I have, for example, Atari2600 roms. For the No Attract Mode I have to copy in the folder retropie-mount/roms/atari2600 and the system recognize the roms.
For the Attract mode I have to copy in piroms/atari2600 and the system recognize the roms.
Ok so I am guessing here that no Attract Mode means EmulationStation. Am I correct? If so please just say Emulationstation
Second let me made sure I understand:
1. You want all the games and media on the external HDD with just the operating system. configuration files on the SD card.correct?
Easy to do. (I assumed that you already have done it.) If everything is on your HDD..
I do not know why you have two folders of roms for the same system. That is not needed. If the path retropie-mount/roms/atari2600 works with emulationstation then all you have to do is set up Attract mode to use that path as well.
1. On the main Attract mode screen Press the Esc button
2. Go to emulators
3. Go to Atari2600
4. Got to roms path
5. Enter retropie-mount/roms/atari2600 there
6. Press Escape
7. Now go down to generate list (if is asks to overwrite your list say yes)
8. When done press Esc twice (you should be back on the main screen)
9. look at your atari 2600 list
This can be done with every path (for videos, marquees, etc.) Just point it to the path that is shown. Note that is you are looking at the path over ssh or sfpt (a network) you will NOT get the right folder. You need the local path on the pi.
I find your path strange though normally the path starts with /media/usb0/ for an external device on the pi. That is where you
should be looking for your hdd...from beyond that you can have whatever path you want.
Remember when using a HDD you
MUST have it powered separately the pi can
NOT power the pi by itself it was never designed to do that!

THEN we will work on making work and switch between them.
