No Hibiki. They didn't hack into it. All precure merchandise from Heartcatch & beyond use the same technique: Code Pressing. I have the Kokoro Perfume+Smile Pact+Cure Module.

Heres the familiar link of the Precure merchandise.

So take the smile pact as an example: See where youre supposed to insert the thingies? Those six things are for each thingy to have a different code to read, so the smile pact will know which sound to make according to the buttons pressed. Watch these videos to understand more about how the Items work:

All you need are some toothpicks

or

some magnets (thin bookmark ones)

There is absolutely no hacking required in this process and all you need is the thing that makes the noise. The only different one is with the cure module, and it is the Fairy Tone that is being the one making the noise, not the module or beltiers, and they only act as the body to press the button on the fairy tones

It took me 15 minutes to figure out what method the Princess Perfume used. MOst of the youtube videos were junk until one. Forgot the link but whatever.
