Running JaC64

JaC64 is a open source Commodore 64 emulator written in Java. I have many fond childhood memories of my C64, so I spent a little time fixing a couple of AWT issues and hacking together some sound support for ikvm. The sound patch is here, but it won't go in because it is essentially hard coded for JaC64 and even then it doesn't really work, because it turns out that .NET has no decent sound API. The only API available is SoundPlayer, but it has an unacceptable latency (and can only play one sample at a time, so you can't hide the latency). JaC64 generates samples that are 0.25 seconds long and then plays these back to back. This means that you hear sound, but it is very choppy.

Two obligatory screen shots, first the emulator application and second just the C64 screen of my favorite game:

OMG.. Krakout was SOO awesome. I even build a pot for it to use instead of the joystick. Good times!

I apologize for the lameness of this, but the comment spam was driving me nuts. In order to be able to post a comment, you need to answer a simple question. Hopefully this question is easy enough not to annoy serious commenters, but hard enough to keep the spammers away.

Anti-Spam Question: What method on java.lang.System returns an object's original hashcode (i.e. the one that would be returned by java.lang.Object.hashCode() if it wasn't overridden)? (case is significant)
