Here's a hack that "converts" Ms. Pac-Man to Pac-Man for the NES. This changes all the graphics, colors, and levels to the ones from Pac-Man.
Everything from Pac-Man was put into Ms. Pac-Man. Some differences you may see like the bouncing fruits and also there are also new cutscenes for the hack.
Database match: Ms. Pac-Man (USA) (Namco)
