EarthBound/Control Codes

This is a sub-page of EarthBound.

General information

Every window has the following six "registers", divided into two parts:

• Active Memory
  • Working Memory (4 bytes)
  • Argumentary Memory (4 bytes)
  • Secondary Memory (2 bytes)
• Storage Memory
  • Working Memory Storage (4 bytes)
  • Argumentary Memory Storage (4 bytes)
  • Secondary Memory Storage (2 bytes)

Storage Memory is simply used to store copies of the registers in Active Memory. The only thing that can be done with it is to copy values to and from Active Memory using codes 1B 00 and 1B 01.

Working Memory is generally used to hold return values from control codes, and is also used in controlling program flow.

Argumentary Memory (also called Argumentative Memory) is usually used to pass values to control codes. That's why it's called "argumentary", because it contains the argument of the control code in programming terms.

Secondary Memory isn't used very much, but it is used in forming simple loops and can be used as an extra register, since it can be copied to and from the other active registers.

Arguments for control codes may be found listed in the Standard Argument Listing, or in PK Hack itself.

00-17 - General parsing

[00] (Line Break)

This code causes a line break in a text window. The cursor will drop down to the start of the next line. If the cursor is already at the bottom of the window, the text will simply be scrolled up and will start printing again at the start of the same line. As commonly used in EB, a [00] will either be followed by a bullet symbol (type @ in most EB editors) or two spaces to keep everything nice and lined up.

[01] (Start on Blank Line)

This code behaves similarly to [00]. It will cause the text window's cursor to drop down to the next line. However, this code will have no effect if the cursor is already on a blank line. This code is useful for ensuring that text will be printed on a new line when you do not know what text will precede it, such as after a menu or conditional jump.

[02] (Stop Parsing)

This code marks the end of a text block or text string. Upon reading a [02], the engine will stop looking at this particular block and go on with whatever it was doing prior to reading it. It's very important to put this at the end of all text blocks! Otherwise, the engine will just keep surfing through ROM data until it hits one, or enough non-text code to make it glitch horribly. Ever seen the infamous "Multi-Task code" that makes the engine keep reading seemingly unrelated text blocks endlessly (Game Genie EE64-54A1)? Well, that's exactly what we're talking about here. That code merely disables the effect of the [02] control code.

[03] (Halt Parsing with Prompt - Variable)

This code pauses text reading and waits until the player presses the A button. It also displays the blinking triangle along the bottom of the window. Note that its effect changes when in-battle: When text speed is set to medium or fast, it will simply act as a short delay. If you want to make sure it stops with the blinking triangle when in battle, you should use [14] (Halt Parsing with Prompt) (see that code's entry for more details). Common usage of [03]'s in EarthBound is to place it before [00] (Line Breaks). That way, the player won't miss anything that scrolls by too quickly.

[04 XX XX] (Toggle On Event Flag)

This code sets a value of 1 to event flag $XXXX. The flag is then considered to be toggled "on." Remember to reverse the flag number - to toggle on $0123, you would use [04 23 01].

[05 XX XX] (Toggle Off Event Flag)

This code sets a value of 0 to event flag $XXXX. The flag is then considered to be toggled "off." Remember to reverse the flag number - to toggle off $0123, you would use [05 23 01].

[06 XX XX YY YY YY YY] (Event-Dependent Pointer)

This code checks the status of event flag $XXXX. If its value is set to 0x01 (Boolean True), it jumps to pointer $YYYYYY and continues reading from there. If the flag is set to 0x00 (Boolean False), the code does nothing and the engine simply continues past it.

[07 XX XX] (Return Event Flag)

This code checks the status of event flag $XXXX, and fills the Working Memory data with that value. This is useful if you need to use the value of an event flag in conjunction with the Boolean Pointer codes, [1B 02 XX XX XX 00] (Boolean-False Pointer) and [1B 03 XX XX XX XX] (Boolean-True Pointer) (see those codes' entries for more information). Note: The code string [07 XX XX][1B 03 XX XX XX XX] is exactly the same as using a [06 XX XX YY YY YY YY] (Event-Dependent Pointer), except it overwrites whatever's currently in Working Memory.

