Just wondering how much this is supposedly, I'm seeing different prices and different models. I checked on ebay/looked around the internet a bit and supposedly I got a rare model, just wondering if someone has more info on this. 

Interested myself because I also have one of these in the box (sealed, IIRC). I have about 6 of them. FWIW, these can be Jailbroken and used to boot Swiss and GB Interface, but you need a modded GC to get started and it's not nearly as refined as other methods (Datel SD Media Launcher, for example).

Who needs a Game Boy Player Start Up Disc?
