Code to pull repos and locally build/transfer development MiSTer cores

MiSTer_Dev_Core_Build.ps1

# Script to pull git repos for MiSTer cores, build locally, and transfer to MiSTer if online and registered in DNS
# Transfer to the MiSTer requires SMB to be enabled and working, with auth working
# i.e. before running the script connect to SMB ("\\mister\") and authenticate, saving the creds.
# Requires git to be installed locally in some form
# Requires a local install of Quartus 17.0 lite with Cyclone V support installed
# More info on Quartus https://fpgasoftware.intel.com/17.0/?edition=lite&platform=windows
