→Auto-boot
After [[PMApp:GetFIRMLaunchParams|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 [[Configuration_Memory|UPDATEFLAG]] is set, NS will launch SAFE_MODE_FIRM with the application titleID set to the [[System_Settings#System_Updater|System Updater]] titleID for this region. When the UPDATEFLAG is not set, NS can auto-boot the following titles as well if [[Configuration_Memory|0x1FF80016]] bit0 is set.

When bit1 and bit2 are value zero in [[Configuration_Memory|0x1FF80016]], NS will [[NSS:LaunchFIRM|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. Otherwise when [[Configuration_Memory|0x1FF80016]] is value 2 and the output u8 from [[PTM_Services|PTMSYSM]] command 0x08140000 is value 0, NS will boot the title specified from the TWL TLNC block from FIRMparams+0x300. This is the same TLNC block which DSi titles wrote to RAM+0x300 for launching other titles via the launcher title. When handling the TLNC block, NS will boot the 3DS System Settings title when the TLNC titleID is the DSi System Settings titleID(the region field in the TLNC TID is not checked/used). When the TLNC titleID is not System Settings, NS will convert the input DSi titleID-high to the 3DS TWL titleID-high, then launch TWL_FIRM to run the title. NS does not support launching from gamecard via TLNC.
