+ * 
+ * Entry point: CB2_InitMainMenu
+ * 
+ * Note: States advance sequentially unless otherwise stated.
+ * 
+ * CB2_InitMainMenu / CB2_ReinitMainMenu
+ *  - Both of these states call InitMainMenu, which does all the work.
+ *  - In the Reinit case, the init code will check if the user came from
+ *    the options screen. If they did, then the options menu item is
+ *    pre-selected.
+ * 
+ * Task_MainMenuCheckSaveFile
+ *  - Determines how many menu options to show based on whether
+ *    the save file is Ok, empty, corrupted, etc.
+ *  - If there was an error loading the save file, advance to
+ *    Task_WaitForSaveFileErrorWindow.
+ *  - If there were no errors, advance to Task_MainMenuCheckBattery.
+ *  - Note that the check to enable Mystery Events would normally happen
+ *    here, but this version of Emerald has them disabled.
+ * 
+ * Task_WaitForSaveFileErrorWindow
+ *  - Wait for the text to finish printing and then for the A button
+ *    to be pressed.
+ * 
+ * Task_MainMenuCheckBattery
+ *  - If the battery is OK, advance to Task_DisplayMainMenu.
+ *  - If the battery is dry, advance to Task_WaitForBatteryDryErrorWindow.
+ * 
+ * Task_WaitForBatteryDryErrorWindow
+ *  - Wait for the text to finish printing and then for the A button
+ *    to be pressed.
+ * 
+ * Task_DisplayMainWindow
+ *  - Display the buttons to the user. If the menu is in HAS_MYSTERY_EVENTS
+ *    mode, there are too many buttons for one screen and a scrollbar is added,
+ *    and the scrollbar task is spawned (Task_ScrollIndicatorArrowPairOnMainMenu).
+ * 
+ * Task_HighlightSelectedMainMenuItem
+ *  - Update the UI to match the currently selected item.
+ * 
+ * Task_HandleMainMenuInput
+ *  - If A is pressed, advance to Task_HandleMainMenuAPressed.
+ *  - If B is pressed, return to the title screen via CB2_InitTitleScreen.
+ *  - If Up or Down is pressed, handle scrolling if there is a scroll bar, change
+ *    the selection, then go back to Task_HighlightSelectedMainMenuItem.
+ * 
+ * Task_HandleMainMenuAPressed
+ *  - If the user selected New Game, advance to Task_NewGameBirchSpeech_Init.
+ *  - If the user selected Continue, advance to CB2_ContinueSavedGame.
+ *  - If the user selected the Options menu, advance to CB2_InitOptionMenu.
+ *  - If the user selected Mystery Gift, advance to CB2_MysteryGift. However,
+ *    if the wireless adapter was removed, instead advance to
+ *    Task_DisplayMainMenuInvalidActionError.
+ *  - Code to start a Mystery Event is present here, but is unreachable in this
+ *    version.
+ *    
+ * Task_HandleMainMenuBPressed
+ *  - Clean up the main menu and go back to CB2_InitTitleScreen.
+ * 
+ * Task_DisplayMainMenuInvalidActionError
+ *  - Print one of three different error messages, wait for the text to stop
+ *    printing, and then wait for A or B to be pressed.
+ * - Then advance to Task_HandleMainMenuBPressed.
+ * 
+ * Task_NewGameBirchSpeechInit

+ *  - Both of these tasks destroy themselves when done.
