Well I guess we have officially crossed the bridge, where multiple Ghz machines can run scripts that can emulate a 1.8Mhz 6502 in realtime.
And frankly the bigger thing to behold is just how FAST Google chrome is at java script. On my Intel Centrino laptop the google benchmark (http://v8.googlecode.com/svn/data/benchmarks/v5/run.html) scores 105 in Internet Explorer 8, while Google Chrome scores 3330.
That’s not a typo, Google Chrome is more then 31x faster than IE at executing Java Script.
I’ve got to find out where that whole NaCL thing went to, and where it is.
But seriously, go check it out! Mario in a browser without flash!
