It seems the copy of sk kongregate uses for macs doesn't like java 7. Not to mention google chrome has java 7 unsupported so you can't boot it inside chrome anyhow.

Tried it in all browsers at all security levels for java 7, nerp. I also don't even get that fail message most of the time, just a flash of a white window the repeatedly opens and closes.

Edit 2: Ignore the GBA CPU debugging going on in the background ._.
