Version Differences
Welcome to Kinoko Town!

Unused Music

Two unused tracks can be found in the game's soundtrack, which seem to be early versions of the intro/title themes. The segment at 0:50 is the same in the final intro theme, accompanying Bowser's appearance. The second track would be for the title screen following it. Interestingly enough, the beginning of the first track was reworked into the song played in the ending scene after Bowser's Castle is destroyed.

Truncated Music

The intro song is actually split into two parts. The first part plays until 1:07 before being replaced by the second part, but the actual song is 1:27 long.

When encountering a Blooper, this song plays; however, only the first two notes can be heard in-game before the battles start, as the game automatically cancels the Blooper text box.

Unused Music Variations

Some songs in the game have unused variations. Details on the Notes page.

Goomba Village

It's a sped-up and shorter version of the normal song.

Detective Mario

Starts mid-song, ends abruptly.

The End Theme

Begins as a sped-up version of the normal song, then returns to normal tempo when the "Chanterelle's Song" segment starts.

Lakilester's "Spike's" Theme

Unused Models

Broken "Fully Cracked" Frozen Lake


The frozen lake in Shiver City has a third, fully-cracked model that would've appeared if Mario ground pounded the ice three times. Since Mario gets kicked out of the area after the second ground pound and the lake resets upon re-entering the area, the third model can't be seen normally.

It can be seen by performing a glitch or by using a GameShark code.

Unused Enemies

Fun with palette swapping.
You can see the working enemies in action here.

(Images: Retriever II)

Albino Dino


These enemies appear as living statues in the Crystal Palace, but are never actually fought. However, they can be fought using GameShark codes. They only know one attack, which is a charging ram that hurts Mario. Goombario even has a tattle for them:

This is an Albino Dino.

Albino Dinos are the guards
of this frosty place.
Max HP: 8, Attack Power: 4,
Defense Power: 4

Fire attacks won't work.
Their defense power is huge,
so let's reduce their HP
steadily using our strongest
damage-dealing attacks.

Aqua Fuzzy


A blue Fuzzy. All that's been found is the enemy name and blue palette.

D. Paratroopa


A winged version of the Dark Koopa enemy that was just never used. However, this enemy would later go on to be used in the game's sequel. They too can be fought with GameShark codes. Their attacks are basically the regular Paratroopa's attacks sped up. If jumped on, they lose their wings and become Dark Koopas. Goombario has a tattle for them as well:

This is a D. Paratroopa.
D. Paratroopas are Para-
troopas who live in the
Toad Town Tunnels.
Max HP: 8, Attack Power: 3,
Defense Power: 2

Hammer attacks won't work
because they're airborne.

They'll lose their wings if
you jump on 'em.

They'll become Dark Koopas
when they fall, but be careful!
They'll do a dizzy attack
once they're grounded.

Red Goomba


This is not the sub-boss with the same name. There are two different entries for Red Goomba in the enemy name table.

R Paragoomba


This is a Red Goomba with wings. Yep. Red Paragoombas originally appeared in Super Mario Bros. 3, which this game draws a number of elements from.


To do:
Looking in the scripts extracted with the Star Rod tool, it seems like there are three enemy versions of Whacka. Also, maybe he's less buggy in the Japanese version of the game.

Interestingly, Whacka has an entry in the enemy name table and a tattle! Based on the tattle, it seems that earlier in development, instead of disappearing after being hit enough times, he would attack. Whacka also crashes the game if he does an attack.

A Whacka would eventually appear as a superboss in the Thousand-Year Door remake; similarly to the unused tattle, he can only be challenged by hitting him in Keelhaul Key until he flees, then revisiting the last floor of the Pit of 100 Trials after defeating Bonetail.

Japanese English
Japanese Translation English
あのタンコブって タコヤキみたいだよね
It's Whacka.
That Bump on his head kinda looks like
takoyaki, doesn't it?
This is a Whacka. That Bump on
his head looks like a donut hole.
マリオが あんまり 何回もたたくから
おこって 出てきたみたいだよ
It seems he's gotten mad because 
you hit him so many times.
You probably shouldn't have hit
him so much. He looks a little

Unused Party Members

PaperMario GoombariaPartner1.png PaperMario GoombariaPartner2.png

You can add Goombaria as a party member by using the GameShark code 8010F2F4 0001. She'll appear at the end of the party member list (by pressing C-Right) after all others, but with Kooper's icon.

