No doubt the NES. It also had the first Earthbound game.
Although, with Nintendo, they have redefined their IPs multiple times. So it’s a little bit of an unfair advantage; apart from not being the entire truth.
Mario Kart is a spin-off of Mario and shouldn’t be counted. Otherwise DKC should count as an original IP on SNES.
