The emulator features a built in soft-controller, and the games can be played in either portrait or landscape mode. Check out the following video review:
To use webNES, you’ll need to go to webn.es via your mobile browser, as it won’t allow you to use a normal desktop browser (though I’m sure that can be easily worked around). There are a couple of built-in generic games, but you probably don’t care much about them. Once at the main webNES interace, you can tap the ‘+’ sign in the upper right-hand corner to link your Dropbox account. Your Dropbox account will need to contain an NES rom to add to webNES. Once you add your NES rom, simply tap on the name of the game to play.
You can link your dropbox account to load ROMs for games that you own.
The experience is very jittery at times, but for a game running in the stock Safari browser, it’s still a sight to be seen in person. I highly recommend that you try this out if you have any legit NES ROMs laying around.
As far as sound goes, you won’t get any sound out of your iPhone’s speaker, but sound does work when you hook up a pair of headphones. Like the gameplay itself, sound was a bit choppy, as the games don’t exactly run at 100% speed.
Apparently, webNES works with any mobile browser, not just Safari, so if you’re running an Android device, you can join in the fun as well. Ultimately this won’t be something you can use to really play games due to its choppiness, but it’s a cool technical demo nonetheless. Hopefully whoever is behind the project will continue to improve it, and make it into something that’s useable long-term. What do you think about this awesome browser-based emulator? Pretty cool, no?
