I finally get one of these things, and I can't get it to work. I tried it in a GB Pocket, original GB, and Super GB and all I got was the Nintendo logo on all 3 (it stayed at the Nintendo logo after startup)

It says it's for GB Color and GB Pocket games, so my best guess is that I need a GB Color, but before I spend the cash on one I wanted to ask here if this is a fixable problem.
