Well i gave this a try using this guide and got everything on and running. But when in the menu the sixaxis doesn't work properly only the ps button to quit, and i can't get roms to show up either.
Also i can't get back into ydl os after installing. I tried logging in and typing startx but it comes up with an error.
However i managed to loginto ps3 using WinSCP and send roms to it but still no look after a refreshing the rom list.
For just a linux front-end, this looks really good, really sleek, with some custom rom previews in the video it would look great, I like how everything is pre-configured like DS3 driver, graphic tweaks for emus and acceleration. Nice job!