She'll follow Mario around on the overworld like normal party members, but she has no special ability. She'll also show up on the Change Member menu inside a battle, but she doesn't appear to have anything programmed for battles and thus will crash the game. If she is the currently active party member, pressing C-Right to bring up the party member menu will crash the game unless you're playing the Japanese version, in which case an unused option will be spawned but not selectable.

Goompa is technically another 'unused' party member. He does join you at the beginning of the game, but he is not active in battle. However, by switching a status flag, or by performing a glitch known as "Goombario Skip", you can make him active. He has up to 4 abilities, but none of them are programmed in so they do not function. Just like Goombaria, if he is active, pressing C-Right to bring the party member menu will crash the game unless you're playing the Japanese version.

Twink, who is normally alongside Princess Peach, can also be alongside Mario. If he is the currently active party member, like Goombaria and Goompa, opening the party member menu will crash the game.

Internal Map Group Names

In addition to the short abbreviated map group names, Japanese map group names exist as Shift-JIS text in the ROM. Only "ID", "Abbreviated Name" and "Japanese Name" in the below table are from the data in the ROM. The rest of it is supplementary.

Unused Text

To do:
Is "Don't wear more!" (from the Badges menu) used? The French and Spanish localizations left it untranslated, so I'm guessing no.
Japanese (ID 00-000) International (ID 00-000)

This message has the distinction of being the very first message in the ROM, making it, most likely, a test. That blank area in the Japanese script is a single space character.

Japanese (ID 02-039) English (ID 02-038)
Have at you!

Like Chan and The Master, Lee has an opening line for his battle with Mario. Instead of using it, though, he goes straight to his copy ability, which uses a different line.

Japanese (ID 32-402) English (ID 29-374)
ここで ジャンプすると
20コインを 使って
レバーを たたくことができます
Jump here and hit the lever 
for 20 coins.
Do you want to jump?

This comes right after the text for the sign by the Li'l Oink Farm.

(Li'l Oink Farm text: Original TCRF research)
PaperMario64 RedFlower.png
Munch munch munch...
Ummm... I really don't like this
type of berry at all.
You'd better get me a better
flavor, or you can't go through.

Supposed to be spoken by the Red Flower Gate Guard in Flower Fields if he were given a Yellow or Blue Berry. They're impossible to obtain before going through his gate, making this unused. You can still see it by hacking either berry into the inventory.

Monty's Hole

An unused string located among the list of enemy names. Presumably, the holes that the Monty Mole enemies pop out of would have been possible to target, but this is impossible in the final game.

(Source: Original TCRF research)
Act Later

An unused command for the Strategies menu that doesn't appear to have any functionality associated with it. While the English is kind of ambiguous, the Japanese name (あとで こうどう, "Act Afterward") suggests that this would have deferred Mario's turn and let the enemy go first.

Message ID Japan (50-XXX) North America (46-XXX) Europe (46-XXX)
115 (JP)
126 (NA/EU)

The end credits block contains a number of unused dummy strings.

  • Two are spare "Mario Story" strings, which were not changed to "Paper Mario" internationally (since they are never displayed). One of them (as well as one of the "job dummy" placeholders) was used to credit translation manager Hiro Yamada in the international versions.
  • Bizarrely, the North American version introduced a typo in strings 094 to 096, rendering them as "dummuy".

