So I bought a Project Diva Arcade Future Tone cabinet that seems to play just fine. All the lights and controls work. I noticed the key chip is missing. And trying to goto into one of the service menus it shows the hardware is a NU2 (i thought they were all NU1 or ringsomething). So doing research has led me here. Any one have any idea what is going on with this thing to make it work without the key chip. I don't want to brick it if its working.
