i saw this eBay lot just now and noticed the cart in the lower right hand corner is an M Network "Lock 'N' Chase" cart........but its a really small case (half the size of a normal M Network cart)?!?!?!?!?!? Is this rare? Is it a homemade case? Did Mattel Electronics actually make them like this one? If so, I've NEVER seen one like it before today!
Wiki has listed for Lock N Chase:
3DS Virtual Console
its not "Telegames" version (standard Atari shaped cart with silver foil label), its not Intellivision edition (actual rectangle shaped), can't find an Apple II version on the net, and its not Game Boy or newer..........
