#description     :	This script perform the following
#					Determines if the game being run is a console or an arcade/fba
#					For arcades, it will programatically determine the resolution based on resolution.ini file
#					For consoles, hdmi_timings can be set based on emulator or system
#					Dynamically creates the game_name.zip.cfg file and sets the custom_viewport_height
#					Dynamically add these parameters (video_allow_rotate = "true" and video_rotation = 1) for vertical games
#					vertical.txt contains all the mame 0.184 vertical games
#					Ability to set custom_viewport_width for arcades/fba

#version         :	0.1
#notes           :	For advance users only and would need to be tweaked
