Since this is an all-time list, if you want to include this my records indicate that I beat Mr. Nutz for SNES legitimately on April 6, 2014.
I also beat the Mega Drive version legitimately on March 12, 2014.
That year I started out by playing one console each month. January was NES, February was Sega Master System, March was Sega Genesis, April was Super Nintendo, May was Sega Saturn, June was Playstation and July was Nintendo 64, which was cut short due to my desire to finish the games I cut off for the previous systems just because the month changed.