Unseen Behavior

Post-Prologue moves without Action Commands

At the end of the game's prologue, Mario receives the Lucky Star and the ability to perform action commands, which can be used by Mario, his partners, and even bosses. Most attacks cannot normally be seen being performed without the action commands enabled. Some attacks do work correctly, but others have strange side effects:

  • Kooper's Shell Toss and Power Shell softlock the game.
  • Parakarry's Shell Shot and Lakilester's Spiny Flip always have the action command on.
  • Parakarry's Air Lift has a command bar, but it doesn't accept any input.
  • Watt's Electro Dash and Bombette's Body Slam accept input as if you had the action command, but there doesn't seem to be a way to deal more damage with them.
  • Partner abilities that inflict status effects on Mario or enemies will always fail.
    • Turbo Charge still makes the boosted sound.
    • Sushie doesn't spray water over Mario when performing Water Block.
    • Lakilester doesn't hold up a Spiny Egg when performing Spiny Surge.
  • Buzzar's Wind Blast fails to inflict any damage, and Mario cannot escape from Grapple Drop.
  • Huff n' Puff's Wind Breath will always deal the same amount of damage.

Items Used On Partners

A few select items were intended to be used on partners. These items are the Mushroom, Life Shroom, Super Soda, and Tasty Tonic.

  • Mushroom: As seen in the video, this was intended to be used on partners to recover their status from being 'knocked down' for five turns. Mario throws the item to the partner.
  • Life Shroom: Does the same as Mushroom except that it heals for ten turns. Mario throws the item to the partner.
  • Super Soda: Seemingly does nothing. Mario goes to throw the item to the partner, but the graphic turns into a present and then falls onto the partner.
  • Tasty Tonic: Does the same as Mushroom/Life Shroom except it heals the partner entirely. Mario raises his hands like he does for any item usage and it instantly heals the partner.

Why these functions go unused is uncertain, but they still exist in-game and function properly.

Defense Command

PM64 DefenseIcon.png


There is a name string, icon, and some unfinished functionality for a "Defense" command similar to the one from The Thousand-Year Door (which replaced this game's "Do Nothing"). Modifying some memory when the Strategies menu is open will allow it to be used. Mario flips through a few animations when used at first but then goes into a defensive pose. It functions completely as well: it lowers damage taken by one, and you can time your block to reduce the damage by one more point too! Why this was ultimately scrapped is unknown.

No Boots

The hot new Paper Mario challenge run: "Barefoot Mario"

While impossible in normal gameplay, an equipment status for not having any boots on (similarly to the hammer at the beginning of the game) exists and can be enabled with the following GameShark codes:

Version Code
JP 8010F450 00FF
US 8010F290 00FF
EU 8010DD90 00FF

It doesn't prevent Mario from jumping in the overworld, but it does keep him from using it to get First Strikes, and the command is disabled in battle (saying there's nothing to jump on, even when that isn't the case).

Unused Badge Selling Prices

To do:
Are the selling price data and the badge shop price data one and the same? If so, update the description.

By using the Badge Duplication glitch or GameShark codes, it is possible to get badges into the normal item inventory. This allows badges to have normal item behavior, including the ability to sell badges. Strangely enough, all badges have set prices, despite being unable to sell them without using exploits. Some of these badges are available on Rowf's Badge Shop and have the same price there as they have here. This could mean that at some point, either all badges were meant to be available at said badge shop, or that regular badges could be sold at regular item shops. Badge selling was eventually fully added to Paper Mario's sequel, Paper Mario: The Thousand Year Door.

Badges available in Rowf's Badge Shop are marked in blue, while the unused badges (which cannot be obtained in normal gameplay) are marked in bold.

Crash Handler

To do:
Find out if there's a way to trigger the crash handler in the Japanese version, as well as find out if it's in the PAL and iQue versions.
Paper Mario Crash Screen.png

Paper Mario has a crash handler similar to other N64 games by Nintendo (such as The Legend of Zelda: Ocarina of Time). It can be accessed by triggering a fatal exception through exploiting one of the game's various glitches or through tilting the cartridge. Although it only appears to be triggered in the North American version, the error cause texts and other data related to the handler can still be found in the Japanese ROM at offset 0x73210.

