First thing: mupen64plus is not mupen64. We are also not the Ubuntu software
center support team.

Don't know, but maybe you should tell us what you did. Which extra repostories
did you use? What version of ubuntu did you use? Why don't you accept the
installation? Did you remove keyrings from apt? Why didn't you try another
source (hg repositories, source tarballs, prebuild tarballs, ...)? From which
source comes libxdg-basedir1 and mupen64plus? Can you install other official
ubuntu packages (not yet installed)? Did you try to contact someone from
ubuntu and asked him about the problem? Have you tried to install it through
apt-get or aptitude? Have you updated the package index files and are all
other packages on your system up-to-date? ...

Kind regards,
Sven

Sounds to me like he needs to either enable the nonfree repos or maybe set up a particular PPA, not sure which. Most likely the first.
