"[[3DS_System_Flaws|System]]/[[3DS_Userland_Flaws|Userland]] security flaws fixed*": This includes known flaws, and any fixed flaws discovered via code bin-diff.
"[[3DS_System_Flaws|System]]/[[3DS_Userland_Flaws|Userland]] security flaws fixed*" and "3DS-mode homebrew affected" only apply to the changes done with that specific system-update("affected" does not include hax codebases breaking *just* due to updated codebins).
[[Category:Nintendo Software]]
== Auto-Boot Function ==
When the Home Menu is initially loaded by [[NS]], it checks the gamecard ExeFS:/[[SMDH|icon]] for the auto-boot flag. If the auto-boot flag is set, it will load the application on the cartridge and the home menu will not remain running in the background, or at least not in an operational state. Using software cues to return to the home menu, or sleep menu while in this state, causes a shutdown.
Notable features of demo titles:
*Auto-boot demos generally disable the functionality of the home button.
*The ''New Super Mario Bros 2'' demo, retained the functionality of the home button, and had an timer which triggered the demo to quit after a period of inactivity.
Auto-boot cartridges, can bypass some of the functions of the Home Menu. Auto Booted software:
{| class="wikitable" border="1"
* Doesn't show usage history in the [[Activity Log]]
* Bypasses Parental controls
* Bypasses Forced Game Card Updates
* Bypasses Initial 3DS Setup
* The console does not have a friends list presence.
* Is still subject to region lock(see below).
Region lock is still active, so the home menu will refuse to launch demos with incorrect region lock will not load, displaying "An Error has Occurred". However, game card update partition checks are not done, which allows launching demos that have region free encoding, but have an alternate(or even invalid) region update partition.
The following auto-boot paths can be used by Home Menu, checked in the same order listed below(the above gamecard auto-boot is checked before this):

|}
|}
== Region Lockout ==
One of the Home Menu's functions, is to regulate region lockout. The region lockout data for any given title is held in the [[SMDH#BNR Region|ICN data]]. There are 6 regions of which have their own region lockout, Japan, USA, Europe(including Nintendo Australia), China, Taiwan and Korea. There is also a value which makes a title exempt from region lockout, and consequently accessible from any region of 3DS.
The region-field stored in the [[SMDH|ICN-data]] is only checked when Home Menu itself launches a title, not when other titles use NS to have Home Menu launch titles. This isn't actually useful for gamecard region-free however, due to the gamecard system-updates, see below.
Also note that while some gamecard games are mostly region-free(main CXI is identical for all regions of the gamecard), those gamecards can't actually be launched with all 3DS regions due to the gamecard system-update, see below. Note that the main CXI being identical for all regions of a gamecard also means the savedata keyY is identical for all regions of that gamecard too(except for old system-version <v2.2 games, in some cases, due to different cardIDs).
== Home Menu [[Home_Menu/Themes|Theme]] SD [[Extdata|ExtData]] ==
=== Effects of Region Lockout ===
Every 3DS title regardless of location (NAND/SD Card/Game Card) is subject to region lockout scrutiny by the Home Menu. And the home menu treats 'out-of-region' titles by simply refusing to show them on the home menu. No messages are shown on the home menu to notify the user, the title is simply ignored. However out-of-region SD Card titles, will appear and quickly disappear, while all the SD Titles are being processed. In cases where access to the home menu GUI is not needed to launch the title (like in the case of kiosk demos), the home menu states an error has occurred, and launching of the title is stopped.
=== Game Card Updates ===
Either intentionally a region lock mechanism or not, the function which checks the game card update partition returns an error when it is detected the update is for a region other than the 3DS's region (Most likely triggered by the absence of the correct CVer title). And errors returned from checking the update partition, will result in the home menu displaying "This Game Card cannnot be used", when the user attempts to launch the title.
== Home-menu [[SpotPass]] usage ==
Home-menu originally used two domains with HTTPS for SpotPass. SpotPass stores this content in Home-menu's NAND shared extdata.
* The system notifications are downloaded from: <nowiki>https://a248.e.akamai.net/f/248/103046/10m/npdl.c.app.nintendowifi.net/p01/nsa/<regionID>/<filename>/<langcode>/<filename></nowiki> Where langcode is the two-character language codes from [[Config Savegame#Languages|config]], and regionID is from the below table. <filename> is bashoX/sysmsgX where X is 0-3.
* https://pls.c.shop.nintendowifi.net/pl/upload This URL is used for uploading data from the home menu NAND shared extdata, it's unknown what this is used for. This data is uploaded every 24 hours.
* <nowiki>https://npul.c.app.nintendowifi.net/p01/recv/<regionID>/<filename></nowiki> This is used for uploading unknown data from extdata. <filename> can be one of the following:
** "phu"
** "tiu" The POST data contains a list of [[BOSS_Services|BOSS]] taskIDs etc. This seems to be only for Nintendo titles?(system+eShop apps)
** "splu"
** "sendmgn" For this it appears SpotPass does a HTTP POST with data originally from Launcher.dat?

