JSNES
As time progresses, canvas applications are becoming more and more impressive. Ben Firshman has written a rather impressive JavaScript NES emulator.
Rather than rewriting the game in JavaScript, JSNES emulates and reads the encoded ROMs displaying the screen within a canvas element.
Ben comments:
I got underway shamelessly porting vNES into Javascript. Although not the most efficient, it didn’t have any of the pointer memory mapping magic associated with emulators written in lower level languages. As such, it was more or less a direct port, bar a few tweaks to compensate for the lack of static typing, and obviously a rewrite of all the I/O.
A selection of the titles demoed.
As everything is happening in JavaScript, JSNES eats a lot of resource so it’s best to try in Chrome.
Please ensure you follow the relevant laws regarding ROMs for your country before trying this demo.

The fact that this works is utterly mindblowing. Of course, at about 4fps, iitit’s pretty unusable, but still, wow!
