The filesize must match 0x004D1280, otherwise the Home Menu code returns an error. The saved Home Menu layouts are stored here.
When saving a layout, the total layout field is increased, then a new layout entry is created with the contents of the current Home Menu [[System_SaveData]] Launcher.dat + a screenshot of the main Home Menu screen is written. When loading a layout, the data from the layout entry is copied into the Home Menu [[System_SaveData]] Launcher.dat.
