About Netsurf 3DS
The 3DS's own browser stops at TLS 1.1 and mangles a lot of pages. This port handles TLS 1.2 and supports HTML and CSS. JavaScript is switched off, SVG and WebP don't work yet, and you can't download files to the SD card yet.
You also need the resources.zip package from the releases page, extracted to /share/netsurf on the SD card. It won't run properly without it.
Type file:/// as the address to browse the SD card and open text, HTML and image files. nsfb_himem.cia runs in the 80MB high-memory mode.
Text often gets cut off or wraps wrong, bigger images distort while you scroll, and you can't view a site's certificate. The author doesn't expect it to ever play YouTube or run web apps like Google Docs or Discord.
