[NSFW] "I've come to make an announcement!" This replaces the audio from the cutscene where Eggman blows up the moon with the real-time fandub version from SnapCube. Both the English and Japanese audio have been replaced. You can view this cutscene from Story Select ("World Domination" for hero and "The Eggman Empire" for dark).
Mind if I ask how you achieved this? I remember trying to get something like this to work a few months back in this request thread, and I had to declare it a failure as I didn't know what the video was doing for audio. Doesn't help that the Hacking Guide I've relied on for years is severely out of date in many places, as I state here.
