Hello, yes, only copy and paste, you can add an image for new Rom added too. I tested it with a 4GB MicroSD and it works fine, it may work with larger ones, but all Romset's on all consoles take up little space. I made a backup of the Firmware using Win32DiskImager and Just burn the image on another MicroSD. Yes, I will test the other possibilities and then I will tell you.
