This application can NOT be opened in the Finder by double-clicking, because no graphical user interface was ported to the mupen 2.0 API yet. To use, launch the terminal, then cd into mupen64plus.app/Contents/MacOS/ and use a command like "./run.sh example.v64"

Please note that this is an alpha build, which is NOT meant to be used for playing games.
If you cannot follow the instructions above then this is not meant for you =)
