ES fresh Ubuntu 14.04 build

[cromwell87]

I have managed to get emulation station to locate and display psx and snes ROMs and even open pcsx and higan. However, when I select the ROM/game in ES it opens pcsx or higan, respectively, but doesn't load the ROM automatically. I've tried all the variations of %ROM%, "%ROM_RAW%", %BASENAME% with no luck. If anyone has a working es_system file I would love to see it.

ps. whats retroarch and do i need it?

Detail:

``` snes Super Nintendo Entertainment System ~/.emulationstation/ROM/SNES .smc .Smc higan %ROM% ``` snes snes ``` ``` PSX Play Station ~/.emulationstation/ROM/PSX .bin .Bin pcsx "%ROM_RAW%" ``` psx psx ```
