I'm testing in Firefox 24. If you could tell me what the error console outputs, I'll try to fix it.

Thanks, it's under the error tab: ReferenceError: requestAnimationFrame is not defined http://copy.sh/v24/v86_all.js Line: 239

Update to a newer Firefox. Your FF is dead old and doesnt support the new HTML5 methods... and @author, maybe add a polyfill?

It actually boots on Chrome.

On Android.

Then it usually dies for low memory - and I can't enter anything at all without keyboard (which doesn't pop up) - but still. The fact that I can boot up a x86 emulator in javascript in browser on ARM mobile phone is crazy.

FF 24 is the latest stable. FF's docs say they added this function in FF 4.0, which was several years ago. So it's a bit more complicated than you make it out to be.

EDIT: I thought FF24 wasn't working, turns out I was confused between my Linux desktop's and Mac laptop's FF versions. Sorry!

I'm trying to run a custom basic x86 kernel (it was an assignment for my Computer Architecture course). But I can't get it to work =/. (This image works with bochs and in a virtual machine without problems). It seems that it can get to protected mode, enable interruptions, enable paging, but it fails loading the tasks =/

This is the error that I'm getting:

Unimplemented: load system segment descriptor, type = 9 Execution stopped

With emscripten, anything is possible nowadays. And it blows your mind.

Anything has been possible since 1999. Anything at all. http://www.zombo.com

I can't stop laughing. That was so weird and funny that I almost forgot what I was doing here on HN.

Works for me on Firefox for Android, no crashes yet.
