Great, and here's a walkthrough

Mecha shouldn't be a problem. With Eggman your first must be PROTECT, then when MEC(Master Emerald Cannon) isn't open use ATTACK and wehen it opens (sorry for my english) First use your SP ONLY when it is open (when closed after the beam go back to ATTACK)when you don't have any SP anymore and it opens up use PURPLE VORTEX and when your health is under 2000 use HEALER, that's how I have beaten Eggie and retrieved the Master Emerald. By the way, the password actually is Nightmare, but i don't know how it could be that in isn't working(once again sorry for my English but i'm from The Netherlands(or Holland however you guys call it)) so when want to skip the battle go to the scene select and the password for the last scene is "Reala"

Tails ownz :)

OMG tails i love him! i cant get past the big robot thing!!! >:( oh well its tails!! <333
GO TAILS!

Pretty much..

Nice "movie" and you included fights alot more often then many other movies of this type. Anyways for all those who have a hard time fighting the boss, try this:
When Eggman's giant robot is in normal state, just shoot him with normal attacks.
When he prepares to launch his super beam, shoot him with TRIPLE SHOT (it does more damage/Sp used then the beam, so in a long fight like this it does make a difference). When you dry up on your Sp use as little MP as possible as you'll need the Healer quite a bit. That should do the trick...well it did for me, at least.

Hmmm..............

the game it AWESOOOOOME but why tails uses Mecha instead it owen skills?!?

password wont work...

the nightmare password dosnt work for some resion.
otherwise,besides eggman,its perfect. 10!
