IIRC, you have to do it either by USB, or by adding them directly to the folders on the SD card. Here’s the retropie guide:

What went wrong? Did you have you USB drive formatted as FAT32?

That process definitely works (I’ve done it before myself).

Hi Beau,

Just to confirm, you’re using an OTG adapter to plug a USB flash drive (not hard drive or SSD), plugged into the USB port on the back of the GPi?

If you’re using a hub, you should be able to hit F4 on a keyboard to escape to the shell, where you can type `lsusb` in order to see if your drive showed up. I’m not familiar with RetroPie’s mounting system, but this should be independant of mounting.

Let us know when you’ve done this and we’ll look into this further
