Looking for Assistance with ROM Management

i have a raspberry pi 4 8gb model, had no problems with starting roms, they need to be in the correct folder, there is documentation on retropie's website.

For Arcade i tried FinalBurn Neo and it works great

I use this with a Xbox One controller.

But me i didnt have the roms on an sd card but on a usb card. you need to insert the sd+usb first, then it will create the folder-system on the usb.
