Now that the activation code has finally reached my e-mail, address, I can settle the David Hayter business. Hehe, I'm not sure why Hayter is credited in the end, but to answer all your questions folks, I was the guy who voiced for Solid Snake. "TheBigK."
I didn't use any voice edits, or rip any voice bits from videos, it was all directly from the horses mouth, and that horse would be me...hehe. Truth be told, I'm best known for my voice as Solid Snake in the CPO series, and in various other places. I am able to inflict my speech so that I can mimic the way Hayter pronounces words and letters, and can basically pull off the Snake voice like a charm. Only problem is, I use a laptop and a crappy mic, so the quality of my voice has to make up for the God awful static you hear in the back, like in these two vids:

Glad y'all liked it, I was certainly glad to get the part, and God I loved the Olimar bit. "Captain Fal-Olimar." Haha, great stuff.
Honestly, Episode 9 was great, and I can't wait to see episode 10.
