@gomineko if i Backup is every setup lile scrapper or controller configuration the same ?
If you backup the SD image, it's a bit-for-bit duplicate of the entire SD card. This copies everything, updates, boot settings, installed packages...the mistyped commands in your bash history...everything. Just like you shut it off and just turned it back on again.
If you copy the roms, bios, and configs over the network share and then restore them to a fresh image, you will still keep most of your customizations (from the "configs" folder) but all your history, updates, etc. will be wiped clean and you will be starting fresh on those fronts.
@rmbell34 I also use the 8BitDo SN30 Pro+. The problem with the Switch mode is, rumble/vibration/haptic feedback doesn’t work (for games that support this feature). This only works in Windows (X-Input) mode. For this mode to function properly, you need to install/update the xpadneo driver. This should fix the long loading times and can be done through the RetroPie-Setup script. However, in Windows mode the star and home buttons are not supported.
@colstar yeah that's understandable if you are new to this. My point is you don't even have to use a UBS stick to transfer ROMs. Can do it all with your PC and its not even a very technical process. But if you like the USB way that's cool
