Nintendo emulator online in Java

Bubble Bobble, Super Mario Bros, Excitebike, 1942, and more...

This is the first time I've seen a NES emulator online before. It's a Java applet so you'll need a web browser that supports it. Sadly the controls aren't configurable. I wish they were so I could have the arrowkeys under my left hand and the A- and B-button under my right.