[08 XX XX XX XX] (Reference Pointer)

This code references the data at $XXXXXX. It will read all the text there until it reaches a [02] (Stop Parsing) code. When that happens, it will continue parsing from the [08 XX XX XX XX] code that initally made the reference. Contrast this against the [0A XX XX XX XX] (Jump Pointer) (see that code's entry for more information).

[09 XX (YY YY YY YY)] (Multiple-Address Jump Pointer)

This code behaves similarly to [0A XX XX XX XX] (Jump Pointer); however, it has the added benefit of being able to have multiple branching pointers within itself. This one does take a bit of explanation. The value of the first argument, $XX, determines how many pointers there will be in the code. Codes that change lengths based upon the value of an argument are somewhat rare, but this one is fairly straightforward. For example, if $XX were 0x01, the format of the code would be [09 XX YY YY YY YY]. However, if we changed $XX to 0x02, the format would change to [09 XX Y1 Y1 Y1 Y1 Y2 Y2 Y2 Y2]. If $XX is 0x03, the code becomes [09 XX Y1 Y1 Y1 Y1 Y2 Y2 Y2 Y2 Y3 Y3 Y3 Y3]. By this point you should get the idea. The upper limit on this is 0xFF, or 255 pointers, though one would hope you'd never have to fill in that many pointer spaces. [09 XX (YY YY YY YY)] starts by checking the Working Memory. It then compares that value against $XX. If the number in memory is either 0x00 or higher than $XX, the code will be ignored and the text will continue parsing past it. Otherwise, the code will select a pointer based on the memory value. If the value is 0x01, it will use the first pointer in the code's list; if the value's 0x02, it uses the second one, and so forth for the rest of them. The code jumps to the data at the selected pointer and parses from that location as normal. As with [0A XX XX XX XX], it will not return to the location of the original [09 XX (YY YY YY YY)] when it reaches a [02] (Stop Parsing) code; it will simply stop parsing.

[0A XX XX XX XX] (Jump Pointer)

This code jumps to the data at $XXXXXX and parses from that location as normal. It will not return to the location of the original [0A XX XX XX XX] when it reaches a [02] (Stop Parsing) code, it will simply stop parsing. Contrast this against the [08 XX XX XX XX] (Reference Pointer) (see that code's entry for more information).

[0B XX] (Perform Boolean True Check - Equal to Working Memory)

This code will compare the value in Working Memory to $XX. It will then change the value in Working Memory based on the result; the value will be set to 0x00 (Boolean False) if it's not equal to $XX, or 0x01 (Boolean True) if it is equal. This code lets you run the Boolean pointers, [1B 02 XX XX XX XX] (Boolean-False Pointer) and [1B 03 XX XX XX XX] (Boolean-True Pointer), based on the results of ANY code that stores data to Working Memory. This allows for lots of flexibility in terms of conditional text based on whether you have a given item, who's in the player's party, or even what side the player is checking something on, just to cite a few examples. Keep in mind, though, this code DOES delete what value is in the Working Memory in the process! If you wanted a sequence of [0B XX] checks for various values, you'd want to use [1B 00] (Copy All Memory to Storage) before each [0B XX] code and [1B 01] (Copy All Storage to Memory) after any boolean pointers following them to make sure that the original value being checked is not lost (see those codes' entries for more information).

