Woohoo! I managed to compile it with Netbeans 6.1. I made a new project and added the sources. The compiler then complained about JOrbis missing.

I downloaded JOrbis here: http://www.jcraft.com/jorbis/
Unzipped and put it the /src folder of BugBomb.

Then it complained about JNLP missing. I found the jnlp.jar file on my system in
/java\jdk1.6.0_10\sample\jnlp\servlet
Then I added it to "Libraries" in Netbeans.

Then Bugbomb quickly compiled and ran! Thanks for the source!
