I was thinking about how to do the updates with FBneo. Same structure as MAME? What do you think?
currentroms -> points always to the "*-full" folder (redirector)
fbneo-x.x.x.x -> thats the update folder for version x.x.x.x
fbneo-x.x.x.x-full -> thats the complete folder for version x.x.x.x
udpate -> there are the new updates for the next offical version
update-packs -> after the update of an offical version the old updatefolder is moved to this subfolder.