[0C XX] (Perform Boolean False Check - Equal to Working Memory)

This code will compare the value in Working Memory to $XX. It will then change the value in Working Memory based on the result; the value will be set to 0x00 (Boolean False) if it is equal to $XX, or 0x01 (Boolean True) if it's not equal. This code lets you run the Boolean pointers, [1B 02 XX XX XX XX] (Boolean-False Pointer) and [1B 03 XX XX XX XX] (Boolean-True Pointer), based on the results of ANY code that stores data to Working Memory. This allows for lots of flexibility in terms of conditional text based on whether you have a given item, who's in the player's party, or even what side the player is checking something on, just to cite a few examples. Keep in mind, though, this code DOES delete what value is in the Working Memory in the process! If you wanted a sequence of [0C XX] checks for various values, you'd want to use [1B 00] (Copy All Memory to Storage) before each [0C XX] code and [1B 01] (Copy All Storage to Memory) after any boolean pointers following them to make sure that the original value being checked is not lost (see those codes' entries for more information).

[0D XX] (Copy to Argumentative Memory)

This code will copy the value stored in either Working or Secondary Memory into Argumentary Memory. It will not affect the value stored in the register copied from. The $XX value determines what memory to copy from, where a value 0x00 indicates Working Memory, and 0x01 indicates Secondary Memory.

[0E XX] (Store to Secondary Memory)

This code stores the value in $XX to Secondary Memory. There are not many codes that manipulate Secondary Memory. However, using [0E XX][0D 01] is the simplest way to load a constant value into Argumentary Memory.

[0F] (Increment Secondary Memory)

This code will increase the value stored in Secondary Memory by 1. In general, this code is used to create simple loops.

[10 XX] (Delay Parsing)

This code stops the text parsing briefly for dramatic purposes. The duration of the pause is controlled by the value of XX. The engine reads this value as units 1/60th of a second long. Therefore, a one-second pause would be [10 3C], a two-second pause [10 78], and so forth. The maximum value - 0xFF - is a 4.25 second pause. These can be used any time in text when you want a pause of a specific length. String them together to achieve longer pauses.

[11] (Create Selection Menu from Strings)

[12] (Clear Text Line)

This code erases all of the text on the current line and moves the cursor back to the beginning. This is often used in text menus, number selectors, and other similar cases. It's not commonly used in cases of generic conversational text.

[13] (Halt Parsing without Prompt)

The [13] code is highly similar to the codes [03] (Halt Parsing with Prompt - Variable), and [14] (Halt Parsing with Prompt). Like those other two, it stops parsing text until the player presses the A button. However, the main difference here is that it does not display the blinking triangle prompt. This is commonly used when you want the player to have to hit A, but don't have a text window open at the time. Also, it's standard procedure to place a [13] before a [02] (Stop Parsing). That way, the player must confirm the end of the block and closing of the window, but without leading them to believe there's more text to come as a [03] might.

[14] (Halt Parsing with Prompt)

This code is virtually identical to [03] (Halt Parsing with Prompt - Variable). It pauses the text, displays a blinking triangle prompt, and waits until the player presses the A button. However, the main difference is that its function does not change when you're in battle. This is the code you want to use if you're composing text to be displayed in battle.

[15 XX] (Display Compressed Text/Bank 0)

[16 XX] (Display Compressed Text/Bank 1)

[17 XX] (Display Compressed Text/Bank 2)

These three codes all work to make EB's text more efficient. Each code links to one of three banks of text. Each bank contains 256 (0x00 - 0xFF) different phrases, words, and character clusters. As the engine parses the code, it will reference entry $XX from the proper bank, and substitute the text in that entry for the [15/16/17] code itself. JHack's text editor automatically compresses its text, so you won't have to manually convert for these codes. However, if you're entering your text in another program (say, a hex editor), you can also use CT-Boing Ultra to compress it.

18 - Window management

[18 00] (Close Current Window)

This code closes the most recently-used text window. Typically, only one window will be open at any given time, but if there are multiples open due to [18 01 XX] (Open Text Window) or another code, the one that was most recently opened (or most recently parsed in) will be the first to go. If you want to close a specific window but aren't currently parsing in it, use a [18 03 XX] (Switch To Window) code (see the above codes' entries for more information).

