Dr. Robotnik's Mean Bean Machine (Genesis)

This game has a notes page
This game has a prototype article
Dr. Robotnik's Mean Bean Machine is a Westernized Puyo Puyo based on the syndicated cartoon Adventures of Sonic the Hedgehog.
Most of these are leftovers from Puyo Puyo
Perhaps unsurprisingly, the game still contains unused assets from the arcade Puyo Puyo. The game no longer contains the "Insert Coin" prompt that was buried in the Mega Drive Puyo Puyo's title screen data, but still contains the credit(s) counter in its gameplay sprite data.
8x16 text is used rather than a unique graphic for the PAUSE text. This is the one used in Puyo Puyo.
Graphics used in Puyo Puyo to denote the 1P VS 2P difficulty modes.
While the game only uses numbers from 1 to 5 to mark the difficulty levels, other numbers do exist.
The entire Endless/Lesson Mode tileset is still present in the game, but is never used. As this game uses only one graphic pointer for the entirety of Scenario Mode (unlike Puyo Puyo), the leftover Lesson Stages do not actually load this tileset. Note that the palette which should be used for these tiles either has been removed or it's never loaded, so the one from Puyo Puyo is used in the image.
This shadowed block was part of the background in the Endless Mode from Puyo Puyo. While a similar set of tiles is still used as the background of various screens, this one is not.
The flashing square is only used in the first Lesson stage.
This is the tutorial text shown in the first Lesson Stage in Puyo Puyo. Since this is only present in the Endless Mode tileset (which is never loaded during gameplay), the actual object appears scrambled when the stage is accessed in the game.
Graphics of Arle! They are always loaded initially (and then partially overwritten) during cutscenes due to developer laziness as they contain the dialog box sprites.
Sprites of Harpy exist too for whatever reason; these are probably the forgotten duplicate Harpy sprite data from Puyo Puyo, as these are never even loaded by Mean Bean Machine either.
Leftovers from the Game Over screen of Puyo Puyo. Unsurprisingly, they are never loaded in memory too.
More leftovers from Game Over screens, this time from the 1P VS 2P Mode.
The graphics from High Score screen used in Puyo Puyo were replaced during the conversion, but not completely as they still get loaded in memory.
The High Score screen only uses letters.
This was used to mark the different game modes. Appropriate graphics exist and are used in this game.
The original font of Puyo Puyo is only used in the Checksum Error Screen, so most of it is unused, including numbers and their duplicates.
Another leftover from Puyo Puyo. The font used in the demo mode of the original game obviously isn't used here.
While this 8x16 font is used during the cast roll in Puyo Puyo, this game uses a different 8x8 one. This is another of the few graphics to never get loaded.
The Lesson Stages of Puyo Puyo are still present, and can be accessed via patch code 00BEFE:00?? (where "??" is 00, 01, or 02), although they're a bit glitchy: the tutorial text is scrambled, no music plays, Coconuts stands at odd positions in the stage intros, and Scratch takes the place of Skeleton-T as the challenger. The flashing squares showing which beans can be cleared with the current piece still remain, though. Beating the third Lesson Stage advances the player to the ending scene.
Find code for Sonic Classics version.
Normally, the game will stop you from playing if it is played on a Japanese Mega Drive. However, if you bypass this (for instance, by changing the region while running or using some sort of patch code), you will be rewarded with the ability to access the sound test in the Options screen. Game Genie code ADTT-AAAE will also make it appear, but it will trigger the Checksum Error below if it is enabled before the Sega logo screen.
In the Sonic Classics version, the above region-change trick does not work.
Some of the songs in the sound test (specifically, 01, 0C, 0D, 0F, 10, 14, and 15) are hidden if the console region is set back to US. However, if the console region is still set to Japan, these tracks will get shown after the normally accessible tracks.
Present in the Sound Test are a few unused songs. These are mostly leftover tracks from Puyo Puyo, which have been updated to use different instruments and actual drum samples, versus the noise-based percussion used in the original game.
|01||Parts of the track sound similar to 02 (used in the intro) and 07 (the song used for Stages 9–12).|
|0C||Stage Clear jingle from Puyo Puyo.|
|0F||Brave of Puyopuyo. While a remixed version is used in-game, this version uses the original arrangement.|
|10||Theme of Puyopuyo. While a remixed version plays over the cast roll, this version uses the original arrangement.|
|14||A faster and slightly altered version of the Stage 13 theme.|
|15||A very weird sound, strangely in the BGM menu.|
The checksum error screen from the Genesis Puyo Puyo still exists in this game, and is still triggered in the same way, which is of course the ROM checksum failing.
The game contains tilemaps from the 1P VS 2P and Endless Mode used in Puyo Puyo.
The tilemap is split in many parts. Find all of these.
Note that while the tileset for Endless Mode still exists, the 1P VS 2P one doesn't.
Sixth Puyo Color
Color ID: 02
Like in Puyo Puyo, code for the sixth colored puyo still exists here and its palette is used properly. As the graphics were overwritten, in the fixed screenshot tiles from the violet puyo are used.
The Korean version changed the lockout screen message to all-caps, and corrected the "onry" typo to "only". It also has the Sound Test accessible without needing to change the region.
