What tool do you open this thing with?

The briefcase setup uses some funky bolts that I don't have the tool for. What kind of weirdness is this? Both the deck and the base use these bolts. Info would be GREATLY appreciated.

Nevermind, I found it...tis a 4.5mm Gamebit. Might be useful to sticky this info...

I know the PCE Duo's use a Tamperproof T-10 bit.
