The above date stores the last time new Play Coin(s) were obtained. The contents of this file is updated by home-menu. [[PTM:GetTotalStepCount]] is not checked constantly, after home-menu boot this is only checked when waking from sleep-mode. Each time home-menu updates the contents of this file, home-menu will set the Play Coin total to 300 if it's higher than the 300 Play Coin limit.
[[Home Menu]] loads this file / opens this archive during [[Home Menu|startup]]. When accessing this file fails, like when the file/archive is corrupted(or at least on older system-versions), the result is a brick due to Home Menu using [[SVC|svcBreak]]. When opening this extdata archive(0xf000000b) fails, Home Menu executes svcBreak.
