a script and after download I placed into the dolphin folder. With this script I could launch a wii game directly into full screen. Without this script not.
