Nintendo Switch browser capabilities
Abstract
Don't get your hopes up
Body
Before the Switch, Nintendo had a nifty HTML5 framework for game
development called Nintendo Web Framework. It used to have its own
page on Wikipedia, no idea where it disappeared to.
Anyhoo, I was looking forward to its return so I could make games for
the Switch using my existing skillset. Due to Nintendo's enthusiasm
for the Unity and Unreal game engines, it doesn't seem like that's
happening anytime soon if ever, much to the chagrin of aspiring game
developers (and Switch owners) like myself. However, I was curious to
know what the built-in browser is capable of. Here's what I found[1],
with my Switch's OS on version `4.0.1`:
1. Parsing Rules
- ✅ `<!DOCTYPE html>` triggers standards mode
- ✅ HTML5 tokenizer
- ✅ HTML5 tree building

And so…
The Nintendo Switch browser scored 339 out of 555 potential
points. Not bad for browsing but it certainly isn't equipped for
game development. Lack of support for WebGL, WebM, the Web
Animations API, and IndexedDB certainly inhibits the kinds of
games you could make, so this might explain their silence on the
NWF front.
Oh well.
If you have a Switch and want to see these results for yourself,
here are the steps needed to access the web browser:
1. Go to `System Settings` > `Internet` > `Internet Settings`
2. Select the network you want to join or are already connected to
3. Select `Change Settings`
4. Select `DNS Settings` and choose `Manual`
5. Under `DNS Settings`, select `Primary DNS`
6. Replace the contents with `045.055.142.122` and hit `OK`
7. Save!
8. Connect to the network you just modified DNS settings for, and
you should see a message saying "Registration is required to
use this network"
9. Proceed and you'll be redirected to Google, where you can
search for DuckDuckGo and use that search engine instead
Extra stuff
The useragent Nintendo is going with is `Mozilla/5.0 (Nintendo
Switch; WifiWebAuthApplet) AppleWebKit/601.6 (KHTML, like Gecko)
NF/4.0.0.7.9 NintendoBrowser/5.1.0.15785`. I am SO glad their
useragent isn't the usual fugly spaghetti soup that most browsers
come up with. The screen size is 1280 by 720.
I remember when people made websites for the Nintendo DS, back
