Prerelease Info

Unused Field Maps All unused field maps found in the game, including minimaps.

Unused Battle Maps All unused battle maps found in the game, although some are leftover from PiT.

Unused Items

There's an unused item in the game named "DUMMY". Its design resembles that of the Life Shroom from the Paper Mario series. It restores 60 HP for Bowser when used. If used while Mario & Luigi are fighting an enemy that Bowser inhaled with the Vacuum Block, they will throw it in the air and it will explode, restoring Bowser's HP with its effervescent vapors.

Unused Enemy Behaviors

Please elaborate. Having more detail is always a good thing. Specifically: Bowser can hit flying enemies with his special attacks (specifically Goomba Storm and Magikoopa Mob). Do they work on these flying enemies?

Certain enemies in the game are only meant to be fought with either Mario & Luigi or Bowser, and the other(s) will never encounter it in normal gameplay. However, if hacking is used to encounter the enemies with the other character(s), you can see that their behaviors change:

• Naplock - Its sleeping snot-bubble is avoided just by standing there, but you can be damaged by it if you jump while it's above you. Its block-drop attack is dodgeable with jump; you can break the bricks by jumping. This is very easy to do just by mashing the button.
• Dark Mechawful - Its punching attack is countered by hammering. Its countdown attack is replaced by one that spawns the stars that the head uses when attacking Mario & Luigi on its own, which slowly move toward you and only hurt you sometimes. Its counter is jump. This could be the game glitching rather than something unfinished, possibly the game trying to use the head's star attack with the body attached.
• Choomba - Makes "M" and "L" smoke signals instead of Bowser's fist and shell. It freezes next turn after charging up.
• Dark Trashure - All of the things it throws can be countered with a jump, just like with the regular Trashure, but they are very fast-moving, In fact, it seems that the more damage the object will do, the faster it moves. Not surprisingly, it still throws mushrooms.

When the Mario Bros. are put in a boss battle they usually can't have, the game simply crashes.

The smaller giant battle enemies can also be spawned in normal battle. This may mess up the top screen graphics. Most of them will crash the game, few of them function properly.

Putting small enemies in battle with Bowser will have them run away most of the time.

• Magifoofa - This small enemy can, for some reason, be inhaled. It is the only small enemy with this function. The vacuum block doesn't blink to indicate this.
• Pendril - Unlike the other small enemies, this one will actually try to attack Bowser. It may softlock the game after attacking.

When Bowser is in a battle against an enemy found in his body, he doesn't even attempt to inhale them; after hitting the vacuum block, the game will immediately cut to the enemy's turn. Other than that, they will act the same.

• Goombule - Bowser can't dodge its attack, as it is too short for him to punch.
• Elite Goombule - Same as Goombule. He can hit them with his regular attacks, whereas the Mario Bros. had to use the Green Shell as it was immune to jumping and hammering.
• Spike Blop - Same as Goombule. He can dodge its dropping attack with his shell.
• Calorite - Bowser cannot jump, therefore he can't dodge its rolling attack.
• Air Cannon - The Bullet Bills are too short for Bowser to punch, and he still can't jump.
• Bubble Blooper - Bowser can't hit these enemies with his regular attacks, as they are floating in the air.
• Air Cheep - Same as Bubble Blooper. Its inflating attack can't be countered despite being large enough for Bowser to punch.
• Tenderling - Bowser can counter punch these enemies. Even if he beats them, their attack will still hit as if they are still there.
• Piranaha Plorp - When it creates smog and spits out blobs to hit Bowser, they will always be green, the color that usually indicates they are aimed at Luigi. When they spit out purple blobs, they don't seem to affect Bowser.
• Napse - These enemies are floating, so Bowser can't hit them. Their shots only seem to hit him randomly.
• Stonk - Their surrounding attack doesn't surround Bowser, instead it goes by his sides (where the Mario Bros. would usually be). If the decoy puffs touch him, they just disappear. If the Stonk puff touches him, it takes damage.
• Pep - The speed Pep's attack once again goes to the sides of Bowser and doesn't hit him. The power Pep can be countered with a punch.
• Protobatter - No dodge prompts will show up when battling this enemy.
• Dried Blooper - Same as Protobatter.

Some enemies that can usually only be battled by Mario & Luigi after Bowser inhales them act strangely when Bowser fights them.

• Vacuum Helmet - From the Dark Fawful fight. It is floating, so Bowser's attacks will miss. When Bowser tries to attack it, it glitches and goes higher up on the bottom screen. If Bowser attacks it again, he will walk over to its new location.
• Ice Pack - From Sniffle Thwomp fights. It still acts as if it is on a Sniffle Thwomp. Even though the vacuum block blinks to indicated they can be inhaled, Bowser does not try to, just like the body enemies.

Unlike the Mario Bros., Bowser can have boss battles he normally shouldn't without the game crashing. However, some of their attacks act strangely. Bowser is not able to fight himself, as the game will crash if the fight is set up.

• Dark Star - It is floating, so Bowser cannot hit it. The attack where it creates shadows of the Mario Bros. still uses their damage amount graphic instead of Bowser's. Any attack that indicates which bro it's aiming for will use the color green as if it's aiming at Luigi.
• Chakron - None of Bowser's attacks do any damage. After the battle stops, the game cuts to the file select screen.
• Junker - It will simply defeat itself. The Junker Cans will defeat themselves after they touch Bowser.
• Alpha Kretin - Does nothing at all.
• Bowser Memories - Soft locks the game.
• Dark Star Core - The game will crash unless its individual parts are loaded separately. The graphics for them don't appear, and it does absolutely nothing.

