Okay, found it, but there is something odd.
The description says that it added Lyn's announcer, but there is no word about Knuckles'/STAGE CLEAR's announcer.
Also, when I downloaded it, I have put it into a seperate folder and did not insert it into my SD card yet, and I'm glad that I didn't inserted it yet, because the new SAWND file for the announcer voice weights a lot less than the old one.
The old one is 206KB, but the new one is a laughable 25KB, so...what's up with that? Was is supossed to be that small? Especially in comparison to the older version?

Okay, so someone made this:

Where can I download that Announcer fix? Or do I have to redownload PMCC to get that?
