Before I say anything I want to make myself clear that I do NOT support hacking into a company's embedded system to expose hidden modes, soundtracks, animations, etc. I, like many other tinkerers, do believe in exploring something just for the sake of doing it, even if you have a benign goal, such as listening to custom music while you play.
So, anyone getting Wizard of Oz willing to try getting in to the system? I'm going to give this thread a try. I don't want technical details of how to exploit a Linux weakness and gain root access, just curious to know if there is any interest. Don't want this topic to go south.
