Opera is ok too, but not brilliant.

Firefox users beware your machine will get bogged down! (Seriously you'll be waiting a long time before you see anything).

If you've got Internet Explorer don't even bother.

Cool!

I opened it with Chrome, but a popup message suggested I was using Firefox because my browser was too slow.

Oh dear, that's odd, how much cpu did it use?
Does it warn again if you refresh the page? (might just be cause it's downloading the images etc)

I've run it on a really crap 7 year old laptop and it ran full speed, with 90% cpu usage.

It worked just fine despite the message.

Wow, that's awesome!
Nice job. Is it based on a C64 javascript emulator or written from scratch?
I don't suppose javascript allows you to output generated sound...

(By the way: the title of this thread could have a few more superlatives! You're underselling it!)

I just took a couple of days of from my Java version of the emulator.
Completely based on my own work.

To be honest I just changed it last night with some pretty graphics, more carts, a bit of compression, and some work arounds for Opera issues.
So you're probably the only one who's seen the better one.

It just occured to me that those of you using firefox will probably not see anything unless you update the following setting.
Go to Firefox and type "about:config" in the address bar, then find the option "javascript.options.jit.chrome" and set it to true.
It'll still be unusable but at least you should see something.

And yeh, no chance of sound as that would really require some sort of activex control, or java applet to play the sound, which would be cheating!

Maybe someone could suggest it to w3c, considering how fast i've seen this run in Safari there is definitly enough clock cycles.

Where is the "C64 javascript emulator" ?
I've had a look round on the net, but all i can find are fakers.
i.e. things that don't emulate or run anything but make a screen that looks like a c64 that says syntax error for anything you type.

I don't know if there is one. And if not, all the better!

Since you're writing a Java emulator, have you seen JarVIC?
