copy roms on Stick and use it from there?!

[MarcoCol]

Hi,
is it possible to copy all roms, which I want to use on an USB-Stick and use it from there, instead of copy all of them to the boot-microSD-Card?

I think I must for this mount the USB-Stick in any autostart-file and change a path of the RetroPi-Project (or of all of those emulators I’ve installed), right?
But how? :)

Yeah it is possible, you just need to change the rom path in ~/.emulationstation/es_systems.cfg

Here is a link to the emulation station setup guide:

RetroPie also tries to auto copy from what I understand so you would need to disable that.

And don’t forget to change the path for save state and save files to another path (on retroarch.cfg). My USB card was read only (maybe yours is not) so i had to put these Save settings back to the original /home/pi/retropie/xxx.
