Paper Mario: The Thousand-Year Door is a Nintendo Switch remake of the 2004 Nintendo GameCube game of the same name released worldwide on May 23, 2024. First announced during the September 2023 Nintendo Direct, it is the first remake in the Paper Mario series.

The title features visually enhanced and updated graphics along with new gameplay features. However, it remains faithful to the style of the original game: the characters maintain their designs from the original release (for example, Princess Peach keeps her pre-Mario Party 4 dress design), rather than the updated designs used in the following Paper Mario games. Many voice clips from the original game are also reused, despite voice actor changes since the original game's release, including Charles Martinet, Jen Taylor, and Scott Burns, former voice actors of Mario, Peach, and Bowser respectively.

List of changes

New content

General

• Like in Paper Mario: Color Splash and Paper Mario: The Origami King, a concept art gallery, the Art Gallery, is available. It can be viewed from the menu, with more pieces unlocking throughout the game. The gallery includes concept art from the original game and specific to the remake. Art galleries are sorted by the story's chapters' locations and are unlocked after collecting every Star Piece from that chapter's locations and taking the chapter's Crystal Star to the Thousand-Year Door.
• An in-game music player, the Sound Gallery, is added to the menu. Music tracks are sorted by the story's chapters' locations in which they play and are unlocked after collecting every Shine Sprite for that chapter and taking the chapter's Crystal Star to the Thousand-Year Door.
  • Equipping the Nostalgic Tunes badge allows the player to listen to the GameCube versions of the tracks in the Sound Gallery as they are unlocked. While the badge is equipped, tracks exclusive to the remake are disabled.
• A Notes tab has been added to the menu. This lists active Trouble Center requests and any of Merluvlee's predictions that are still relevant.
• A few new emails have been added, such as one from Professor Frankly informing Mario about the First Attack badge or one from the Toad Bros. Bazaar informing Mario when the Contact Lens have been restocked.
• A list of controls for the player's current controller can be found in the menu.
• A newly-arranged soundtrack, new music tracks, and extra sound effects were added.

Characters

• A Purple Toad called the Battle Master can be found around the world. When talked to, he allows Mario to practice his attacks, in a similar fashion to the Action Command Dojo and Battle Lab from previous games. During his battles, Mario fights cardboard Goombas called Goomboards.
• A Little Mouser named Ian Foomus appears in the Trouble Center, offering advice to help with different Troubles.
• A Orange Toad called the Toad salesman appears at the end of Pirate's Grotto, selling items to the player.

Glitz Pit

• There is an Exhibition Match option and an option to read the rules when reserving a match.
  • Exhibition Matches allow Mario to select and fight any Glitz Pit team that he is currently ranked above (whenever or not he has fought them previously), and these battles do not have any battle conditions, nor do they affect Mario's ranking.
  • As a result, the player can easily obtain Tattle entries for enemies exclusive to the Glitz Pit if they failed to do so earlier.
  • Wings of Night and The Destructors can only be fought through Exhibition Matches.
  • After Mario's rank is reset after clearing Chapter 3, he must rank up to access Exhibition Matches again. However, Prince Mush can be fought regardless of rank.

New bosses

• Two new bosses have been added:
  • Prince Mush can be challenged at the Glitz Pit. To unlock him, the player must complete Jolene's Trouble, "Help wanted!", and then wait some time to receive an email from her talking about new Exhibition Matches and that Mush is training. After waiting some more time, the player will receive another email, this time from Prince Mush himself, issuing a challenge. By heading back to the Glitz Pit and selecting Exhibition Match in any league, the player can challenge him to a fight. Mario will receive Prince Mush's Belt if he defeats him.
  • Whacka can be found in the Pit of 100 Trials and can be defeated to receive the Gold Whacka Bump. For him to appear, the player needs to have completed the entire Pit of 100 Trials by defeating Bonetail at floor 100 and hit Whacka in Keelhaul Key enough times to make him stop spawning there (he will exclaim "Whack-a-woooooooooooo..." when he disappears for the last time). After waiting around 30 minutes of in-game time, the player must return to Rogueport to receive an email called "RDM Extra Issue," which says a mystical creature has been seen deep in the pit. Whacka will appear at floor 100 after this email, and whacking him there will trigger his boss fight. Returning to the Pit and fighting Whacka subsequent times yields a regular Whacka Bump, meaning the item can now be obtained infinitely, unlike the limited amount in the original.

