Few questions (NAS rom hosting and Controller order)?

StuMcBill

I'm still working on getting my RetroPie setup exactly as I would like it. I currently have my ROMs set up to run from a USB Stick, but I would eventually like to have these run on a NAS. I have another Raspberry Pi 3 and was planning on setting that up as the NAS using OpenMediaVault. Is this something I could do retroactively, or would I need to start fresh?

I have 3 controllers set up with my Pi, 1 x SNES 8BitDo (Bluetooth), 1 x NES 8BitDo (Bluetooth) and 1 x Sega Saturn (USB). Is there anyway I can set the SNES one as default when I'm running SNES, NES with NES, Sega with Mega Drive and Saturn etc?

I have also noticed that if I have both bluetooth ones connected, and change games, it sometimes changes the order of player 1 and player 2? Is there anyway I can stop this happening?

Thanks

Yes. Check the link in my signature.

For the first point, and considering your NAS should be up 24/7, the simple way would be IMHO to :

create an NFS share on your NAS : your_nas_ip:/roms
create a mountpoint on the Pi (in /mnt, it's cleaner) : sudo mkdir /mnt/roms
add a line in /etc/fstab for the NFS mount (it will be automatically mounted at startup) :

your_nas_ip:/roms    /mnt/roms     nfs     rw    0 0

mount the roms new folder : sudo mount /mnt/roms
set the owner of the share : sudo chown pi:pi /mnt/roms
copy your roms folder to your NAS : cp -r /home/RetroPie/roms/* /mnt/roms
rename the rom folder on the pi : mv /home/pi/RetroPie/roms /home/pi/RetroPie/roms.bak
create a symlink to standard roms folder location : ln -s /mnt/roms /home/pi/RetroPie/roms

After testing if everything is ok (check loading speed as well, especially for CD-based games), you may delete the old rom folder : rm -rf /home/pi/RetroPie/roms.bak

For the second point, @meleu's joystick selection tool should do the trick.

Perfect, thanks for the replies!

Another quick question, I can mount ext drives on my Mac, so I can edit files on the main retropie partition, with this in mind, is there anyway I can manually replace / edit scraped data?

Some of the games I have scraped have the incorrect pictures or can't find data at all, so I would like to manually create / edit some of them.

Is this possible, and if so, where are the files?