[18 01 XX] (Open Text Window)

This code opens a text window and selects it as the focus window for parsing text. The $XX argument determines the size and position of the window, which it reads from a database in the ROM. Note that the engine will not support opening more than one of the same window. If window type $XX is already open, this code will close it and then open it again, effectively clearing it like [18 06] (Clear Current Window).

[18 02] (UNKNOWN)

[18 03 XX] (Switch To Window)

This code selects the window type $XX as the focus for parsing text. Any text data read by the engine following this code will be displayed in this window. If a window is overlapping the one switched to, the engine will not bring it 'forward' so all of it is visible. NOTE: Do not use this code if the window type $XX has not already been opened! Attempting to switch to a closed window type will immediately crash the game.

[18 04] (Close All Windows)

This code, fairly straightforward, simply closes all opened windows. This does not need to be used at the end of a text block, as the engine automatically performs that action. However, in cases where animation, movement, or teleportation are used, one would be well advised to close the windows beforehand. If you wish to halt parsing of the text while windows are closed, [13] (Halt Parsing without Prompt) should be used rather than [03] (Halt Parsing with Prompt - Variable) or [14] (Halt Parsing with Prompt). The other two will display the triangle prompt icon floating in the top-left corner of the screen.

[18 05 XX YY] (Force Text Alignment)

This code forces text to appear in a specific location in a window. $XX is rendered as the X-axis offset (horizontal), and is measured in pixels. Text parsed after this code will start printing $XX pixels over from the left-hand side. $YY is rendered as the Y-axis offset (vertical), and is measured in rows (16 pixels each). Text parsed after this code will start printing $YY rows down from the top. This code is extensively used in the status menu, among other locations.

[18 06] (Clear Current Window)

This code eliminates whatever text that's displayed in the current window. The cursor will be returned to the top left corner of the window, as if it had just been opened.

[18 07 XX XX XX XX YY] (Compare Window Register to Number)

This code compares the number X to the window register given in Y (0 for working memory, 1 for argumentary memory, and 2 for secondary memory). It returns 0, 1, or 2 depending on if the register's value is less than, equal to, or greater than X, respectively. Note that an X of 0 does not access argumentary memory.

[18 08 XX XX XX] (UNKNOWN)

[18 09 XX XX XX] (UNKNOWN)

[18 0A] (Show Wallet Window)

This code opens a small window in the center-left of the screen, and automatically displays the amount of money on hand. This is used in various places, notably in the code for stores and telephones.

[18 0D XX YY] (Print Character Status Info)

When YY = 01, this code opens window 8 and displays the stats for character XX in it, as if the player went to the pause menu and chose "Status." If XX is 0, the value in working memory is used instead of XX. The character doesn't actually need to be in the party for this to work. After the stats get printed to the screen, script execution continues inside of the status window until the script manually switches away from it.

Functionality for YY = 02 appears to have been removed. All other values of YY do nothing.

19-1A

[19 02] (Load String to Memory)

[19 04] (Clear all loaded strings)

[19 05 XX YY YY] (Inflict Status Change)

Inflicts status change YY YY on character XX. See Standard Argument Listing for further information.

[19 10 XX] (Return Character Number)

This code returns to the register the ID value of whatever the party member is at a certain slot/position in the party. For example, if your current party consists of Ness, Paula and Jeff, but Ness is unconscious, using the control code [19 10 01] will return the ID value of 02, which corresponds to Paula. However, if Ness is revived, this very same control code will return the value of 01 instead, 01 being the value for Ness.

[19 11 XX] (Return One Letter from a Character's Name)

This code looks at the value in Secondary Memory, takes the letter in that position in character $XX's name, and puts its value into Working Memory. The corresponding values can be found in the Standard Argument Listing. Knowing this value generally isn't necessary, as this code is almost always followed by [0D 00][1C 03 00] to print the letter in question.

[19 14] (Return One Item from Escargo Express Storage)

This code looks at the value in Secondary Memory to determine which item to return: a value of 01 returns the first item, 02 the second item, etc. If there is no item at that position, this code returns 0. After returning the item, Secondary Memory is incremented so that the code can be used to get the next item immediately, without using [0F].

