I'm trying a different approach.
With the current ExoDos and Launchbox setup, I have moved the games on another folder.
After that I have replaced the <ApplicationPath>, <ConfigurationPath>, <RootFolder> entries in the xml file with the new path (just for testing "D:Games", if it works I'll move everything to a network drive,, where inside the D:\Games folder there are the games zip files and the !dos folder) while everything else stays the same (emulators, images and so on).
If I open LaunchBox then, right click on a game to open the game folder, then it is redirecting me to the new path, which is good.
However, games do not launch the standard setup, any advice on how this can be solved?
