Soon Chrome running inside Chrome.

I am using firefox 23.0, the program appears stuck at the decompressing step while showing 0 MIPS. Also restart with asm.js button doesn't appear to work.

Works for me on Firefox 23.0.1 after a fairly long delay. Also worked on Chrome 29.0.1547.66. Edit - one oddity: on Chrome the console does not register the spacebar.

You'll need to specify which version of chrome. Space works fine for me on Version 29.0.1547.66 m

This is cool but what is it good for?

Two things: 1) I am waiting for a version using networking. I know there are security issues but there are also workarounds. 2) My notebook is hot, so I checked and the Chrome CPU console is at 25% even if I am not doing anything in the console.

I'm curious about the CPU usage as well. The Chrome worker process on my system is pegged at 108% just sitting at an idle console :(

Still, this is extremely cool, especially seeing an architecture from the OpenCores project being used.

Technical merits and uses aside, I'm still floored that this kind of thing is even possible.

I've loaded it up and there's Monkey Island running on ScummVM running in a Linux VM running in Chrome's Javascript VM. Stunning.

How the heck does a 7MB image come with an entire OS, emulator, and a fully functional game?! You have to wonder how much of our stuff is bloated.

As written in the wiki, Firefox 23 is at the moment not a good choice. Firefox 22 emulates this machine three times faster and possibly Firefox 24 will return to this peak. Chrome is fine.

If this becomes a thing, I could dump nitrous.io and still code in browser.

I think the main issue is that the console and framebuffer use canvas elements which are continuously refreshed by a javascript timeout. This tends to use up all of a single core, no matter how little of the screen is actually changed. Perhaps using requestAnimationFrame could improve the CPU utilization.
