=== Video / libstagefright ===
 +
The browser manual includes licenses for Android and PacketVideo. The browser uses libstagefright from Android. Just like WebKit, the browser appears to use a very old version of libstagefright with security/other changes back-ported(for example, the v10.7 browser libstagefright codebase seems to be older than [https://android.googlesource.com/platform/frameworks/av/+/ec77122351b4e78c1fe5b60a208f76baf8c67591%5E%21/media/libstagefright/MPEG4Extractor.cpp this]). This codebase is missing certain chunk-parsing code for 3GP.
 +
 
 +
HTTP for libstagefright is internally handled with [[HTTP_Services|HTTPC]], with a similar(?) set of RootCAs as for browser-version-check.

The first version of the KOR New3DS browser was v9.6(which was when the New3DS KOR titles were originally added). Each version of the KOR browser has the same NintendoBrowser version as the other regions. The KOR browser has been only updated when the browser for the other regions were updated, hence the title-versions are the same as well. The KOR browser ExeFS .code is different from the other regions(more than just region-related IDs etc).

==== v10.6 ====
 +
The ExeFS codebin was updated.
 +
 +
[[browserhax|browserhax_fright_tx3g]] was fixed. The code handling tx3g now matches the latest libstagefright git.
 +
 +
Hence the below RomFS listing, no OSS was updated at all(besides libstagefright mentioned above).
 +
 +
The following RomFS files were updated:
 +
/build/buildinfo.dat
 +
/static.crs
 +
 +
==== v10.7 ====
 +
Basically the same changes as Old3DS v10.7, except with the usual buildinfo.dat update in RomFS. The below date is 6 days after the browser-version-check [[3DS_Userland_Flaws|bypass]] was publicly disclosed.

 +
  /build/buildinfo.dat

Minus the 4 functions that changed due to compiler optimization, only 1 function was actually updated. This is LT_1a4004, previous version at LT_1a4004: libstagefright status_t MPEG4Extractor::parseChunk(off64_t *offset, int depth)
 +
 +
Additional code was added which doesn't seem to be from upstream git, right [https://android.googlesource.com/platform/frameworks/av/+/32d6e5f0ebe9e00f80401e5f4fd6e285a474590d/media/libstagefright/MPEG4Extractor.cpp#880 before] the cprt code block: "if((*offset + chunk_size) - data_offset < 0)fail"
 +
 +
This fixed skater31hax + any other mp4 haxx which requires using a negative 64bit chunk_size value.
 +
 +
The filepath base used in the assert strings were changed from "d:\Jenkins\workspace\MPSkaterBuild\MVPlayer\Skater\Base\Android\frameworks\base\media\libstagefright\" to "d:\jenkins\workspace\MPSkaterBuild-Git\Base\Android\frameworks\base\media\libstagefright\".
 +
 +
==== v11.4 ====
 +
The only changes in RomFS was for "/build/buildinfo.dat" and "/static.crs", hence no OSS in CRO(s) were updated.
 +
 +
The main codebin was updated. Exactly two functions were updated, these are not related to code exec vulns.

==== Gamepad ====
 +
The browser's now-outdated gamepad API provides information about the states of the circle pad, C-stick, and every button aside from the Home and Power buttons. The gamepad, which has an ID of <code>New Nintendo 3DS Controller</code>, is contained within the array returned by the <code>navigator.webkitGetGamepads</code> function.
 +
 +
Both of the gamepad's arrays, which contain the states of various inputs, seem to be reconstructed each time they are accessed via their gamepad object. It is not known if the values within the arrays can update upon each access of the array, but the values <em>can</em> update frequently enough to obtain accurate readings of the system's controls.
 +
 +
===== Axes =====
 +
The gamepad's <code>axes</code> array contains four floating-point numbers in the following order:
 +
 +
{|class="wikitable" width="20%"
 +
! Index !! Axis
 +
|-
 +
| 0 || Circle pad X
 +
|-
 +
| 1 || Circle pad Y
 +
|-
 +
| 2 || C-stick X
 +
|-
 +
| 3 || C-stick Y
 +
|}
 +
 +
Each coordinate ranges from -1.0 (left/up) to 1.0 (right/down). Neutral position is indicated by 0.0. Drift and/or inaccurate calibration may make these exact values unattainable.
 +
 +
===== Buttons =====
 +
The gamepad's <code>buttons</code> array contains numbers for the following numbers:
 +
{|class="wikitable" width="20%"
 +
! Index !! Button
 +
|-
 +
| 0 || B
 +
|-
 +
| 1 || A
 +
|-
 +
| 2 || Y
 +
|-
 +
| 3 || X
 +
|-
 +
| 4 || L
 +
|-
 +
| 5 || R
 +
|-
 +
| 6 || ZL
 +
|-
 +
| 7 || ZR
 +
|-
 +
| 8 || Select
 +
|-
 +
| 9 || Start
 +
|-
 +
| 10 || Unused

 +
| 11 || Unused

| 12 || Up
 +
|-
 +
| 13 || Down
 +
|-
 +
| 14 || Left
 +
|-
 +
| 15 || Right
 +
|}
 +
 +
Each button's value is 0 while the button is not pressed, and 1 while the button is pressed.
 +
 +
Based on the Gamepad API's specifications, buttons 10 and 11 are reserved for left stick presses and right stick presses respectively, which the 3DS does not support.
 +
 +
==== Notes ====
 +
* Viewport information can be specified with the <meta> element.
 +
* The html "color" <input> type is not supported.
 +
* 3D images appear as their right-eye image within webpages.
 +
* Webpages are locked to the bottom screen when zooming is disabled, the webpage's initial scale is 1, and the entire webpage can fit within the bottom screen's dimensions (320x212).
 +
* Interactable elements that are positioned partially outside of the bottom screen can temporarily be moved further inside the bottom screen by tapping them with the touchscreen.
 +
* Favicons can be changed using Javascript, but they become unchangeable once the document's <em>readystatechange</em> event finishes firing with a ready state of "complete".
 +
* Focusing on text-editable elements via Javascript will always open the keyboard.
 +
* Webpage content is usually rendered at 30 FPS despite the <code>webkitRequestAnimationFrame</code> function allowing code to run at a rate of 60 FPS.
 +
** As a result, display-related routines may only show half of their intended updates.
 +
** This issue can be mitigated by rendering on every other frame. However, various factors (such as touchscreen input and sleep mode) make this fairly inconsistent.