The SpotPass content payload for notifications begin with a header, followed by an [[SMDH|icon]] and the UTF-16 text, and various metadata.
=== VersionList ===
During startup, Home Menu loads "/versionList.dat" from NAND extdata 0xf000000e. This is downloaded via SpotPass, the file-data downloaded via HTTPS here is raw (no SpotPass container):
* Retail: [https://tagaya-ctr.cdn.nintendo.net/tagaya/versionlist]
* Dev-unit: [https://tagaya-dev-ctr.cdn.nintendo.net/tagaya/versionlist] The titles listed in this are not available on the [[Title list|normal]] CDN.
This is a list of title-updates available on the eShop, for regular app titles and update-titles. This is what Home Menu checks to determine whether the currently selected application needs to be updated or not. When an Internet connection is not available or wifi is disabled, Home Menu will skip VersionList handling/messages when you launch applications.

== Home Menu Themes ==
See [[Home_Menu/Themes|here]].
As of [[11.0.0-33]] Home Menu themes are only supported with USA, EUR, and JPN. CHN Home Menu was last updated with v7.0, and TWN doesn't even have a Home Menu settings menu(just the old screen brightness config menu + an [[amiibo Settings]] icon on the right side of the browser icon).
KOR Home Menu doesn't have the theme-settings menu button. While this does have the theme handling code, it isn't actually usable since extdataID 0x0 is used for theme-extdata for non-<JPN/USA/EUR> regions(which is invalid).

=== MngFile.dat ===
=== Cache.dat & CacheD.dat ===
These two files work in tandem to allow the home menu to cache icon data for applications which are presented on the Home Menu. The size of both files suggests a maximum cache size of 360 icons. Cache.dat stores details about the cache icon data, and CacheD.dat stores the icon data. The icon cache stores icon data for *all* applications shown on the Home Menu, this includes DSi NAND Titles, and DS(i) cartridges. The format of cached DS(i) icon data is not understood, but they are the same size as 3DS icon data (0x36c0).
In Cache.dat the first 8 bytes are a header where the first byte is the format-version, then follows each icon slots's entry in the format:
{| class="wikitable" border="1"

When saving a layout, the total layout field is increased, then a new layout entry is created with the contents of the current Home Menu [[System_SaveData]](NAND savedata) Launcher.dat + a screenshot of the main Home Menu screen is written. When loading a layout, Launcher.dat in savedata is written with the current Launcher.dat data already stored in memory(unknown if any data gets changed for it here), then data from the layout entry is copied into the Home Menu [[System_SaveData]] Launcher.dat.
|}
Home Menu *only* accesses this file with the Home Menu layout-settings menu / when entering that menu.
The icon arrays above are handled exactly the same way as Launcher.dat.
== Home Menu startup ==
When the theme cache is enabled via the above fields, Home Menu loads the cache at startup(if the used theme structure is valid).
The following is what Home Menu does at startup(converted from cmd-logs), from [[9.4.0-21]], in the same order Home Menu does it.

When the theme-type is value1 the themeindex must be <9. When the theme-type is value2 the themeindex has to be non-zero, and the u8 at offset 0x4 must not be >=10.
The theme-loader code (besides the AM <is-current-themeindex-DLC-installed> code) handles all theme-types >=2 the same way. However, it seems all DLC AM code involving checking the currently-used theme DLC only gets executed when the theme-type is value2. The code in the theme-loader for that also checks that a certain Home Menu state flag is non-zero, before running the AM DLC code(it's unknown where this flag value comes from).

|}
The Home Menu code for writing the updated SaveData.dat to FS is broken when the filesize is smaller than expected due to being from an older format-version originally. When writing to the file, Home Menu checks the filesize then attempts to use [[FSFile:SetSize]] on mismatch, but [[FSFile:SetSize]] can't be used with extdata(error from [[FSFile:SetSize]] appears to be ignored). When writing to SaveData.dat the write-size is the one for the current format-version, but since extdata files are fixed-size this will only result in the first {original filesize} bytes being written(result-code = 0xE0E046C1).
Basically, unless the extdata is deleted from the SD card FS manually, the SaveData.dat filesize will never be successfully updated from an old filesize to the current-format filesize by Home Menu.

The filesize must match 0x004D1280, otherwise the Home Menu code returns an error. The saved Home Menu layouts are stored here.
When saving a layout, the total layout field is increased, then a new layout entry is created with the contents of the current Home Menu [[System_SaveData]](NAND savedata) Launcher.dat + a screenshot of the main Home Menu screen is written. When loading a layout, Launcher.dat in savedata is written with the current Launcher.dat data already stored in memory(unknown if any data gets changed for it here), then data from the layout entry is copied into the Home Menu [[System_SaveData]] Launcher.dat.
Home Menu *only* accesses this file with the Home Menu layout-settings menu / when entering that menu.

The following is what Home Menu does at startup(converted from cmd-logs), from [[9.4.0-21]], in the same order Home Menu does it.
Originally Home Menu mounted sdmc in main(), starting(?) with [[6.0.0-11]] Home Menu only has sdmc mounted while handling [[SD_Savedata_Backups]].

=== Hardware reboot ===
During Home Menu start-up it uses [[APT:PrepareToStartNewestHomeMenu]]. If that doesn't return an error(normally NS returns 0xC8A0CFFC for that), Home Menu starts a hardware reboot with [[APT:StartNewestHomeMenu]] etc.
On retail this essentially means a hardware-reboot will automatically trigger if [[Configuration_Memory|configmem]] SYSCOREVER doesn't match FIRM_SYSCOREVER, or when the current APPMEMTYPE doesn't match the default APPMEMTYPE for this Old3DS/New3ds model. The latter can happen with running New3DS NATIVE_FIRM with Old3DS system-titles, for example.
