Hey Matris, glad to hear I wasn't the only one running off a NAS But yeah, from everything I tried there was no fix, I couldn't create symlinks manually, and if I wanted to get it to work it would probably take up a lot more space as I would have to duplicate a lot of files between the lanuchbox dir an the core dir in order to get everything to work, its more then themes that require the symlinks, it looks like it creates links for other folders too like manuals, etc...
So for me I just decided to follow Jason's advice and move all my Roms to another folder outside of launch box then use a syncing tool to copy/sync the whole LaunchBox dir to my 3 computers around the house. I wish there were another way as LaunchBox itself is like 250 GB on my disks!!! I hope they come up with a fix soon as I would like to run this on my NAS again eventually as LaunchBox will only grow in size probably, I feel like old Themes should be updated by the creators or deprecated imo to help resolve this issue... but I am probably in the minority there. I know hard decisions had to be made though and I have things working now like I said... just a big pain having all these sync jobs having to run and extra disk space wasted on 3 computers.
