NEC-Hudson 32-Bit Prototype System circa 1992

Found an EGM article on Nintendo SNES DSPs including the ones that are in Pilotwings and Mario Kart.

While on the cartridge upgrade chips, why didn't SNK use them? The main downside of the chips is the cost. But with Neo carts costing hundreds each, that really wasn't an issue. Near the end of the Neo's life, I bet a chip that would shame the SuperFX would probably add $1 to the cost, and you could get something truly decent for $50-100. For a company intent on keeping a system alive, you'd think they'd have gone that route.
