Payload Guest reads payloads 
from /data/payloads/ (From the PS4's internal hard drive) 
and/or 
/mnt/usb*/payloads/ (From a USB devices /payloads/ directory). 


If you have a meta.json file in one of these directories it will parse that file rather than trying to scan that particular directory's files. 
If there is no meta.json file the application will scan the folder and add any .bin files found to the menu, it will look for a .png file with the same name to display. 
Pressing square will refresh the list (For if you inserted/removed a USB device).

Example meta.json
Please note the open and closing square brackets ([ ]).
