Sonic Pocket Adventure - Unused Intro Sequence!
The unused intro sequence.
The Japanese demo version of the game titled Sonic the Hedgehog Pocket Adventure: Trial was shown in stores to promote the game. It features a single Act of Neo South Island Zone. The demo version has extra content at the start which was never featured in the final game: Before the Sega logo screen, some Japanese text is shown that translates into "Finally... A supersonic action game... on the Neo Geo Pocket". An intro sequence is then shown, featuring Sonic, Tails, Knuckles, and a dark silhouette of Dr. Robotnik, along with more text promoting the game at the end.
