@windg Thanks, that did it. The old thumbdrive is showing read only even on my windows pc. Think that one is good as gone.

There's a topic in the Raspberry Pi forums for USB SSDs - https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=245931 - pinned at the top of the troubleshooting section.

@mitu So I tried that just now it actually caused a 20 second delay in the start up process. So I reverted the changes and I've actually just disabled the usbmount services manually and added a line in fstab to mount /dev/sda1 as a work around. Now it boots normally every time.

@xtv said in Read psx roms off SD card & USB:

One solution could be splitting this into two subdirectories, like A-J and K-Z, one of them being a symlink to the USB drive.

That would be a simple visual solution to "hide" the separate-location structure. You could also split it on release year or franchise to help hide the fact.

Many thanks for this, I will read through the material and then give it a go. Steve

If you can read them via the terminal, then it's ok.
What happens if you restart Emulationstation, after booting ? Will the games show up ?

@2fst4u To be fair, this is the most common problem when dealing with a Pi Zero - the hub. Glad you got it working.

@ZioDarkmage
sudo fsck.fat /dev/sda1
I always have this where it says it was not properly umounted. I'm looking into it.
Oh well, It is probably nothing.

@chubsta said in Clarification on running roms from usb drive please:

Transfer the existing RetroPie file structure

That's clearly under the Manual Mount section and - obviously - in direct contradiction with the previous sentence from the Automatic method

It will proceed to automatically copy the RetroPie folder AND all of its contents (you may need to reboot to start the copying)

ok sry

@steptoe Have a look at this link. exFAT is faster than FAT32.

@jonnykesh I meant @rbaker. The TO got it right IMO, talking about transferring ROMs to the USB drive and linking to the right docs for that.

@djpj3000

Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

https://retropie.org.uk/docs/Running-ROMs-from-a-USB-drive/

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.

@mitu I never ended up doing this I realized I'm an idiot and I could just transfer all the other ROMs to the SD card lol thanks for the help though

@chipsnblip said in Savestates save slowly:

avestate_directory = "/home/pi/RetroPie/SaveS

I thought of this solution but I also use the hard drive on PC with Retroarch. It's helpful to have the savestates in the same folder as the rom! ;)

@Allanbuzzy You can't speak of a installation here! The usb helper script only copies the roms from the sd card to the usb stick and keeps them on both! It won't delete anything

If you plug in the usb and start up retropie it mounts the usb device to the /home/pi/RetroPie folder, so everything on the sd card is "hided"!

@spud11 after loging in through ssh, you can use "du -sh <directory>" to check the size of the directory and can also use "ls <directory>" to see all the files that are in <directory>

[Not sure this is what you're looking for but....]

This is what I've done (ignore the attract mode bit) -

Runs it all from the HDD (SD card is still needed), has been working fine for me.