Unused Graphics

To do: Add unused Luigi sprites. And maybe others? Also, add the locations of all these graphics.

Early Bowser Sprite

A single frame of what appears to be an early version of Bowser's battle stance exists, though scaled up and stored with the maps for some reason. It looks like a cross between his final appearance and his Partners in Time appearance, suggesting it was from before the new sprites were finalized.

(Source: Original TCRF research)

Dummy Mushroom

To do: Is this a different file than the unused item graphic?

A graphic for an unused dummy mushroom.

Early Bros. Sprite

An image of Mario & Luigi that was also scaled up and stored with the maps. Its room ID is 0x0224. Seems to be a copy of their appearance from Partners in Time. It's also a bit blurry, unlike the Bowser sprite above.

Water Fountain

Seems to be an early version of the Princess Peach fountain in Toad Town. Interestingly enough, it depicts her as a mermaid.

Unused Bird

Sprites for an unused bird found in the data. Since the sprites are next to Broque Monsieur in the code, it is possible that these birds were intended to be collectible in an early version of the game, as Blitties are in the finished game.

Luigi Carrying Mario Shaped Like a Key

Unused sprites of Luigi carrying Mario shaped like a key, it is unknown what this form of Mario does.

Unused Battle Transitions

Each battle in the game begins with one of four transition animations. However, hacking can be used to play several more animations that are never used in the game:

• ID 1 - The screen morphs into a sphere and drops to the bottom screen, causing a splash effect. This transition appears to be a redone version of the battle transition from Partners in Time, however it is unfinished and causes graphical glitches if it is used.
• ID 4 - The screen rolls into a cylinder and unrolls on the bottom screen. If this transition is called from the bottom screen, the roll appears to suddenly teleport to the top screen halfway through the animation. Not all sprites visible on screen are properly represented on the rolling texture, and the animation frame for those sprites that are represented will not match up once the animation has completed.
• ID 5 - The screen folds into a rectangular prism and unfolds on the bottom screen. If this transition is called from the bottom screen, the prism moves down off screen, and moves up back on screen, unlike transition ID 4. Like ID 4 however, there are the same discrepancies between the sprites on screen and the sprites on the folding texture.

Duplicate Songs

Partners in Time References

In the music data (sound_data.sdat) there are many unused duplicates of songs used in the game.

Their names reference all the music tracks from Mario & Luigi: Partners in Time but, excluding some cases, the name prefix was changed from "MUS_SEQ_" to only "MUS_" and sometimes "_OLD" was added as a suffix.

Present in \BAI\BAI_mon_yo.dat. "Burineko" might be an early name for Blitties, which are called "Blockats" (ブロキャット) in the final Japanese game.

Bowser's been blown from Peach's Castle to Dimble Wood. What will he do?

Unused save text that appears on the file select screen while saving while Bowser is in Dimble Wood before talking with Fawful. This cannot be seen in-game, as there are no accessible save blocks without the use of cheats.

Debug Room

Like its predecessor, this game has a debug room based off the generic inside-Bowser battle background. Select a number, and Mario & Luigi will be sent to some places and cutscenes in the game. The Japanese version has description text, unlike the US version, which replaces them all with "no need to translate". Interestingly, in the Korean version the original text was added back, and uses the English alphabet and English words on occasion.

• 41 - Fourth room in the Airway.
• 42 - Fifth room in the Airway.

• 10 - Second selection from 0-10 corresponds to each part of the game, and therefore blocks access to some of the areas in Bowser's body. 0 is the start of the game with only the Trash Pit, Funny Bone, Toad Square, and Challenge Node, and 10 is the end of the game where all areas are accessible.
• 11 - Related to 10, prevents access to everything except Trash Pit, Arm Center, Funny Bone, Toad Square, and Challenge Node.

• 32 - Shake effect.
• 33 - Same as 23.

Extended Debug Room

If further hacking is used to move away from the blocks, the "Debug Room" is found to be much larger than expected, with the debug functions to the far left of the room. The upper platforms are not solid, but the lower platforms are. The floor of the room also seems to have a special texture not seen anywhere else.

Regional Differences

To do: A The European version contains a glitch that corrupts the grafics in the Bowser X fight, find out why it happens. The glitch might also randomly happen during the Shroob fight.

Japan	US/Europe	Korea

The hand cursor is closer to the text in the Japanese version. The text font is slightly different in the Korean version. The Korean version's copyright date was altered to add 2011, as that's when this game came out in Korea.

File Select Screen

Japan	US/Europe	Korea

In the US, European and Korean version, the L and R buttons look closer to their real life counterparts. When no save files are present, "NEW FILE" is shown in the US, European and Korean version (the latter having slightly bigger text), while "NO DATA" is shown in the Japanese version. The position of the text is also slightly different between versions.

Menu Tabs

Japan	US/Europe

The menus were tabbed in the Japanese version, while in the US and European version, the tabs are moved upward, and those not being used are darkened.

Anti-Piracy

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Find and document the code that causes this behavior. Same with the anti-cheat.

If the game detects it's a copy, it will force the game to have lots of issues unless the ROM is patched or a compatible flashcart is used to play it. Issues can also occur when running the game on older versions of DeSmuME if proper settings are not used. Issues include random freezing, forced black screens, forced softlocks, battles freezing (JP), no saving (?), save screen softlocks (USA) and possibly more.

Anti-Cheat?

To do: Research this one more. These can be things like not being able to hit the Attack Piece Block in the Blue Shell tutorial, not being able to move the underwater spike balls in Pump Works, or the game simply hanging or crashing.

Certain cheats used can be detected by the game (?) to mess up playthroughs on certain flashcards.