A few seconds after the game crashes, the exception handler prints information about the state of the Nintendo 64's processors and coprocessors at the time the game crashed. The crash handler's information can be broken down as follows:

  • THREAD: The thread ID.
  • The error names (in parentheses) are standard MIPS exceptions. In the example, the error is TLB EXCEPTION ON LOAD; TLB (translation lookaside buffer) exceptions are related to virtual memory.
  • PC: Program counter (where was the CPU running code in when the exception occurred). Likely actually the EPC register in the exception handling coprocessor.
  • SR: A MIPS state/control register. Should be interpreted on a bit basis: bits can either signal a state or control a setting for the CPU. Likely actually the Status register in the exception handling coprocessor.
  • VA: The BadVAddr register in the exception handling coprocessor: address in memory where the exception occurred.
  • AT, V0-V1, A0-A3, T0-T7, S0-S7, T8-T9, GP, SP, S8, RA: State of registers. Since MIPS has general-purpose registers, they are named as in the "O32" calling convention, one of the more common ways to label the registers. Here's the purpose of these registers according to O32:
    • AT is an "assembler temporary" register used in some common CPU operations.
    • V0-V1 contains return values of functions.
    • A0-A3 contains function arguments.
    • T0-T9 are temporary registers.
    • S0-S7 are saved temporary registers, values that should never be changed by any called function (so after calling a function, values of S0-S7 will always be the same as before calling it).
    • GP has the global pointer used to access global variables.
    • SP is the stack pointer.
    • S8 (also called FP in MIPS programming) is the frame pointer, which contains the location of the stack frame within memory.
    • RA contains a return address. This is used when calling "leaf" subroutines - as in subroutines that do not call other ones, since it's faster than having the return address in the stack. This sort of register is usually called a link register.
  • MM: The opcode that was attempted at the time of the crash.

The rest are values from the floating-point coprocessor:

  • FPCSR: FPU control and status register.
  • F0-F30: Floating-point general purpose registers. There are actually 32 of these registers, but Paper Mario seems to use them in 2 register pairs to store double-precision (64-bit) floating-point numbers.
(Crash handler breakdown: CosmoConsole)


Duplicate Luigi Actors


In the Smash Attack mini-game, one of two mini-games found in the Playroom, ten(!) Luigi actors are loaded underneath the room. Paper Mario stores all of a room's actors out-of-bounds when not in use; however, Luigi is never seen in this room. The fact that there is not just one, but ten Luigi sprites loaded in the room heavily implies that Luigi would have originally popped out of a block instead of a picture of Peach.

(Source: Stryder7x)

Invisible Actors

Many objects in the game that require movement only for cutscene or aesthetic purposes use pre-existing actors to control their movement. The actors used to control the movement of these objects are not meant to be visible, but can be made visible through hacking.

Examples of objects controlled by actors include:

  • The jump pad in the tree outside Toad Town's Goomba Road entrance, which is temporarily controlled by a red Toad actor when it is knocked down.
  • The Li'l Oinks in Toad Town, whose movements are controlled by blue Toad actors.
  • The Snowmen in Shiver Snowfield, whose jumping animations are controlled by Bumpty actors.
  • The letter to Mayor Penguin in the same room is also temporarily controlled by a Bumpty actor when it is knocked off the tree. Collecting this letter before the animation completes causes the game to throw an exception and crash.
(Source: mov Mario, Paper (1/2))

Misaligned Bomb Hitboxes

Objects that can be shaken by Mario's hammer, such as trees, can also have Bombette exploded by them for the same effect. Strangely, these two functions are assigned separate hitboxes; even stranger still, the hitbox that can be triggered using Bombette is sometimes not aligned with the hammer hitbox. The most notorious example of this is in the train station area of Toad Town, where the bomb hitbox for the tree that activates the pipe to the Playroom is placed at the opposite end of the room at X: 265, whereas the tree object itself is located at X: -265.

Electrocuted Goombas

"Can't you feel it in your bones? Do Goombas have bones?" Moments later, he had an answer.Truly, a "shocking" development.

Goombas and their variants have unique "X-ray"-style sprites, which presumably would have been used when hitting one with an electrical attack. While they are used, it is only if a Goomba attacks Mario while he's wearing Zap Tap. No direct electrical attacks will trigger the sprite.

No other enemy in the game has an equivalent.
