NS and APT Services: Difference between revisions

The NS ('''N'''intendo User Interface '''S'''hell) system module is the first module launched from a CTR-NAND title after the [[FIRM]] processes are loaded (also see [[Bootloader]]). This module is launched by the pm process, with the titleID loaded from NS state(hard-coded TID initialized during applet TID-array initialization). NS first launches [[ErrDisp]], then the menu. On retail the menu TID is loaded from NS state, while on dev/debug the menu TID is loaded from [[Config_Savegame|config]]. On dev-units if the menu TID block doesn't exist in [[Config_Savegame|config]], NS will attempt to launch the alternate menu instead. The TID of the launched menu is then written to [[Configuration Memory|ACTIVEMENUTID]]. NS uses [[PMApp:LaunchTitle|pm:app]] to launch titles.

NS will only execute this code-path when [[Configuration Memory|0x1FF80016]] is value zero, when KERNEL_VERSIONMAJOR is value 2, and when KERNEL_VERSIONMINOR is less than 35. Therefore, this code-path is only executed when the running NATIVE_FIRM version is prior to [[5.0.0-11]].

The maximum sessions that can be used with this service is two, therefore only two processes can use this service at the same time.

=NS Power Service "ns:p"=

{| class="wikitable" border="1"

This was added with [[3.0.0-5]]. The PTM sysmodule connects to this service, and syncs whenever [[PTM|ptm:s GetShellState()]] changes.

This is [[NSS:SetWirelessRebootInfo|setup]] by the dlplay system-application, before launching the DLP-child which can then use [[APT:GetWirelessRebootInfo]]. The MAC address and passphrase is used for connecting to the host by the DLP-child. See also [[DLP_Services|here]].
