Well i finally got a good recording of the install process for Dolphin on linux. Remember that you have to compile it and you'll need a standard C++ compiler, along with Scons package management.
I stated on the youtube video's description to anticipate issues. It is difficult to stress how many issues there are and how often they happen. It's virtually impossible to play a game in Dual-Core mode for any length of time. And without dual-core mode, games are slow beyond usage anyway. So on my behalf, go to the Dolphin-Emu's website and tell the Devs to add better support for linux. :)
