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 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.

Fantastic. I love that it's OpenRISC based rather than the "obvious" choice of yet another x86 emulator. And framebuffer support, though slow.

Bellard's jslinux, despite being pretty impressive too, is not open-source.

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.

Yes, at least for me on Firefox 23

From the project wiki:

'In the beginning google Chrome was the fastest. After more and more optimizations were implemented Firefox was little bit faster then Google Chrome. When IE10 became compatible with my code it was the fastest. After implementing the worker thread Firefox 22 got superior being 3 times faster then the other browsers. For some reason this advantage got lost with Firefox 23. Instead of this Google Chrome managed with version 29 to get this position with 30-50 MIPS. At this moment changing one line of code in the Step() function could reduce or increase the speed by a factor of 3. The reason for these speed oscillations is the tremendous complexity of todays JIT compilers and the black box behavior of them which makes it almost impossible to code really fast code.'
