Draft:TitleBG.pack
TitleBG.pack is a SARC archive which is found in Content/Pack. It contains frequently-used files that the game keeps loaded into memory in order to access them quickly.
The archive is loaded by StarterPackMgr (see Executable) and also as soon as the title screen has finished loading by a GameScene function[1] and unloaded immediately after processing is complete[2]. GameScene will always wait for this function to finish before loading any stage that isn't the title stage, such as the main world (MainField) or shrines (CDungeon). Progress is represented by the first 20% of the loading bar[3] on the loading screen. TitleBG.pack is only loaded once per game launch.
