Could you please give more info about specific differences of keeping OS on USB? –
1) Should I change relative paths in config files of retroarch and emulators?
2) Does it possible to make full USB image backup of tuned up system using Win32Diskimager? It has now 2 partitions. Acronis maybe can help?
3) Do we need any special attention to inserted SD card (it is used as “boot forwarder to USB”, am I right?
4) any other points related with keeping OS on USB?
Thanks for your notes and replies!
