# X/Y_Movement_Of_Connection
#~~~~~~~~~~~~~~~~~~~~~~~~~
#
# A X movement is how many map blocks there are to the left of one of your north/south connections.
# A Y movement is how many map blocks there are above your west/east connection.
#===============================================================================
# #4-#5 : Current Map Position
#===============================================================================
#
# This points to the part of the current map (further up in RAM)
# that the connection strips upperleft block is placed on the current map.
