Hello? Did you die at your keyboard? Well, I might as well help you out...
Honestly, the only retro Nintendo console with a solid amount of JRPGs is the SNES, mainly because it has an amazing amount of 3rd party support. If you need some JRPGs to play, try out Super Mario RPG, Breath of Fire I and II, Earthbound, Terranigma, Secret of Mana and Chrono Trigger.
