Nintendo Switch does not have a normal Internet Browser for user usage. However, there is multiple browser applets. It is the [https://web.archive.org/web/20170304075230/https://gl.access-company.com/news_event/archives/2017/170303/ NetFront NX] browser, which is based on Webkit.

When linking the Nintendo Account with Facebook, the Facebook Auth website will open, offering a search box that can be used to browse the Internet ("LoginApplet"). Alternatively, it can be accessed with [https://gbatemp.net/threads/web-browser-kind-of-on-the-switch.463094/ custom DNS settings] which simulate a Wi-Fi login page ("WifiWebAuthApplet" for captive-portal).

The full UA for Switch and Switch 2 are similar, on matching system-versions. The NF and NintendoBrowser versions are newer for S2 however.

[8.0.0+] <code>malloc</code>/<code>operator new</code> now checks the return-addr (addr located in a relevant NRO), with wkc_malloc_crashonfailure being called for the allocation if the check passes, otherwise a normal allocation is done (the code which runs for this will Abort if allocation fails).

[12.1.0+] The size is now passed directly (64bit) without using sxtw.
 
[11.0.0+] There's now optional code for using [[SVC|svcMapPhysicalMemoryUnsafe]] etc, however it's unknown what sets the flag for this. An Abort string used this is: "{path}/TransferredMemoryManager.cpp"

TransferMemoryEnabled: sdknso only exposes this for the Web applet. The sdknso func uses <code>nn::os::QueryMemoryInfo</code> at the start of the func, however the output is unused. The applet doesn't seem to parse this TLV.
