In this ROM hack, it has been 5 years since Super Mario 64, Peach has given up being the monarch of the mushroom kingdom and is in the process of moving into a new castle however bowser already ...

Driving through the window causes a Mario 64 painting-style ripple, and warps you through to a mirrored version of Mario Kart World's, er, world. Ta-da! Even your world map is flipped.