[19 16 XX YY] (Return Byte YY of Character's Status)

[19 18 XX] (Return amount of exp needed to levelup. Used in Dad's save text)

[19 19 XX YY] (Return YYth Item from Character XX's Inventory)

[19 1A XX] (Return XXth item in Escargo Express inventory)

This code sets working memory to the value of the $XXth item in item storage. If $XX is 0, the value in argumentary memory is used instead of $XX.

[19 1B XX] (Return Number of Strings Loaded with [19 02] for Window XX)

[19 1C XX YY] (Queue Item for Delivery/Pickup)

This code removes the YYth item in character $XX's inventory and puts it in the first free spot of a queue of 3 items, along with information about the item's original owner. If $XX is 255 ($FF), an item will be removed from the Escargo Express storage instead of a player's inventory. If $XX is 0, the value in working memory is used instead of $XX. If $YY is 0, the value in argumentary memory is used instead of $YY. The list of queued items can only hold three items; attempting to add more will result in the item being lost.

[19 1D XX YY] (Return Information about Queued Delivery/Pickup Item)

This code retrieves information about the $XXth item in the list of items queued for delivery/pickup. It sets working memory to the original owner of the item, and it sets argumentary memory to the actual item. If $YY is nonzero, that spot in the queue is made free for a new item to be added, removing the item from the list.

[19 1E] (Return Amount of Change. In other words, store the delta amount in the Result register. Related to [1C 0F])

[19 1F] (Return Battle Action Argument)

[19 20] (Return Number of Party Members)

[19 21 XX] (Return Category of Food Item)

This code checks the "type" field of item XX in the item configuration table. For foods, it returns 1, 2, or 3 into working memory depending on if the item is food, drink, or condiment (respectively). For other items, the result returned may not be useful.

[19 22 XX YY ZZ ZZ] (Return Direction from Character to Object)

[19 23 XX XX YY ZZ ZZ] (Return Direction from NPC to Object)

[19 24 XX XX YY ZZ ZZ] (Return Direction from Sprite to Object)

These three codes find the direction (1 through 8) from a source object $XXXX (type given in the control code description) to a different object $ZZZZ of type $YY. The valid types are 01, 02, and 03, corresponding to the characters, NPCs, and sprites, respectively. If $XXXX is 0, working memory is used instead of $XXXX. If $ZZZZ is 0, argumentary memory is used instead of $ZZZZ.

[19 25 XX] (Return Item ID of Condiment to Use on Food)

When used in a script for a party member doing a battle action, this code verifies that item $XX is a food item and searches the party member's inventory for the first condiment that can be applied to the food. If the item has the normal food item type and there is a condiment in the inventory, working memory will be set to the item ID of that condiment. Otherwise, if there is no condiment in the party member's inventory or item $XX is not food, the code will set working memory to 0. If $XX is 0, the value in argumentary memory will be used instead of $XX.

[19 26 XX] (Set Respawn Point to the Current Coordinates)

This code sets the coordinates to respawn at after dying to whatever the party leader's current coordinates are, and sets the destination of the unused "Teleport Box" battle action to warp point $XX, or the value in argumentary memory is $XX is 0.

[19 27 XX] (Return Value of a Statistic)

This code puts the numerical value of statistic $XX into working memory. If a statistic is not actually a number, the 3-byte-long pointer to the statistic is returned instead.

[19 28 XX] (Return One Letter from a Statistic)

Similar to [19 11 XX], this code looks at the value in Secondary Memory, takes the letter in that position of statistic $XX's string, and puts its value into Working Memory. The corresponding values of characters can be found in the Standard Argument Listing. This only works for statistics that are stored internally as strings, not as numbers. A list of all the statistics can be found in the documentation for [1C 01 XX] below.

