== NeedsUpdateVulnerability == | |||
No input, returns an output u8 bool flag. | |||
Web-applets use this command to check if the system needs an update. | |||
== UpdateSafeSystemVersionForDebug == | |||
Takes an input u64 '''titleID''' and an u32 '''version'''. | |||
This command is not available for retail units. On a debug unit, if the [[System_Settings|system setting]] <code>vulnerability!enable_debug</code> is set, this mounts the system savegame [[Flash_Filesystem#System_Savegames|0x8000000000000049]] as "ns_ssversion:/", opens the file "ns_ssversion:/entry" and writes the supplied '''titleID''' and '''version''' in it. | |||
Finally, it calls [[NCM_services#ncm|OpenContentMetaDatabase]] with [[Filesystem_services#StorageId|StorageID]] 3, then calls [[NCM_services#IContentMetaDatabase|GetLatestContentMetaKey]] with the supplied '''titleID''' and compares the version field from the returned [[CNMT#Content_Meta_Records|Content Meta Record]] with the supplied '''version'''. | |||
If the supplied '''version''' is higher than the one in NCM's database, the value returned by [[NS_Services#NeedsUpdateVulnerability|NeedsUpdateVulnerability]] is set to "true". | |||
== GetSafeSystemVersion == | |||
No input, returns an u64 '''titleID''' and an u64 '''version''' as a 0x10 byte array. | |||
