The preview of Sonic the Hedgehog Pocket Adventure was sent to the press to generate publicity. It was found and released by drx on January of 2017. It's dated October 22, 1999, 1 month and 8 days before the final release. This preview has a lot of differences from the final game. The label says ロックマン (Rockman) suggesting there was some kind of Megaman game on this cartridge.
