I installed mupen64plus using this command:
apt-get install mupen64plus, then I tried to run it from the command line, but it didn't found the executable. Then I tried to look it up in xfce's list of program, and it didn't appear in the list. I also followed the instructions from the first answer of this question: How do I install mupen64plus? and not luck either.
The package (https://apps.ubuntu.com/cat/applications/mupen64plus/) is installed, but it says in the software center that it only takes 37kb of disk space (which is ridiculous).
Does somebody knows where is the problem? Thanks.