[1A 00 WW WW WW WW XX XX XX XX YY YY YY YY ZZ ZZ ZZ ZZ AA] (Current Party Member Selection Menu, No Cancel)

[1A 01 WW WW WW WW XX XX XX XX YY YY YY YY ZZ ZZ ZZ ZZ AA] (Current Party Member Selection Menu)

These two codes ([1A 00] and [1A 01]) both display a current party member selection menu. The only difference between them is that [1A 01] allows the player to "cancel" selection with the B button; with [1A 00], the B button does nothing and you must select one of the party members to continue.

The parameters are something of a mystery. The first four appear to be text pointers, but they're not links in a jump table based on which option is selected. In many in-game uses of [1A 01], the first four parameters are all zero! Further experimentation is merited.

The last parameter (AA) appears to control whether or not to display the menu. If it is 1, the menu will be displayed; otherwise, it will not.

1A 04,"UNKNOWN INCOMPLETE";

[1A 05 XX YY] Display the inventory of character YY in window XX.

[1A 06 XX] (Display Shop Menu)

1A 07,"Related to Escargo Express stored goods window";

1A 08,"UNKNOWN INCOMPLETE";

1A 09,"UNKNOWN INCOMPLETE";

[1A 0A] (Open Phone Menu - Dummy?)

1A 0B,"UNKNOWN";

1B - Memory

[1B 00] (Copy Active Memory to Storage)

This code copies the values in all Active Memory to their respective Storage Memory registers. This will overwrite whatever is in Working Memory Storage, Argumentative Memory Storage, and Secondary Memory Storage. The values will remain in the Active Memory registers. This is the most commonly used way to store memory data before using a boolean check or another code that will fill an Active Memory register with its results.

[1B 01] (Copy Storage to Active Memory)

This code copies the values in all Storage Memory to their respective Active Memory registers. This will overwrite whatever is in Active Working Memory, Active Argumentative Memory, and Active Secondary Memory. The values will remain in the Storage Memory registers. This code is often used following a boolean check or other code that manipulates the value in an Active Memory register, when the initial value has been saved using a [1B 00] (Copy All Memory to Storage) code.

[1B 02 XX XX XX XX] (Boolean-False Pointer)

This code checks the value stored in Working Memory. If its value is set to 0x00 (Boolean False), it jumps to pointer $XXXXXX and continues reading from there. If the flag is set to 0x01 (Boolean True), the code does nothing and the engine simply continues past it. Any other value stored in Working Memory will be treated as 0x01 and the code will be summarily ignored. As a jump pointer, it will not return to the location of the original [1B 02 XX XX XX XX] when it reaches a [02] (Stop Parsing) code, it will simply stop parsing.

[1B 03 XX XX XX XX] (Boolean-True Pointer)

This code checks the value stored in Working Memory. If the flag is set to 0x00 (Boolean False), the code does nothing and the engine simply continues past it. If its value is set to 0x01 (Boolean True), it jumps to pointer $XXXXXX and continues reading from there. Any other value stored in Working Memory will be treated as 0x01 and the the engine will successfully jump to the pointer. As a jump pointer, it will not return to the location of the original [1B 02 XX XX XX XX] when it reaches a [02] (Stop Parsing) code, it will simply stop parsing.

[1B 04] (Swap Working and Argumentative Memory)

This code exchanges the values in the Working and Argumentative Memory registers. Whatever is in Working Memory will be placed in Argumentative Memory, and whatever's in Argumentative Memory will be placed in Working Memory. This is useful when you've used a code to generate some value or another, and want to use it in a code that accepts values from Argumentative Memory.

[1B 05] (Copy Active Memory to WRAM)

[1B 06] (Copy WRAM to Active Memory)

1C - Text

[1C 02 XX] (Display Character Name)

This code prints the names of the characters that can join your party in the current window. The value of $XX decides which name to print. [1C 02 XX] uses the Standard Argument Listing for playable characters and NPCs. If $XX is 0x00, the value stored in Argumentary Memory will be used instead of $XX. If $XX is 0xFF, the value stored in Working Memory Storage will be used instead of $XX.

