This works perfect, have it installed on a 16GB usb thumb drive and even have roms installed on it and it works perfect for plug and play. the only thing is the Playstation, psp emulators dont work to well yet for this version but every thing else works perfect, herb_fargus is the best, make sure to check his other videos on youtube also. helped me out a lot when i was getting started with Retropie on the Raspberry Pi
