A big plus here is, there is a Linux version of PCSX2, so we don't need to use WINE!
Installation
There are 2 ways to install pcsx2 in Ubuntu.
Manually
One just download it from the pcsx2 site, extract it in your home folder, and run the launch_pcsx2_linux.sh(X86 only). here is the pcsx2.desktop file save it in /usr/share/applications/ or in your /home/your username/.local/share/applications/. Edit the file, where it says your username change it to your actual username, and the actual path to the binary.
PPA
If that is to much of a hassle for you, The Gregory Hainaut PPA, is the official PCSX2 PPA, which supports x86 and x64 bit versions of Ubuntu. Due note that the package maintainers have stated:
PPA doesn't allow to upload package on unsupported Ubuntu. In short it
only remains LTS and latest version.
Copy past the following in your gnome-terminal
sudo add-apt-repository ppa:gregory-hainaut/pcsx2.official.ppa
sudo apt-get update
sudo apt-get install pcsx2-unstable
If the PCSX2 doesn't work for you, try the pcsx2-unstable package. One thing you need to do, when configuring PCSX2, is add BIOS files. You will get a window that asks for these BIOS files. You will need to provide legal BIOS“es yourself!
Warning without BIOS'es you can't play the games.
This video shows PCSX2 in action, in VMware, showing off the x86 version. I didn't start the game cause it didn't work well with my screen-recorder.
