I am attempting to do something like this as well... It is not going very well. I realized I didn't have enough space on my HD for all the games. Someone gave me an SSD drive that they were not using, and I purchased another one to get a little more room for some games that I thought may require more speed, so I have (2) SSD and (1) HDD. That is where I went wrong. I ended up copying all of my games to an external HDD, then copied my hard drive to an SSD using Acronis. I then put all games back on the HDD, and tried to move things around in LB so they were all pointing to the correct path. I got frustrated and moved all sorts of things around that I shouldn't have. I decided to uninstall LB and start over again. All my paths are correct, MAME works inside MAME but none of the games work in LB. You click on them and nothing happens.
