0x08680000 4.0.0-7 This loads the u8 mediatype for the current application from already initialized state, this u8 was originally loaded from the same data used by GetProgramLaunchInfo. This then writes the u8 to response-word[2]. This is used with Anti Savegame Restore. None

0x086A0082 4.0.0-7 This is a wrapper for FSPXI command 0x00550082. None

When access rights are required for a command, at least one of the bits in the process accessinfo specified in the above table for the command must be set. Error 0xD9004676 is returned when a process attempts to use a command which it doesn't have access rights for the command. The exheader accessinfo field is all-zero for most applications.

Each session for fs:USER has separate permissions, initially these are set to all-zero for new fs:USER sessions. The permissions/etc for fs:USER sessions are initialized via FS:Initialize(loaded from the user process exheader).
