Yes, the .sh method is working in Retropie 3.0. If you update the Retropie scripts and reconfigure dosbox using the commands in my first post, then you will be able launch games using scripts without having to make any changes to the config files. Alternatively, you could start afresh with the version 3.0 BETA 3 image.
