So the description of this achievement is kinda confusing, so allow me to elaborate: within a single stage, you need to eat both fruit that spawn as well as eat all four ghosts with each of the four power pellets.
It is important to note that the ghosts' movements are 100% determined by Pac-Man's position and direction. This means that if you do the exact same movements (note:
movements not
button inputs), you will get the same result every time.
Obviously this is easiest on the first stage. There are many youtube videos of a "perfect cherry" completion for stage 1 (i.e. max score possible), and mimicking
exactly what they do will net you the achievement.
I link below my completion, which is based off of a popular route on YouTube for the original arcade game (I did not come up with this pattern myself, but I wanted to verify that it works in this version of the game). It may take some practice, but if you learn the pattern and execute it correctly, you will get the achievement and a perfect score too
