/* Purpose of this file: Collect boot settings for Core::Init()

   Call sequenc: This file has one of the first function called when a game is booted,
   the boot sequence in the code is:
   
	DolphinWX:	GameListCtrl.cpp	OnActivated
				BootManager.cpp		BootCore
	Core		Core.cpp			Init		Thread creation
									EmuThread	Calls CBoot::BootUp
				Boot.cpp
