Hello good afternoon!
In my case I have 2 devices with LaunchBox, however I wanted to do the following:
-> When I update one, where I put a ROM I can copy "only" the files it needs for this, since my folder has 80GB total, and copying from one place to another all the time is very time consuming.
Example:
In the External HD I put 2 roms of PS1, and when I get home to copy only those 2 roms and the files that I need for the LaunchBox to recognize what I did in the External HD. No need to copy everything again.
Thank you