Recipes

• The Hottest Dog recipe has been added and can be made by mixing a Hot Dog with Hot Sauce. This is in reference to the Businessman's Trouble. In the original Japanese text, he discussed combining his Hot Sauce with Mr. Hoggle's Hot Dogs, but this resulted in a Mistake if attempted in the original game. In the original English localization, he referred to combining a "Fat Dog" (a nonexistent item) with Hot Sauce to create a "Tongue-Blistering Fat Dog", which the remake respectively changes to "Hot Dog" and "Hottest Dog" to allude to the new recipe.

Pit of 100 Trials

• Upon completion of the Pit of 100 Trials at least once, a Mover outside the entrance provides fast travel to the 50th floor for 300 coins.

Tattles

• There are ten more Tattle Log entries compared to the original game, bringing the total to 134. Amongst these include the Goomboard, the Fuzzy Horde in Shhwonk Fortress, the X-Naut horde in Lord Crump's second fight, and the two new bosses, Whacka and Prince Mush.
  • The second fights against Bowser, Doopliss, Beldam, and Marilyn and the second phase of the Shadow Queen now have separate Tattle Log entries. As a result, if they were Tattled in their first battles, their HP is not immediately shown in their rematches until they are Tattled again.

Creepy Steeple

• The Creepy Steeple Boo can be found in the storeroom after freeing the Boos trapped in the box under Creepy Steeple, where he will quiz Mario on various parts of the story. There are six quizzes, with the last quiz having 15 questions in total and only being available during the post-game.

Trophies

• Three trophy items have been added as rewards for Journal completion:
  • The Cooking Trophy for obtaining all recipes
  • The Badge Trophy for obtaining all badges.
  • The Tattle Trophy for completing the Tattle Log.

Badges

• The Nostalgic Tunes badge, resembling a Nintendo GameCube, can be bought from the Lovely Howz of Badges for one coin. Equipping it will revert the music to the original soundtrack. The game still plays tracks exclusive to the remake, however.
• Mario is awarded with a Gold Medal for obtaining all three trophies. It has the effect of visually turning him gold, and the effect will stack with the L Emblem and W Emblem.

Gameplay changes

Menus and controls

• The player's play time for their save file can no longer be seen in the game's pause menu.
• The player now uses and instead of and to scroll through their list of items and badges.
• As with entries since Paper Mario: Sticker Star, dialogue can no longer be sped up if it is the save file's first time viewing the dialogue, nor can the player view previous messages in the conversation.
• The Mailbox SP mail system has been reworked to function similarly to the notifications system from Paper Mario: The Origami King, where alerts no longer affect the player's ability to navigate in-game. Pressing while the notification is on-screen immediately opens the email.
• Like Paper Mario: The Origami King, the last saved point can be accessed from the Game Over screen and the current scene can also be played again, with any scene in which the player was last in capable of being played again. In some instances this option to play from the last scene loads a save from before the last Save Block was hit. In the original, this was limited to certain situations.
• Like with collectibles in Paper Mario: The Origami King, the map screen tracks the percentage of collected Star Pieces and Shine Sprites from each location.
• When leveling up, the player has to press a direction with the to select an option rather than HP being the default.
• Like the first Paper Mario, if the player is wearing an FP Plus or HP Plus, increasing their FP or HP respectively, when leveling up, the higher numbers for increasing FP or HP will take into account the badges worn.
• All partners are fully healed upon leveling up rather than only the active one.
• The Nintendo Switch system keyboard is used when prompted to name the Yoshi Kid instead of an in-game one. However, all other text input prompts, such as the ones for inputting Doopliss' name and the access code in X-Naut Fortress, still use an in-game keyboard.

