The NS system module is the first module launched from a CTR-NAND title after the FIRM processes are loaded. This module is launched by the pm process, with the titleID loaded from NSTID. NS first launches ErrDisp, then the menu. On retail the menu TID is loaded from MENUTID, while on dev/debug the menu TID is loaded from config. On dev-units if the menu TID block doesn't exist in config, NS will attempt to launch the alternate menu instead. The TID of the launched menu is then written to ACTIVEMENUTID. NS uses pm:app to launch titles.

Like home menu NS is constantly running while the system is in 3DS-mode. When attempting to return to home-menu when the home-menu process isn't running(like when the process terminated/crashed), NS will trigger a fatal error.

Alternate menu

When launching the regular menu fails, NS will then attempt to launch the alternate menu. This title could be used as a recovery process, however it's normally not used after the factory. This title is used at the factory for installing system titles, this title seems to be installed from a factory gamecard. This installer title likely deletes itself from NAND once it's finished installing titles.

Auto-boot

After loading FIRM params and prior to launching ErrDisp/Home Menu, NS handles auto-booting titles. The same code called by APT:Reboot is used for launching FIRM here. When the UPDATEFLAG is set, NS will launch SAFE_MODE_FIRM with the application titleID set to the System Updater titleID for this region. When the UPDATEFLAG is not set, NS can auto-boot other titles as well if 0x1FF80016 bit0 is set.

When bit1 and bit2 are value zero in 0x1FF80016, NS will launch the title specified by the FIRM parameters if the title-info is set. This FIRM launch is done after launching ErrDisp and Home Menu.

NS Workaround

A "ns_workaround" was added in NS to workaround the flaw added with 5.0.0-11. When NS is loading before launching any ARM11 processes and certain Configuration Memory fields are set, NS will launch AM then use command AM:InstallNATIVEFIRM. NS will then execute the code called by APT:StartNewestHomeMenu, the code related to APT:PrepareToStartNewestHomeMenu is not executed here.

NS will only execute this code-path when 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_FIFM version is prior to 5.0.0-11.

0x00070042 1.0.0-0 - 2.0.0-2 This does initialization for the gamecard system update. Then this checks whether this gamecard system-update needs to be installed, by comparing the title-version of the CVer CIA stored in the system-update CFA with the title-version of the CVer title already installed in NAND.
0x00080000 1.0.0-0 - 2.0.0-2 This shuts down the gamecard system update interface: the shared memory is unmapped, the CFA archive is closed, state is cleared, etc.
0x0009.... 1.0.0-0 - 2.0.0-2 Gamecard system update related.

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