If the supplied [[Filesystem_services#StorageId|StorageID]] is 1 (Host), a different set of internal functions is used to handle these commands. In this more restricted set of functions, GetControlNcaPath is stubbed and only returns error 0x608.
The Get* commands load the [[Filesystem_services|ContentPath]] from linked-lists' [[#Location_List_Entry|entries]] in memory using the input TitleID. When the command fails to find an entry for the specified TitleID, 0x408 is returned for GetProgramNcaPath and 0xA08 is returned for the rest.
The Set* commands always return 0 and add a new entry to the list. If a matching entry is found, it's removed first.
==== GetProgramNcaPath ====
Takes an u64 '''TitleID''' and a C descriptor. Used for [[NCA_Content_FS#NCA-type1|NCA-type1]].
==== SetProgramNcaPath ====
Takes an u64 '''TitleID''' and a X descriptor with a [[Filesystem_services#ContentPath|ContentPath]]. Used for [[NCA_Content_FS#NCA-type1|NCA-type1]].
Inserts a new [[#Location_List_Entry|entry]] with '''flag''' set to 0.
==== GetUserControlNcaPath ====
Takes an u64 '''TitleID''' and a C descriptor. Used for [[NCA_Content_FS#NCA-type3|NCA-type3]].
==== GetDocHtmlNcaPath ====
Takes an u64 '''TitleID''' and a C descriptor. Used for [[NCA_Content_FS#NCA-type4|NCA-type4]].
==== GetControlNcaPath ====
Takes an u64 '''TitleID''' and a C descriptor. Used for [[NCA_Content_FS#NCA-type3|NCA-type3]].
==== SetControlNcaPath ====
Takes an u64 '''TitleID''' and a X descriptor with a [[Filesystem_services#ContentPath|ContentPath]]. Used for [[NCA_Content_FS#NCA-type3|NCA-type3]].
Inserts a new [[#Location_List_Entry|entry]] with '''flag''' set to 1.
==== SetDocHtmlNcaPath ====
Takes an u64 '''TitleID''' and a X descriptor with a [[Filesystem_services#ContentPath|ContentPath]]. Used for [[NCA_Content_FS#NCA-type4|NCA-type4]].
Inserts a new [[#Location_List_Entry|entry]] with '''flag''' set to 1.
==== GetInfoHtmlNcaPath ====
Takes an u64 '''TitleID''' and a C descriptor. Used for [[NCA_Content_FS#NCA-type5|NCA-type5]].
==== SetInfoHtmlNcaPath ====
Takes an u64 '''TitleID''' and a X descriptor with a [[Filesystem_services#ContentPath|ContentPath]]. Used for [[NCA_Content_FS#NCA-type5|NCA-type5]].
Inserts a new [[#Location_List_Entry|entry]] with '''flag''' set to 1.
==== ClearLocationResolver ====
Takes no input. Frees all linked-lists' entries that have '''flag''' set to 0.
==== SetProgramNcaPath2 ====
Same as [[#SetProgramNcaPath|SetProgramNcaPath]], but inserts a new [[#Location_List_Entry|entry]] with '''flag''' set to 1.
==== ClearLocationResolver2 ====
Takes no input. Frees all linked-lists' entries that have '''flag''' set to 1.