Field

• Mario can swing his Hammer forwards and backwards like in entries since Paper Mario: Sticker Star. In the original game, he could only swing his Hammer sideways.
• Bushes can no longer be interacted with when near them, but they can be crumpled with the Hammer for the same effect, as with Paper Mario: Color Splash. Incidentally, Bowser can still interact with bushes in the same manner as in the original game.
• Both Mario's partners and NPCs will react when hit with Mario's Hammer. NPCs will also react when Bowser breathes fire on them during his intermissions.
• Like in later entries, there is safeguarding on the edges of areas to prevent the player from accidentally falling off. If Mario approaches an edge, he will stop moving forward and teeter on the edge to give the player the ability to move back onto stable ground, only falling off if the player continues to move forward after the animation begins.
• and have new functions. Pressing now opens up the Partner Ring, which Mario can use to switch between partners, while makes a partner provide Partner Hints (whether or not they are active) to direct the player to their objective. The partner that gives the player the hint is usually Goombella, but it may vary depending on the situation or the area. In the original game, was only used to navigate menus.
• The Paper Plane mode stays at a fixed distance from the ground until it has transcended the horizontal width of the activation panel.
• The player can use the Hammer to locate flippable panels on the ground containing Star Pieces, although the Hammer still cannot flip them. In the original game, this is not possible with any Hammer, with the only way to locate panels being to use Spin Jumps.
• When using Koops's partner field ability, a green circle marker with an arrow appears where Mario launched Koops, with the arrow indicating the direction Koops's shell will launch.
• Breaking large blocks using the Super Hammer or the Ultra Hammer requires Mario to charge beyond the minimal amount.
• When riding on the Yoshi Kid, Mario has momentum-based physics that apply when riding off edges, making traveling down them slower than in the original game. The Yoshi Kid's flutter jump is also more continuative from walking and thus slightly different from the original.
• The player can open doors and talk to NPCs while riding on the Yoshi Kid, although Mario still dismounts off the Yoshi Kid to do either action.
• If Mario is riding the Yoshi Kid as he falls on a jump pad, he will stay on the Yoshi Kid after bouncing off, unlike in the original game.
• There is a prompt to check interactable elements in the scenery, to talk to characters, or to have Goombella Field Tattle a character, hinting at what the player can do with them.
• Enemies on the field have a shorter range of sight to spot and chase after Mario than in the original game.

Warp Pipes

• As with entries since Paper Mario: Sticker Star, Warp Pipes are entered by pressing , with a prompt appearing above one to tell the player to do so. In the original game, entering Warp Pipes required tilting down on the and the only hint was dialogue from Professor Frankly when he instructed the player on how to enter the pipe at the beginning of the game.
• They have new hitboxes.
• When emerging from one, Mario automatically jumps out and forward.
• There is a new Warp Pipe room, similar to the "One World, One Pipe" room in Musée Champignon from Paper Mario: The Origami King, replacing the original pair of Warp Pipe rooms across Rogueport Underground. When entering this room after taking a Crystal Star to the Thousand-Year Door, the Magical Map is held up in a similar fashion, unlocking a pipe leading to a locale for that Crystal Star's chapter. There are seven pipe slots instead of four, with a pipe leading from this room to Rogueport Plaza also able to be opened. The door leading to the room on the right side is also now hidden and requires Flurrie to reveal it.
  • Pipes 1, 2, and 6 lead to the second area of Petalburg, the outside of The Great Tree, and the fountain in Poshley Heights in the same spots as in the original game.
  • Pipe 3 leads to Glitzville, southeast of the juice shop.
  • Pipe 4 leads to the second area of Twilight Town.
  • Pipe 5 leads to the campsite of Keelhaul Key, instead of the jungle like in the original game.
  • Pipe 7 leads to the second area of Fahr Outpost.
• Several new ones were added:
  • One was added behind the Last Stand P badge in Hooktail Castle that takes the player back up without having to backtrack.
  • One was added from Creepy Steeple's basement to the right-most house of Twilight Town to cut backtracking in Chapter 4. It can be unlocked by heading right from the room with the parrot.
  • One was added in the Palace of Shadow leading from the Depths room before the Shadow Queen south of the save block back to the entrance of the palace at the bottom middle of the entrance room to cut backtracking. It appears after dying to the boss or clearing the game. If it does not appear, the player must restart the game and load the save. Mario's active partner will comment on the new pipe's appearance in the room.

