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.

Debug Mode[]

Changing byte 0x1F of the rom to 0xFF in a hex editor will enable Developer Mode, and by pressing the Option button while the Sega screen is displayed, the main debug menu will open. Pressing the Sega Genesis B Button button in-game allows the player to switch between Sonic and Tails. The pause banner is disabled entirely in debug mode, and a free-movement mode is possible by pressing both Sega Genesis A Button and Sega Genesis B Button simultaneously.

There are six options on the main debug menu:

  • Beginning: Level select.
  • Go To Room: Goes to the normal Room Select menu.
  • Direction: Plays the ending cinematics.
  • Sound Test: Opens a sound test, different than the in-game version.
  • Debug Option: Options to toggles various in-game options, such as hitboxes and coordinates.
