For your consideration, here is the Nintendo DS Dreamer Series Teacher Simulation Cartridge, no. NTR-CVSE-USA, from Nintendo, 2009, complete with instruction manual, registration card, safety sheet and case, made in Japan.  I have not tested the cartridge.  The cartridge and paperwork are in nice shape.  The manual has 39 pages.  The case has some wear and a few small dents marks on the back of it.  It will be mailed in a box for protection.  Item pictured is the actual item up for sale and comes from a non-smoking household.  (653.2b23b-.9bb)