Save and recovery blocks

• Like Paper Mario: Color Splash onward, when the player hits a Save Block, the game does not ask whether to save or not.
  • This also applies when the game transitions to each character segment and when the game is completed.
• New Save Blocks have been added or relocated:
  • The one near the pedestal of The Thousand-Year Door is moved to the entrance of the Pit of 100 Trials.
  • The one in the first area of Boggly Woods is moved to the second area, allowing the player to save before the Three Shadows fight.
  • One appears in the third area of Twilight Trail, past the fallen tree.
  • The Save Block in Creepy Steeple's main room has been moved to the room with the spiral stairway.
  • One appears outside the derelict ship that houses a Black Chest in Pirate's Grotto.
  • The one that appeared in the conductor's room in the Excess Express is moved to the blue area (housing rooms 6, 7, and 8).
  • One appears on Sublevel Two of the X-Naut Fortress, just east of the elevator doorway.
  • One appears in the Palace of Shadow in the round room, replacing the ? Block left of the Badge Block that originally contained only one coin.
• New recovery blocks have also been added:
  • One appears in the third floor of Hooktail Castle and costs 10 coins to use.
  • One appears at the entrance to the Pit of 100 Trials, next to the new Save Block.
  • One appears in a tall chamber in the Pirate's Grotto next to the Save Block.
  • One appears in the outdoor section of Riverside Station.
  • One appears at the easternmost part the Fire Bar section of the Palace of Shadow, costing 20 coins to use.
• The Save Block and recovery block in the Palace of Shadow's courtyard have switched spots, with the recovery block now on the west side of the canal and the Save Block now to the east of the canal.
• The cost to use the recovery block in the factory of X-Naut Fortress has increased from 10 coins to 20, matching the cost of the one at the front entrance.

Trouble Center

• The Newsletter... Trouble is only available after clearing Chapter 7 instead of after Chapter 4.
• For the Important thing! Trouble, Frankie's Wedding Ring is on top of the wall beside Professor Frankly's house (where it is in the Japanese GameCube version) instead of on the ground near Garf's house.
• The amount of coins rewarded for several Troubles have been changed:
  • All Troubles that originally rewarded Mario with twenty coins (Need a key!, Safe delivery..., Competitor research!, Find this guy!, I can't speak!, and Roust these cads!) reward him with thirty coins instead.
  • After completing the Life Mushroom! Trouble, the Puni elder rewards Mario with fifty coins instead of sixty coins.

Recipes

• All versions of the game use the same list of recipes as the international version. However, it is possible to make Trial Stew by mixing Thunder Bolt and Thunder Rage, a recipe originally exclusive to the Japanese version.

Skippable cutscenes

• Cutscenes that have already played out before can be skipped with . These scenes include:
  • The storybook intro sequence after saving at least once (any button, barring and can be used to skip it).
  • Zess T.'s cooking sequences after the player's first recipe.
  • Resting sequences, although only if the player has previously rested at a particular spot.
  • The beginning of a Glitz Pit match the player has already competed in that is not special (like a first time rematch).
  • Boss cutscenes if the player had a Game Over from that fight.
  • Powering up with Merlon and Chet Rippo.
  • The effect of a charm spell in a battle.
  • Sailing the Black Skull.
  • The Excess Express starting and stopping.
  • Entering and leaving the Palace of Shadow through the Thousand-Year Door.

By location

Rogueport

• The garbage pail in Professor Frankly's house can be interacted with from the beginning of the game.
• One-time items sold in the Toad Bros. Bazaar, such as the Contact Lens, always replace the Fright Mask sold at the shop until they are purchased instead of the Mushroom.
• The Lovely Howz of Badges has a box at the end of the counter that stores badges sold at the shop that aren't currently on display on the counter. Mario can interact with the box to purchase these badges, but their prices are inflated compared to their display prices.

Rogueport Underground

• Merluvlee can provide her predictions as soon as Mario first enters Rogueport Underground without requiring the player to visit the Thousand-Year Door first.
• Dazzle is found on the opposite side of the fallen pillar outside of Merluvlee's house, although he will return to his location from the original game after the player visits the Thousand-Year Door.

Pianta Parlor

• The minigame machines have been changed from slot minigames to picture matching minigames similar to the Spade Panel minigame from Super Mario Bros. 3. Both machines are different, with the machine on the left being a harder version of the machine.
  • The maximum amount of Pianta tokens that can be earned from these machines has been reduced to 50 for the Spicy machine. In addition, by winning the game, they are automatically added to Mario's currency rather than being scattered over the floor surrounding it like in the original.
• The player is no longer required to beat certain high-scores from the minigames, as they now keep track of the player's own high-scores instead of the defaults.
• Pianta tokens are no longer given or taken by Lahla at the Pianta Parlor.
• As in Super Paper Mario, an option exists to buy 50 pianta tokens for 150 coins.

  • Jammin' Jelly and Ultra Mushroom cost 80 Piantas instead of 67;
  • Money Money costs 450 Piantas instead of 234.