=== v10.7 ===
The gamecard v9.9 sysupdate included with some games contains a dummy Old3DS/New3DS web-browser. The *only* thing this title does is display the same message listed in the above forced-update section. The message files in RomFS *only* contain that message string above. There are no "http" strings in the main codebin, and [[RO_Services|RO]] isn't used either(no CRO data in RomFS at all). Both browsers are internally called "dummySpider".
+
The only actual code change with Old3DS/New3DS browser v10.7 was that the code which calculates the diff_timestamp was moved to immediately after the block which initializes <state_timestamp> when <state_timestamp> is all-zero. This fixed the browser-version-check [[3DS_Userland_Flaws|bypass]].
   −
Hence, if you update your system from pre-v9.9 using a gamecard with v9.9, the system web-browser will be rendered *completely* useless until you install a system-update from CDN(no network requests involved here).

== Dummy web-browser ==
 +
Gamecards v9.9 and above include, with their sysupdate, a dummy Old3DS/New3DS web-browser. The *only* thing this title does is display the same message listed in the above forced-update section. The message files in RomFS *only* contain that message string above. There are no "http" strings in the main codebin, and [[RO_Services|RO]] isn't used either(no CRO data in RomFS at all). Both browsers are internally called "dummySpider".
 +
 
 +
Hence, if you update your system below v9.8 with any v9.9 or above gamecard, the system web-browser will be rendered *completely* useless until you install a system-update from CDN(no network requests involved here).
 +
 
 +
Gamecards v10.7 and v11.4(New3DS only) have updated the dummy web-browser, where the only difference is the title version.

When an update is detected this timestamp is negative, otherwise this is a normal positive timestamp(it's unknown how exactly this timestamp is checked). When positive, this seems to be the last time the forced-update HTTPS request was done where no update was needed.

 +
 +
The Old3DS browser dispatches a <em>keypress</em> event once per key press for each of the buttons above, but the New3DS browser dispatches the event continuously until the button is released.
 +
 +
A keyboard event's <code>keyIdentifier</code> property usually should not be used to identify which button was pressed, as the A button's <em>keypress</em> event is dispatched with a key identifier of "" (an empty string) rather than "Enter" in the New3DS browser.
 +
 +
The New3DS browser's keyboard dispatches <em>keydown</em> and <em>keyup</em> events when a key is pressed, but it is not possible to determine which key was pressed based on the event itself. Every keyboard <em>keydown</em> event has a key code of 229 and a key identifier of "U+00E5", and every <em>keyup</em> event has a key code of 0 and a key identifier of "U+0000".
 +
 +
Key events are suppressed while the touchscreen is touched.
    
==== Touch/Mouse Events ====
 
==== Touch/Mouse Events ====
<em>onmousedown</em>, <em>onmouseup</em> & <em>onclick</em> are all triggered by the browser.  However, the <em>onmousedown</em> event doesn't trigger until you lift the stylus or you've held it on the screen for ~2 seconds—which is when text selection mode is activated—making it pretty much the same as <em>onmouseup</em>. The events cannot have their default action cancelled.
+
The <em>mousedown</em>, <em>mouseup</em>, and <em>click</em> events are all triggered by the browser.  However, the <em>mousedown</em> event doesn't trigger until you lift the stylus or you've held it on the screen long enough to trigger text selection mode.  Text selection mode requires pressing the touchscreen for approximately 1.05 seconds in the Old3DS browser, or pressing the touchscreen for approximately 0.41 seconds in the New3DS browser. Also, the <em>mousedown</em> event is only dispatched while text selection mode is active. Mouse events cannot have their default actions cancelled.
 +
 
 +
Touch events are not supported in the Old3DS browser, and the <em>touchcancel</em> event does not seem to be used by either browser. Touches cannot start within the bottom browser bar, but they can move to be within it. The rotation angle, contact radii, and pressure of each touch are always zero, as the 3DS touchscreen is not capable of detecting these values. Only one touch can be detected at a time due to the touchscreen's hardware limitations as well. Unlike mouse events, touch events can have their default actions cancelled. Doing so will prevent the touchscreen from being used to scroll through the webpage, highlight text, zoom out, and interact with the bottom browser bar.
   −
The <em>onmousemove</em> and common touch/gesture events are not supported.

The [[System_Font#Unicode_Private_Use_characters|system font]]'s private-use characters can be viewed within the web browser.

The touch screen resolution is 320×240. However, the viewable area in the browser is <b>320×212</b> <em>or</em> <b>320×240</b>, depending on if the bottom browser bar is visible. The New3DS browser's bottom bar can hidden by scrolling and/or attempting to zoom in/out with the C-stick, unless scrolling and zooming have both been disabled.

You can have a page span both screens. However, the browser will behave as if the bottom screen is the only active screen and the top screen is scrolled off. This is important when computing CSS coordinates. Items positioned from "bottom" will be positioned based on 220px and not the full 432px of both screens.
