Hi, I would like to change the default directory of lakka to the Hd of my PC. My Lakka is installed on the USB stick, and I need more storage space for my games. 
Lakka should connect all drives and their content should be available under /storage/roms/<part_name>, so for example if your HD has partition called Games, you should see its content under /storage/roms/Games. If a partition name is missing, I think the partition-id (mumbo-jumbo of letters and numbers and dashes) is used, so it might be something like /storage/roms/1A2B-3C4D or similar (depends on partition type, can be a longer string / name as well for e.g. NTFS / ext partition).
