      Hello,
      I am creating a homemade arcade machine using a Raspberry Pi 3 Model B and RetroPie. I encountered a problem that I haven't been able to fix. When I try to load a rom, I get an error message saying that I am missing required files. I used clrmamepro to verify that all of my roms are usable, so I don't know what the problem is. Any help would be appreciated.

          @dankcushions I'm using a Raspberry Pi 3 Model B, RetroPie Version 3.8 built from an SD image, and I have a usb keyboard and a thumb drive for roms attached. I recieve the error message "ERROR: required files are missing, the game cannot be run" after it lists about 6 files that look to be related to the rom. I used the guide for first time set up on the official RetroPie page, and I am using mame4all as the emulator.

            What method did you use to migrate your roms to the thumb drive?

            RetroPie v4.5 • RPi3 Model B • 5.1V 2.5A PSU • 16GB SanDisk microSD • 512GB External Drive
