-| Home Menu loads the file data here, then writes it to the file again without changing it.
+| Home Menu first tries to use FS:CreateFile with this, which will fail when the file already exists. This file is then opened with openflags=RW. After reading this file, Home Menu then uses [[PTM_Services|PTM:GetTotalStepCount]], then uses FSFile:GetSize. Then Home Menu writes to the already opened gamecoin.dat file.
+At the same time as doing the above, Home Menu also uses(probably from a different thread) [[AMNet:GetTitleIDList3|AM:GetTitleIDList3]] with mediatype=NAND and maxTIDs=0x2000. Then Home Menu uses [[AMNet:ListTitles|AM:ListTitles]] with the NAND promotional-video titleID. Then Home Menu attempts to open the ExeFS:/icon in the NAND promotional-video title.
