Sonic 1: Special Version  -  Build v. 3.0.

Ohh yeah. Here is where starts the good stuff!
I'll explain: This was the first public release of the game, and I was like:
"I hope the people likes what I did".   ...
Well... everything was a failure.

Everyone started saying that the ability "Chrono Attack" was stolen.
I was very confused at first, but then, after 2 million post destroying me, someone said:
"Code used on "Sonic The Hedgehog: Open Source Project" is stolen from other hacks."

Well, I fixed that issue on the "v. 4.0." build. But, do not forget that this is still "v. 3.0.".
So...  ...enjoy?
