# You can download the latest version of this script from:
# https://github.com/MiSTer-devel/Scripts_MiSTer

# Version 1.0.3 - 2021-08-23 - New method for checking if the script is run on a real MiSTer system (thanks to MiSTer Addons).
# Version 1.0.2 - 2019-02-03 - Remounting / as RW only when needed; downgraded version from 1.1 to 1.0.2.
# Version 1.0.1 - 2019-02-02 - Remounting / as RW before altering /etc/init.d/ so the script actually works from OSD.
# Version 1.0 - 2019-02-02 - First commit
