Some roms load with USB some don't

[michael88]

I am brand new and don't even know what I don't know.

I am running a raspberry pi 3 and just uploaded retro pie. I was attempting the automated upload from USB.

Mame does not show up, dreamcast, or neo geo.

Also when the flash drive is removed everything dissapears.

Any help would be appreciated.
