Hey there. I've just found a way to get into the whole web using the Nintendo 3DS's new YouTube app. Yes, just one day after its release, I've hacked the app. I'll cut to the chase and tell you how to do it.
Step One: Start the YouTube app.
Step Two: Press the menu button. (three stacked horizontal (left-to-right) lines, it's on the top-left of the screen when the page is scrolled to the top)
Step Three: Tap [Sign in]
Step Four: Scroll to the bottom of the page and tap "Help".
Scroll to the bottom and tap "Google" (it's to the left of "About Google" which is to the left of "Privacy & Terms".
Step Five: Congratulations, you've hit the Google Search Mobile page! Just tap OK or Cancel to close the text input window that pops up (it's because Google uses <input type="search"> and the YouTube app automatically pops up those.
Step Six: Search for stuff on the web.
3DSPaint actually works, although you can't type in textareas on any website (eg. the blog editor on 3DSPaint), basically anything which you can write more than one line of text in. You can use single-line text input boxes, eg. the Google Search box.
You may have to scroll to the bottom of whatever search result you tapped and tap "View page directly" to view the original page.
If you want to browse the web by URL, you can try out my experimental 3DS HackTube page, by Googling "site:jsafive.x10.mx" (without the quotation marks, naturally) and tapping the result with the URL "jsafive.x10.mx". Then tap "stuff", "3ds", "tubehack" and finally "browse.php". Tap the box, type a URL and then tap the "Submit" button. I'll add a simple page on jsafive.x10.mx with a direct link to the HackTube page soon.
For now, enjoy this cool trick!
Oh, by the way, it scores 176 out of 500 on html5test.com, it supports the <video> element and supports both the MP4 and H.264 codecs. You can view the full test results at http://html5te.st/af123b1cc23c2ad4. Pics coming soon.
Cya!
~jsa/out.
