Prop Feature Migration: DIY?

Props

In the saber sense prop:

#define SABERSENSE_BUTTON_CLICKER
  Button Clicker to play press/release wav files when
  buttons are pressed. Intended for Scavenger hilt
  where wheel makes tactile feel difficult.
  Requires press.wav and release.wav files to work.

I first saw it here in the OS8 beta thread:

Not sure where to begin and end, but in prop I see:

bool Event2(enum BUTTON button, EVENT event, uint32_t modifiers) override {
  if (GetWavPlayerPlaying(&SFX_boot)) return false;
  switch (EVENTID(button, event, modifiers)) {
    case EVENTID(BUTTON_POWER, EVENT_PRESSED, MODE_ANY_BUTTON | MODE_ON):
    case EVENTID(BUTTON_POWER, EVENT_PRESSED, MODE_ANY_BUTTON | MODE_OFF):
    case EVENTID(BUTTON_AUX, EVENT_PRESSED, MODE_ANY_BUTTON | MODE_ON):
    case EVENTID(BUTTON_AUX, EVENT_PRESSED, MODE_ANY_BUTTON | MODE_OFF):
      SaberBase::RequestMotion();
#ifdef SABERSENSE_BUTTON_CLICKER
      // Intended to play click sound on button presses, primarily for Scavenger 
      // hilt where wheel makes tactile switch feel difficult.
      PlaySound("press.wav");  // Requires press.wav file to work.
#endif
      return false;
    case EVENTID(BUTTON_POWER, EVENT_RELEASED, MODE_ANY_BUTTON | MODE_ON):
    case EVENTID(BUTTON_POWER, EVENT_RELEASED, MODE_ANY_BUTTON | MODE_OFF):
    case EVENTID(BUTTON_AUX, EVENT_RELEASED, MODE_ANY_BUTTON | MODE_ON):
    case EVENTID(BUTTON_AUX, EVENT_RELEASED, MODE_ANY_BUTTON | MODE_OFF):
#ifdef SABERSENSE_BUTTON_CLICKER
      PlaySound("release.wav");  // Requires release.wav file to work.
#endif
      if (SaberBase::Lockup()) {
        SaberBase::DoEndLockup();
        SaberBase::SetLockup(SaberBase::LOCKUP_NONE);
        return true;
      } else {
        return false;
      }

That would be most excellent of you if possible.
