 If payload-loading would be implemented in wiiuhaxx_common itself at some point, then the payload-heap-addr mentioned here wouldn't be needed/matter anymore.
 
-Supported system-versions for "browserhax_fright_tx3g_wiiu.php"(Internet Browser 5.5.1 fixed the vuln used by this):
+Supported system-versions for "browserhax_fright_tx3g_wiiu.php":
 * 5.3.2: This isn't fully supported since the payload-heap-addr is off.
 * 5.4.0
 * 5.5.0
+* 5.5.1: Originally this exploit was thought to be fixed via doing manual code-RE(hence why it was released when it was). However, that was actually wrong due to misreading that code: this exploit works fine as-is on 5.5.1(no testing on 5.5.1 was done before release, only code-RE).
 
 To use this you must host the exploit script on a server, then you must setup wiiuhaxx_common as documented in that repo. If you're going to use libwiiu with your payload binary, then you must use a coreinit.h which actually supports your system-version. The max size of the final payload(loader included) is 0x4000-bytes, so your input payload max size is a bit less than 0x4000-bytes(the script will throw an error if the size is too large). Once all setup, just access an URL like the below one where "browserhax_fright_tx3g_wiiu.php" is hosted, with the browser.
 
 Note that issues occur when the final URL you use is too long, so you should keep it short like with the following: "http(s)://{server}/wiiuhaxx.php?sysver={version listed in wiiuhaxx_common}". This hasn't been debugged yet.
 
 The only known time this exploit has ever failed pre-native-code-exec(on a supported system-version), was when the URL was too long as described above. However, this is mostly with testing with just one open tab(in particular with automatically loading the page).
 
+# Browser HTTP(S) URLs
+As of 5.5.1 the only HTTP(S) URLs for code-binaries under Internet Browser "code/" are: internal-testing URLs, web-searching, "favorites" URLs, the Wii U version of the browser-filter also used for JPN-New3DS(https://3dbrew.org/wiki/Internet_Browser#New_3DS_Internet_Browser), etc.
+That is, as of 5.5.1 there's no known Wii U equivalent to the following with 3DS: https://3dbrew.org/wiki/Internet_Browser#Forced_system-update
