I am new to game emulation. I bought a vertical arcade cabinet and have Launchbox with a premium license. I installed Launchbox and it appears to be working as well as Bigbox, but I am not able to play any of the games I have downloaded. I am able to play a few games in Retroarch, so I know that emulator is working and I added Retroach and MAME to Launchbox using the emulator add tool. I am not sure what I am missing in terms of getting the ROMs I have downloaded to show up in Launchbox/Bogbox. Any advice is appreciated.
