Super Game Guy
Two historic lines of portable Nintendo consoles, decades of games. Both had reigns of similar length (15 years for GB/C/A, 13 years for DS/3DS) before a new console family debuted.
For the purpose of this thread, no Virtual Console titles for 3DS allowed, that's too easy, but ports/remakes are fair game. So the Super Mario Advance series counts for the GBA, and OOT/MM 3D counts for 3DS.
