Hello all! I'm MrL314, a Super Mario Kart hacking expert. I do a lot of projects involving Super Mario Kart reverse engineering and hacking, as well as creating many tools for the community to use in their efforts. My work has been featured by VGC, Kotaku, NME, NintendoLife, ScreenRant, and Supper Mario Broth, and I have aided in providing information for multiple videos and projects! (see Accreditations)
