You really aren't a hacker. Try 'root' man....

Except that the author of original emulator is an asshole.
This is because he didn't release the source of it (its obscured javascript) and he nether licensed it under a free licence.

And author of this mod, who say that he obtained a permission to _host_ these obscured files just supports that bad guy.
Both should be ashamed of this. They didn't do a rocket science, nobody would want to buy this stuff.
