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.
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.
Unused Sound Effects
There are a few sound effects leftover from Puyo Puyo and can be heard in the sound test.
- 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.
