The only difference between the ExeFS .code for each region of the Old3DS/New3DS browser, is byte values for the title uniqueID/region.

Video decoding is done with [[MVD_Services|mvd:STD]]. Audio decoding/playback is done with a browser-specific DSP binary. The Old3DS browser used CSND for audio playback, the New3DS browser doesn't have access to that at all since it uses DSP instead.

=== 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).

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.

=== 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).

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).

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.
