After I finished recording this video, my New Nintendo 3DS XL was no longer able to read my 17-year old Mario Kart DS cartridge. :(
I may no longer ever be able to play Mario Kart DS from my original cartridge ever again, but at least I was able to get one final memory out of it. (And get to see the credits after!) This race went particularly well, because despite the setbacks, I had a string of good luck near the very end.
Sorry I wasn't able to get source audio. And you know how difficult it is to get source video out of a handheld game system.
