How to use USB external storage for only PS1 roms

[seandecoste]

Hello all, I have found some threads regarding my issue but only for Retropie. Maybe the solution works for Recalbox as well.
I am running Recalbox 9 on a RPI3B.
I run all my roms off my internal SD card (32g). I have a few PS1 games on it as well but want to start running the PS1 games off an external USB key. I know I have to add the BIOS as well to the USB key. Is it possible to use the SD card for all ROMS except PS1 ROMS and use the USB external for PS1 ROMS? Thanks in advance!

@seandecoste You might be able to get it working but it would be a kludge and unsupported: try mounting your usb storage device at /recalbox/share/roms/psx e.g.
mount /dev/sda1 /recalbox/share/roms/psx

But TBH I would just put all your ROMs on the external USB storage (which is a supported config) and be done with it.

Yeah, that’s what I ended up doing. Do I need to keep and of the files that are stored on the SD card? Obviously I deleted the Roms but I what about Bios files? I have them all on USB storage. I mean, they don’t take up a lot of space so I’ll probably just leave them there.
