Who here has beaten the final boss?

(And I mean FINAL final boss, not Egg Emperor, the one you unlock by beating Egg Emperor as all four teams and collecting the Chaos Emeralds)

Everyone on here who's beaten him, speak up. If there are bragging rights for anything, it's this, because I have searched every single Sonic website, every single forum, every single Gamefaqs, every single walkthrough or walkthrough video and I haven't found a single way to get that third Chaos Emerald (the yellow one, at the end of BINGO highway) that works. I've seen videos of people with cheat codes getting to him, though, and he looks pretty easy too, and Egg Emperor isn't even a challenge to me anymore... but that third Chaos Emerald, there's a 1% chance of getting it.

So... anyone who's beaten him, you've beaten the hardest thing in video game history that hasn't been reviewed by AVGN

I didn't reach to the finel boss
because i didn't collect all the emeralds
do you have any advice for me ?

"Metal Sonic" was no easy cakewalk in the park, he is tougher than he looks. and this is coming from someone who isn't a Sonic rookie.
