I tried thos instructions and it just made my Launchbox crash. I think it is because I would have to pullout all of my previous C64dreams from platform.xml and the other and replace it with what is in that doc folder.
Are you using just launchbox as your frontend? I have about 300k games and it is bigger than your drive but some of my games are using a AIO hyperspin rocketlauncher. How can I get my games to be smaller?
