Hahaha, calling him noob. Guess what it doesn't work that easily anymore. You cant just overwrite a file anymore. Its incredibly annoying. I dont know why they did all this code changing.
First of all, you can't make a charging sound for Vegeta's FF, simply because he doesnt have one. You can only change the sounds their already are. They added a big bang charge sound in this release which is good.
This is what you've got to do if you want to change sounds. First, create a new sound. Second, open the old sound. Paste the new sound over the old. Hit save. Grant it, its sitll pretty easy, but the old way was much easier. As long as you had the correct ESF format you could replace sounds, now you have to "edit" the old sound so to speak.
This absolutely sucks for a number of reasons, 1 being I can't release new soundpacks, because you can;t replace anymore as I said before, you have to edit the sound by pasting over it. So no more soundpacks from me or anyone cuz I dont know why the hell they did it but you can't overwrite.
EDIT: Oh yea, Vegeta's renzeko sound file doesn;t work, for the reason I'm assuming. They probably replaced sounds sometime during release candidates and when they saw that the overwrite wasn;t working thye just deleted the old and no sound showed up at all.
