Apparently, someone found a copy of the Glucoboy from when they were a kid:
These things unbelievably rare. They basically shouldn't exist. Like at all.
When Bayer bought up Guidance Interactive, they destroyed all of the old Glucoboys because they wanted to make a newer version specific to the DS.
It's crazy that something like just is still around. The Glucoboy is so rare that a few years ago, some folks didn't believe it was actually ever released.