[1C 03 XX] (Display Text Character)

This code prints out text character $XX. In general, this code will always be used with 00 as the argument, loading a previously previously determined value from Argumentary Memory. See [19 11 XX]. If you should ever want to use this code with a constant argument, refer to the Standard Argument Listing for values.

[1C 04] (Open HP/PP Windows)

This code opens the HP/PP status windows at the bottom of the screen. It's often used in cases where either stat is being changed or in the item shop windows. The windows will close when the text block they were opened in stops parsing.

[1C 05 XX] (Display Item Name)

This code prints the name of an item in the current window. The value of $XX is the item number that should be displayed. However, if the value used is 0x00, the engine will instead use the value stored in Argumentary Memory in its place. As there can be over 200 items in EarthBound, it would be inefficient to display all possible arguments here. However, conveniently enough, the Item Editor will display the correct number value next to the item name itself, which should provide as suitable a reference means as any hacker needs.

[1C 06 XX] (Display Teleport Destination Name)

This code prints the name of a destination from the Teleport psychic ability in the current window. The $XX value can be any one of the entries, with values ranging from 0x01 to 0x10. If the value used is 0x00, the engine will instead use the value stored in Argumentary Memory in its place. Any other value will result in a null response. These names can be seen and edited in the Teleport Destination Editor in JHack.

[1C 07 XX] (Display Text Strings Horizontally)

[1C 08 XX] (Display Text Graphics)

This code prints special images, typically seen in battle text, in the current window. There are only two known arguments. An $XX value of 0x01 will display the "SMAAAASH!" graphic, and a value of 0x02 will display the "YOU WON!" graphic. Any other value will result in a null response. [1C 08 XX] does not load values from the Argumentary Memory in the event that the $XX value is 0x00.

1C 09,"UNKNOWN";

[1C 0A XX XX XX XX] (Display Numeric Value)

This code prints the value of $XXXXXXXX as a decimal number in the current window. If the value of $XXXXXXXX is 0x00000000, the engine will instead read the value stored in Argumentary Memory, and display that value as a decimal number.

[1C 0B XX XX XX XX] (Display Numeric Value as Money)

This code prints the value of $XXXXXXXX as a monetary value in the current window. It is formatted like the money values in EarthBound's store windows; the number is aligned to the right side of the window, with a "$" character preceding it and the ".00" character following it. If the value of $XXXXXXXX is 0x00000000, the engine will instead read the value stored in Argumentary Memory, and display that value as a decimal number.

[1C 0C XX] (Display Text Strings Vertically)

[1C 0D] (Display Action User Name)

[1C 0E] (Display Action Target Name)

In a battle action, these codes print the name of the character/enemy doing or receiving the action, respectively. For enemies whose "the" flag is set, the word "the" (capitalized to "The" if the last character printed was a bullet point/@) will be printed before their name.

[1C 0F] (Display Amount of Change)

This code is used to display amount of HP damage/recovery, PP recovery, stat increases at level-up, etc.

[1C 11 XX] (Display Party Description/Zero-Width Space)

In Mother 2, this control code displayed a description of the party (for a party of one, just that person's name; for a party of many, the leader's name + "tachi"). In EarthBound, nothing is printed, but the auto-formatter still thinks something has been printed. Even if it is in the middle of a word, a linebreak may be inserted at the position of this control code. As such, it acts similar to a zero-width space in Unicode. The game uses this code to prevent the extra-long player name from printing incorrectly. No matter which game is used, the argument appears to have no effect.

[1C 12 XX] (Display PSI Name)

[1C 13 XX YY] (Display Battle Animation)

This code will play a PSI animation in combat. XX is used when the ability targets an ally, while YY is used when it targets an enemy. The list of available PSI animations are as follows:

[1C 14 XX] (Load Gender or Number of Action User)

This code loads its result into Working Memory. If the value of XX is 01, it returns the gender of the current action user. If the value of XX is 02 or any other value, it returns the number of living battlers on the user's team (i.e. the number of enemies or the number of living party members).

