Jensen Huang reflects on how SEGA saved Nvidia back in 1995 as the companies celebrate their 30-year partnership anniversary. "At one point, I had to fly to Japan and explain to SEGA's CEO that the technology they contracted us to build would not work. Asked to be released from a contract we could not complete, and then asked that they still pay us ... It was embarrassing and one of the hardest things I have ever done," Jensen Huang said.
