// File description
// -------------
// Purpose of this file: Collect boot settings for Core::Init()

// Call sequence: 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               CBoot::BootUp()
//                                      CBoot::EmulatedBS2_Wii() / GC() or Load_BS2()
