The NS system module is the first module launched from a NAND title after the core processes sm, fs, pm, loader, and pxi are loaded. This module is launched by the pm process, with the titleID loaded from REG_NSTID. NS first launches ErrDisp, then the menu. On retail the menu TID is loaded from REG_MENUTID, while on dev/debug the menu TID is loaded from config. The TID of the launched menu is then written to REG_ACTIVEMENUTID. NS uses pm:app to launch titles.

Like home menu NS is constantly running while the system is in 3DS-mode.

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 normally doesn't exist on retail.

NS service "ns:s"
