I am new to everything about this so I’m taking it slow and making improvements. I had everything working properly and was going to attempt to hide some emulators that I don’t use (Apple, PCx86, Cave Story, Doom, etc.). I found my “es_systems.cfg” and had read that you can “comment out” emulators by adding a “#” in front of them. Using CyberDuck, I tried to add a “#” just to see what would happen since I had no idea where to type it. I reboot my pi, and nothing shows up. I look back at “es_systems.cfg” and now it’s completely blank. Is there anything I can do? Thanks!
There are three possibilities:
1. open es_system.cfg and uncomment (#) every unnecessary emulator.
2. open es_system.cfg and delete every unnecessary emulator.
3. open /home/pi/RetroPie/roms/*unnecessary emulator* and delete every file. Emulators only show up if at least one file exists.