Petal Meadows

• The pillars meant to contain the Sun Stone and the Moon Stone and the rock-covered Warp Pipe can be interacted with as soon as Mario and Goombella arrive in the area, with Goombella notifying Mario that the pillars look like something should be placed inside of their indentations and that the rock "kind of reminds me of a pipe."
• Higher hills have replaced invisible walls in the background to prevent Mario and his partner from moving off-screen.

Petalburg

• A red Toad who was originally positioned outside the shop is inside it and gives advice about POW Blocks on Mario's first visit.

Path to Shhwonk Fortress

• In the first area, there is a large bush from which a Koopa Troopa emerges, initiating an ambush battle against a Koopa Troopa and a Goomba. During this battle, the player must first press to chase away a Shy Guy in the audience that attempts to throw a rock at Mario, then use the Hammer on the Koopa Troopa to make a stage prop fall on the enemies.
  • If the player equips a badge that affects battles, either one from Dazzle or the Pretty Lucky badge found in a hidden block in the Rogueport Underground, the game will softlock after this tutorial. This was fixed in the version 1.0.1. update.
• Inside the mini fortresses, the player fights the Bald Clefts and Bristles by using the Hammer to knock them off their pedestals instead of interacting with the pedestals. The player can still interact with the pedestals, but doing so only leads to Goombella hinting that Mario should hit the pedestals with his Hammer to fight the enemies.
• The door in the room with the Bristles can be interacted with, contrary to the original game.

Shhwonk Fortress

• Mario receives his first email on the Mailbox SP immediately upon leaving the fortress instead of in Petalburg like in the original game. Goombella also provides the player with a tutorial on how emails work instead of a tutorial text box.

Hooktail Castle

• The Dull Bones horde push Mario out into the previous room instead of outside the entire castle.
• The ceiling spikes no longer kill Mario before the timer reaches 0.

Glitzville

• The hotdog cutout standee next to the Hot Dog Stand can be interacted with for photo ops. The photo can either be zoomed in on the standee, zoomed out to include the stand, or zoomed far enough out to include the stadium entrance. While Mario puts his head in the standee, his active partner can also appear and make an animation or a pose, with a total of three per partner.
• When chasing the jumping egg by the Hot Dog Stand, the camera locks into place rather than continuing to track Mario.

Glitz Pit

• Mario no longer goes down a rank if he loses a match unless he becomes the champion a second time and loses against Rawk Hawk in the rematch battle, where he will then lose the champion status.
  • As a result, Mario can only fight Wings of Night and The Destructors through Exhibition Matches.
• The hologram screen in the lobby functions as a menu, listing every fighter and their ranking in the Glitz Pit.
• After reserving a match, Mario can interact with the locker room doors to cause the Glitz Pit Security to immediately enter the locker room to take Mario to the match instead of the player having to wait for them to arrive like in the original game.
• The battle condition against The Iron Adonis Twins during Chapter 3 is always to use a partner skill at least once, though different conditions can be given when fighting them after Chapter 3.
• The first cake gifted by Jolene no longer restores SP.
• Battle conditions are no longer given when battling Rawk Hawk. In the original game, Mario would always be given the condition of performing at least one Special Move, even though the player would still advance, regardless of whether or not the conditions were met in that match.

Twilight Town

• Mario and his partner can now jump and walk into the pumpkin patch.
• During the search for General White in Chapter 7, Mario must talk to either Mayor Dour or the Twilighter standing near the Twilight Shop to advance the quest-line instead of talking to the Twilighter in front of the inn like in the original game.

Twilight Trail

• There is a large movable stone that blocks the entryway to the shed.
• When encountering Doopliss subsequent times after failing to guess his name the first time, an option is given to guess again or immediately escape.
• In the Japanese version, the in-game keyboard no longer has the option to switch between hiragana and katakana when the player is prompted to guess Doopliss' name, instead only having a katakana keyboard.

Creepy Steeple

• The Buzzy Beetles no longer attack the player immediately on entering the second room in the well.
• The blocks controlling the position of the stairs become inactive when hit until the other block is hit.
• Mario can jump all the way down the stairs below Doopliss's room instead of having to walk down them from top to bottom.

Keelhaul Key

• There is a switch at the top of a cliff that makes a jump pad appear as a shortcut for this area.
• The lost Wedding Ring produces a sparkly effect over the bush containing it, making its hiding spot more obvious.
• The Fuzzies in the third area remain present after clearing Chapter 5. In the original game, they disappeared from this area after clearing the chapter.
• The Flower Fuzzy on the ledge no longer gets stuck mid-air if it falls off the ledge.

