# Mega-Attract-Mode configuration file

# Mega-Attract-Mode is split into modules. Each module can be a
# short slideshow or a self-running demo (like a game's built-in
# 'attract mode'). Modules are run in the order listed here, one
# after the next, until interrupted by user input. The last-run
# module is tracked in the global prefs file.
#
# Format:
# key=value
#
# |key| must be unique within this file
#
# |value| must be one of
#   0 for self-running demo (|key| is an executable binary file in /demo/)
#   1 for title slideshow (|key| is a file containing a list of HGR graphics in /hgr/)
#   2 for action slideshow (|key| is a file containing a list of HGR graphics in /action/)
#   3 for DHGR title slideshow (|key| is a file containing a list of DHGR graphics in /dhgr/)
#
# Blank lines and lines beginning with '#' are ignored (like this one!)
