Dr. Robotnik's Mean Bean Machine/Hidden content
From Sonic Retro
Unused Stages
The Lesson stages from Puyo Puyo were not cut from the game and can be cut by using PAR code 00BEFE:000? (? can be changed to 0-2).The tutorial text is glitchy and no music plays. Coconuts stands in stragne positions in the stage cutscenes. Defeating the third Lesson stage advances the player to the ending cutscene.[1]
Sound Test
If playing the game on a Japanese Mega Drive via patch code a sound test will be available in the Options screen. The Game Genie code ADTT-AAAE will also make it appear.[2]
Unused Sound Effects
There are a few sound effects leftover from Puyo Puyo and can be heard in the sound test.[3]
- 0C - Stage Clear jingle
- 0F - "Brave". A remix of this is used in-game but this is the original arrangement.
- 10 - Theme of Puyo Puyo. A remix of this plays over the credits, but this is the original arrangement.
- 14 - Unknown. Perhaps a alternate warning music for the final stage.
Checksum Error
Puyo Puyo's checksum Error still exists in the game, and is triggered the same way.[4]
