I've been digging into the features of the Nintendo 3DS browser today and have a list of what I have discovered so far.
Acid Tests Acid3: 90%
Acid2: A few colors misplaced
Acid1: Passes
CSS border-radius
2d transformations
NO text-shadow
HTML5 Canvas 2d-context
NO audio
NO video
NO geolocation
NO Web Sockets
NO WebSQL
JavaScript A-button, D-Pad input
AJAX
NO mousemove (meaning no painting)
Extra MPO images viewed as 2D thumbnails and 3D stand-alones
MPO uploads from SD Card
MPO downloads to SD card
I will continue digging...
UPDATE There is support for mousemove and canvas drawing. I was unable to initially get the DSiPaint app working on my 3DS until I realized that the canvas was just not refreshing. By changing any CSS style on the canvas, it will force a refresh, and everything works!
Damnit...excuse my language...but why didn't Nintendo make room for Flash, sound, etc.? The 3DS Browser is almost exactly like the DSi Browser. Nintendo should've made things different during the production of the Browser.
@drwho The main complaint is that ACCESS left basic features out of its browser that were in the DSi's browser.
Now, hopefully ACCESS will be kind and update it promptly.
Nintendo doesn't want us to use the browser other than for the Basic, they are forcing the costumers use the Features on the 3DS and not customizable stuff. Like 3DS Made websites? Yeah...
No text-shadow could mean my eyes will last me another year considering all the noobs with blue-on-purple text. -.-
Furthermore, while the Browser, may fail, remember... Now, this might shock some of you, but... IT'S A HANDHELD GAMING SYSTEM. All of you are too focused on the Browser. It'll probably be updated, or all-together trashed and replaced. Be happy, patient, and focus on the gaming portion of your $250 investment. -.-
*sigh* the only reason I wanted the 3DS was for the improved graphics and internet... And by the looks of things, they have done worse on the browser than with the DSi. [sarcasm] Nice job Nintendo. [/sarcasm]
@snaker No, incorrect. The 3DS web browser lacks several features because ACCESS sucks at making good browsers. I mean, they did make the slow as molasses PSP browser.
