Update For those that don't mind adding PPA's, packages are now available here for 14.04 & 14.10
PPSSPP has a Linux version. The instructions provided only work with the 64 bit version and you have to build the 32bit version yourself, although there is a promise that a .deb for Ubuntu/Debian users is on the way
Download the tar.gz from here
Extract to a place of your choice
You can now launch the application by double clicking the executable.
To create a launcher and make it searchable from the dash:
If you don't already have it installed then open Software Centre, search for and install 'Main Menu'
Open 'Main Menu' from the dash
Select a category where you would like to place your application (for this purpose I have selected 'games')
Click on new item, give your launcher a name i.e PPSSPP then in the command box click browse, navigate to the executable you have for PPSSPP, click open
At this point you can just click OK and your launcher will be created, however there is also the option to to give your launcher an icon (unfortunately no icons are included in the download)
To change the icon click on the 'springboard like logo to the left
you will then be able to select a logo from file or if you have your own navigate to that and select.
If you don't choose a different icon it will just default to the springboard.
I just received the same error, while trying to reproduce the error you experienced.
You need to do sudo apt-get install dolphin-emu-master
by the look of my error. It allowed me to start to install (i.e. it found the package), although I did cancel it.
Was this what you got?
tim@Hairy14:~$ sudo apt-get install dolphin-emu
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package dolphin-emu is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
dolphin-emu-master
E: Package 'dolphin-emu' has no installation candidate
NB: I used this site to get the PPA details, the same PPA as you.

Developer of E-UAE is still. There is another Amiga Emulator: FS-UAE that syncronized with WinUAE code.
