A demo version of Sonic Pocket Adventure for the Neo Geo Pocket Color.the Hedgehog Pocket Adventure for the SNK Neo Geo Pocket Color.

Sonic the Hedgehog Pocket Adventure: Trial (体験版) is an abridged version of the Neo Geo Pocket Color game Sonic Pocket Adventure. It is a playable one-Zone demo that was sent to stores to entice customers into buying the full version. This version barely differs from the final version of the game, with the exception being some Japanese language, and two teaser trailers that are not in the final version.

Before the Sega logo, there is some scrolling Japanese text that translates to "Finally... A supersonic action game... on the Neo Geo Pocket". After the Sega logo, there is a cutscene that introduces the main characters of the game: Sonic, Knuckles, and Tails. Lastly, a silhouette of Dr. Eggman appears, followed by more text promoting the game.

The first dump of the game had problems playing sound during the intro video. On November 6, 2009, a new dump of this ROM was released by NGP PROJECT. This dump appears to fix the sound problems in the opening cutscene. Comparing the two dumps reveals minor corruption in various locations of the earlier ROM.


  • Contains a new intro that's exclusive to this demo, but is otherwise the final game.
