Ok, here are my thoughts on features for future development.
1. Config File Backup. We should have a menu feature that enables us to backup up the config files simply in order to enable a quick restore but without backing up ROMS and actual software application or OS code as well. Should make for a small backup but one which can be re-laid upon a restored image with the minimum of fuss.
2. On the Emulation Station Rom selection screen a feature to check or uncheck the ROMS for visibility in the list would be great and much simpler than hacking around in the actual file system.
Enjoying RetroPie R3 using Pi3 and IPAC-2. Happ Controls and Trackball in a custom Bartop with a VGA 4:3 monitor. Primarily used for MAME with a little UAE thrown in.
