With pcsx-rearmed you can press escape and the menu is black with white monowidth font.
The lr-pcsx-rearmed is retroarch and has a colored menu gui.
I would try installing and trying the other of which you haven't tried.
If it is pcsx-rearmed then the controls will still need to be mapped. Navigating the menu to do this I think is possible with the controller but perhaps easier with the keyboard, as well the escape button needs to be pressed. In the controls menu, assign the buttons, if you press left and right on this screen it will show you Keyboard/Joystick/All binds. And don't forget to save the config when you're done.
You could also try installing the alternate driver, for sixaxis/playstation. The sixaxis helper driver is newer and allows other controllers to sync and use bluetooth.