Pirate's Grotto

• A new ambush battle occurs when the player reaches the Bill Blaster corridor room's eastern exit after obtaining the boat transformation. The enemies in this battle are a Lava Bubble, an Ember, and a Bulky Bob-omb.
• After completing Chapter 5, the barrels in the area where Mario rescued shipwrecked Toads respawn, allowing the player to more easily access the other areas of the Grotto instead of having to backtrack to the entrance.

Excess Express

• The note that Beldam leaves is an inventory item called the Threatening Note.
• After clearing Chapter 6, when riding on the Excess Express, the player is given the option to either stop at Riverside Station or travel directly to the destination point (Poshley Heights or Rogueport). In the original game, the player was forced to stop at Riverside Station first.

Riverside Station

• The four turning colored platforms in the Machinery Room stop in a preset pattern. The pattern for which the player must use to cross them is as follows: yellow, green, pink, green, pink, blue.

Poshley Heights

• After obtaining the Garnet Star, the player no longer needs to exit the Poshley Sanctum to trigger the Peach intermission. It is instead triggered after the conversation with Pennington after emerging from the Warp Pipe from the painting.

X-Naut Fortress

• There are four Security Keys and card terminals for Sublevel Three instead of three like in the original game. A new purple Security Key replaces the blue one originally there, with the latter now appearing in the restroom of Sublevel Four.
  • The Elite X-Naut battle in the restroom is an ambush battle instead of a regular battle. It must be won to obtain the blue Security Key.

Palace of Shadow

• The camera pans over the edges of the first lake bridge, revealing items to the player.
• In the torch maze room, the torches on the left side can be lit, requiring the player to backtrack several times for the puzzle to be solved.
• The doors inside the Tower cannot be opened until the player inserts the Star Stone into the slot at the top of the tower.
• Solving the puzzles requiring Flurrie and Bobbery in their respective rooms in the Palace of Shadow Tower reveal blue ! Blocks to make the treasure chests containing Tower Keys appear. In the original game, solving the riddles just revealed the treasure chests.
• The block the Ultra Hammer is required to smash is more obviously hidden.

Pit of 100 Trials

• Should the player get a Game Over on any floor, they are given the option to repeat that floor rather than being forced to start from the beginning.

Intermissions

• When Peach dances with her hologram, the player must hold the indicated buttons instead of just pressing them. is also a possible button that appears.
• When Peach enters Grodus's room while disguised as an X-Naut, she is no longer able to roam freely around the room and Grodus is now standing by his chair instead of in the middle of the room.
• When pausing during Bowser intermissions that involve traversing a level, the player can pause gameplay or retry the level. Selecting retry restarts the level on the next life.

Item changes

• The player can hold fifteen items in their inventory by default instead of ten like in the original game. The Strange Sack item as a result only increases the item capacity by five to remain twenty.
• As in the Nintendo Switch remake of Super Mario RPG, the coin limit has increased from 999 coins to 9,999 coins. In turn, Hooktail now makes a false offer to grant Mario 10,000 coins instead of 1,000, and, when the Money Money badge is equipped, the max number of coins per battle has increased from 32 to 99. In addition, if Mario gives Lumpy the maximum amount of 300 coins prior to the end of Chapter 4, he will receive the full amount of 999 coins from Lumpy after the end of Chapter 6 even if he already has coins on hand, unless he already has over 9,000 coins on hand.
• The pianta token limit has decreased from 99,999 to 9,999.
• Charlieton appears in Boggly Woods to sell his wares, including Mushrooms, Honey Syrups, Fire Flowers, Sleepy Sheep, POW Blocks, and Mini Mr. Minis.
• If the player picks up a new item when the inventory is full, they can immediately use a healing item (whether or not it is item they picked up) without having to discard something first.
• Players can now directly sell items in their storage without having to withdraw them first.
• Some badges' sell prices have changed.
• In the Happy Lucky Lottery, the top prize badges Lucky Day and Power Plus are switched.
• Item shops show the quantity of the player's consumable items, similar to shop displays in Paper Mario: Color Splash, and their shop points when talking to a shopkeeper.
  • Storing or withdrawing an item no longer closes the selection menu, allowing faster retrieval/deposits of multiple items.
• Some of Charlieton's item prices in Rogueport have increased.
• Charlieton now sells Ultra Mushrooms instead of Super Mushrooms and Jammin' Jelly instead of Maple Syrup in the Pit of 100 Trials.
• Any Zess T.-made items the player obtains outside Zess T.'s kitchen, such as Trouble rewards, are added to the Recipes list regardless of whether the player has already made them or not.
• To accommodate for the addition of the Warp Pipe Room, the Shine Sprite and the FP Plus badge from the original rooms are located behind a large yellow block and a large stone block respectively at the back of the Warp Pipe Room.

