What was the solution? I'm trying to mount all my configs and roms and everything on an external usb so the 'OS' just runs from the card and nothing else.

Would I be able to edit things in folders that are currently denied because of permissions using this method?

I'm still not very happy that I can't edit the NstDatabase.xml file for Nestopia or all of the hoops you have to jump through to change control configurations. Would be nice if this method was a workaround for that.

The docs cover this scenario - take a look at https://github.com/RetroPie/RetroPie-Setup/wiki/Running-ROMs-from-a-USB-drive

@fraser glad you got it working. I would have suggested permissions next but i know nothing about fstab so i would have been useless on that part.

sweetness thanks for the answer

oops ok i've found the issue, it was not so complicated just a probleme of feeding....

I just have my neurons burning since a few days.

Thank you all, I won't bother you again
