I've beaten it, but yes a bug is present, just not there. The bug I am speaking of is in the Dark Story's credits, it will tell you what you got for beating the Dark Story, then lock up. Let the DC cool for a day or four, come back, try to find those features, not there. You have to play the final Dark stage again and sit through the credits, just to see it lock up again. I've almost become a pro at beating Sonic with Shadow in that final stage.

Anyway, I am babbling, I think your stuck at the stage where Tails/Eggman have to get to the cannon's core, and your both in MECHs. The trick for tails is NOT to get gun happy, you will usually end up blowing up bridges and critical areas most of the time unreachable if you blow it up. Not sure about Eggman though... but neither of those are the FINAL stages for Hero/Dark.
