Thank you @Nixx this is awesome, now I have a much better understanding how this works, and should be able to figure it out from here

This is incredibly close to my use case, and I am trying to get something like this up and running. I have a server that all the ROMs are stored on, with a copy of LaunchBox installed on it. This is my master copy that is set up to be completely portable. I also store all the media on the server, so none of it is in the LaunchBox installation, keeping its size to a minimum. I then copy the LaunchBox folder to another machine, mount the drive containing the ROMS and the media, and when you try to launch a game I have a batch file that checks if there is a local copy of the ROM. It copies it to the local machine if there is not, then launches it from there. Essentially, it "installs" the ROM to a local folder before trying to launch the emulator. It works, but it's clunky, and requires the batch file to be the emulator associated with the ROM instead of the emulator itself, causing other issues. I also have to create a new batch file for each emulator as launch commands are different for each one. What I would like is for there to be a "middle-man" plugin that handles the copying automatically, with a progress window, then changing the ROM path for the launch command to the local copy. This would mean any AHK scripting for the emulator would still work, something that is essential for some standalone emulators, storage requirements on the local machine are kept to a minimum, while still giving access to the full library. I tried playing with the DLL you posted but couldn't figure out how to get it to work, LaunchBox didn't give me any indication it was even there as a plugin, so I imagine I'm not doing it right. Can you go over the installation and setup of this for a noob like me? Also, you appear to be my spirit animal, as your BigBoxProfile project is another thing I was going to try to figure out. With my use case above, it would be awesome if each machine LaunchBox is copied to can leverage a profile system so the user can customize how their setup looks and works. When they update the installation from the master copy on the server, it would still maintain those settings. If it also was able to maintain the user's save games on the server separate to other user's saves, my setup would be complete.
