Because I am using an MBR (not GPT) multiboot USB drive (easy2Boot), I do not want to use Etcher or allow the first boot to create/enlarge the SHARE partition.
So I have extracted the first BATOCERA partition to a FAT32 partition (hd0,1 = first partition) and made a blank ext3 partition (hd0,3 = 3rd partition).
Syslinux and UEFI boot ok (I had to ensure the FAT32 volume label was RECALBOX for v5.26 though).
I can run Batocera, play games and run KODI.
The problem is that although the SHARE volume is present - any changes I make are not echoed at share so I can’t easily add games.
I have even edited the batocera-boot.conf to use the UUID of the ext3 partition
# device to the share data (userdata)
Does anyone have any ideas?
If I use the Developer setting to reformat INTERNAL - will this fix anything or totally destroy one or both partitions?
