I got my MAME romset on a portable formatted microSD card but can't find the path to set in the emulator.
I'm using a GPD XD+ (2018 upd) which I CleanROM'd .
I read in this forum about the /mnt/external_sd but there's no such folder. There is a /mnt/sdcard though, but it's empty.
Is there a way to see the path to a folder via the system apps? I'm new to Android.
Thanks in advance for any light on this!
