This is an incredible achievement, the only negative i can see is in the F-Zero example there is a clash between the low rez horizon graphics that don't use mode7 compared to the rest of the track. It's a little jarring. Pilotwings and Mario Kart look amazing. If Nintendo have any sense they will hire the people who made this happen and get them to make a Nintendo Switch version of that emulator so they can pimp "enhanced" versions of SNES games for their online service. (spoiler alert: There is no chance in hell of them ever doing this sadly)
