Also my first post here. I've been eagerly awaiting the new version of Recalbox, and was excited to finally give it a try. The feature I was waiting for was the ps3 controller bluetooth, but I haven't even looked at that yet: all of my roms are on an nfs share on my gentoo box, which is the core of my network. I can gracefully mount them in RetroPie, so this should work in theory, but RecalBox 4.0.2 doesn't seem to boot after making the necessary modifications to fstab as per the git guide.
Obviously, my nfs drives are linux native partitions (ext4). Is RecalBox restricted to fat32 filesystems when mounted in this way, as this thread would imply?