Regular items

• The Life Mushroom revives Mario if he loses all of his HP on the field in addition to doing so in battles.
• Sleepy Sheep was altered to last only 3 turns (Sleepy Stomp still retains the original 5).

Text and localization changes

Main article: List of Paper Mario: The Thousand-Year Door (Nintendo Switch) text changes

The remake features several changes to the game's script, including character dialogue and other forms of text. These changes were made to either remove stereotypical depictions or references to terms with pejorative meanings, adjust the speaking tone of several characters, correct mistranslations and other errors, or make certain texts closer to the original Japanese script. Notable changes include the following:

• The game has been translated into Chinese (Simplified and Traditional), Dutch, Canadian French, Latin American Spanish, and Korean. Notably, these languages were previously not available in the original game.
• The game's logo in international regions has been redesigned to closely resemble the Japanese logo of the original game. Conversely, the Japanese logo is primarily written in English, matching the design conventions of the series's Japanese logos from Super Paper Mario onward.
  • The international box art for the game reflects the Japanese box art of the original game.
• The "END OF CHAPTER" text that appears after collecting a Crystal Star has been replaced with "CLEARED!".
• The Yoshi (which is one of Mario's partners) is referred to as "Yoshi Kid", including his name in the in-game soundtrack.
• Some locations have been given more descriptive names, such as Rogueport Sewers being renamed to Rogueport Underground, the areas between Petalburg and Shhwonk Fortress being collectively referred to as Path to Shhwonk Fortress instead of Petal Meadows, and several rooms in the Palace of Shadow being given descriptive names.
• Descriptions of various items have been rewritten to clarify or remove false information entirely. Notable examples include Thunder Bolt and Thunder Rage, with their descriptions in the original game falsely claiming that they could stun enemies; this was fixed in the remake to correctly state that they deal 5 damage to enemies.
• Several translation errors, typos and continuity errors were corrected, which include:
  • The tattle for Sky-Blue Spinies now correctly states that they come out of "Spiny Eggs" instead of "pipes", previously a translation error in the original game.
  • In the email sent by Pine T. Jr., Bubu is corrected to Li'l Oinks.
  • Every instance of Yoshi Kid referring to Mario by his actual name instead of Gonzales prior to the ending has been corrected.
• Hooktail's weakness is now stated to be frogs instead of crickets, aligning with the original Japanese script. In regards to this, the Attack FX R badge found in Hooktail Castle has been replaced with Attack FX G, which now makes frog noises.
• Hooktail is consistently referred to with feminine pronouns throughout the entire game. Any terms referring to her that evoke masculinity are either remove or replaced with female or neutral alternatives. For example, Koops refers to her as a "gal" instead of a "guy" if he is the active partner while Hooktail is eating the audience.
• Vivian's portrayal as a transgender woman is more overt, with the Japanese version adding in dialogue where she says 「体は　オトコのコだけど ココロは　カワイイ　オンナのコなの」 ("I have a boy's body, but my heart is a cute girl's!"). Her party member description is changed from 「オンナのコのようで　ホントは　オトコのコ」 ("She looks like a girl, but she's really a boy,") to 「体は　オトコのコで　ココロは　オンナのコ」 ("She has a boy's body, but the heart of a girl."). This portrayal is also reflected in the remake's English and German localizations, whereas the English and German releases of the GameCube version omitted all references to the subject. In addition, the remake's Japanese script also removes several lines in which Vivian is referred to as a male, and Goombella's Tattle about Vivian removes any mentions of her gender.

Graphical changes

General

• The entire game has a higher screen resolution and a more detailed look, using a more realistic crafted style similar to entries starting from Paper Mario: Sticker Star onward.

• 3D objects such as pigs have visible construction seams on them.
• Surface textures are generally more reflective.
• Dynamic lighting is present extensively in many areas.
• The Crystal Stars have a more realistic shiny texture than the original game.
