Evidence of this includes function names and script files containing debug content with mentions of the Wii Remote, DRC, functions that aren't accessible or are stubbed, some function names for some features of this build in the Wii U Kiosk Demo map, a debug text display feature that was shown in the Mario Kart 8 Direct, and more. Comparing the debug folders, function names, and some script files of this prototype to the debug folders of the Kiosk Demo of Mario Kart 8 for the Wii U, it is likely that some of the debug features came from the original Mario Kart 8, but with more features added.