[1C 15 XX] (Load Gender or Number of Action Target)

This code behaves identically to [1C 14 XX], except that it returns data about the action target and their team.

1D - Inventory and money

[1D 00 XX YY] (Give Item to Character and Return Recipient)

This code will add an item to a character's inventory. The value in $XX stands for the character number, and the $YY value stands for the item number to be added. Nothing will occur if the character does not have any empty slots in his or her inventory. However, if any character recieves the item successfully, the value of Working Memory will also be changed to the number of the character whom recieved the item. This and $XX use the Standard Argument Listing for playable characters and NPCs, and the value of $YY is the item number that will be added. Check the Standard Argument Listing for more details on usage.

[1D 01 XX YY] (Take Item from Character)

This code will remove an item from a character's inventory. The value in $XX stands for the character number, and the $YY value stands for the item number to be removed. $XX uses the standard Argument Listing for playable characters and NPCs, and the value of $YY is the item number that will be added. Nothing will occur if the character does not have the item in his or her inventory. Check the Standard Argument Listing for more details on usage.

[1D 02 XX] (Perform Boolean True Check - Item type)

This code will check the type of the item in the argument registe. 01 checks if the item is can be equipped (weapons, body, arms, others), 02 checks if the item is edible (water, juice, coffee, bread, etc.), 03 checks for usable items (Sale sign,Jeff's items, Horn of Life, etc.), and 00 will check for items not covered in the previous types.

[1D 03 XX] (Perform Boolean True Check - Inventory Vacancy)

This code will check the inventory of the character whose number is equal to $XX. It will then change the value in Working Memory based on the result; Working Memory will be set to 0x00 (Boolean False) if no space remains in the character's inventory, or 0x01 (Boolean True) if empty item slots exist in the inventory. $XX uses the standard Argument Listing for playable characters and NPCs. Check the Standard Argument Listing for more details on usage.

[1D 04 XX YY] (Perform Boolean True Check - Equipped Item)

This code will check if the character XX has item YY equipped. If XX == 0, then the character name will be taken from the rezult register. If YY == 0, the item will be taken from the argument register.

[1D 05 XX YY] (Perform Boolean True Check - Presence of Item)

This code will check the inventory of the character whose number is equal to $XX to see if they are carrying the item whose number is stored in $YY. It will then change the value in Working Memory based on the result; Working Memory will be set to 0x01 (Boolean True) if character $XX has at least one of the item, or 0x00 (Boolean False) if that character does not have the item. $XX uses the standard Argument Listing for playable characters and NPCs. Check the Standard Argument Listing for more details on usage.

[1D 06 XX XX XX XX] (Increase ATM Balance)

This code will increase the balance stored in the ATM by the value of $XXXXXXXX. If the value of $XXXXXXXX is 0x00000000, the engine will instead read the value stored in Argumentary Memory and increase the ATM balance accordingly. The ATM balance can not exceed a value of 9,999,999 (0x98967F).

[1D 07 XX XX XX XX] (Decrease ATM Balance)

This code will decrease the balance stored in the ATM by the value of $XXXXXXXX. If the value of $XXXXXXXX is 0x00000000, the engine will instead read the value stored in Argumentary Memory and decrease the ATM balance accordingly. The ATM balance can not be reduced below 0. That'd just be silly.

[1D 08 XX XX] (Increase Wallet Balance)

This code will increase the balance stored in the Wallet by the value of $XXXX. If the value of $XXXX is 0x0000, the engine will instead read the value stored in Argumentary Memory and increase the Wallet balance accordingly. The Wallet balance can not exceed a value of 99,999 (0x01869F).

[1D 09 XX XX] (Decrease Wallet Balance)

This code will decrease the balance stored in the Wallet by the value of $XXXX. If the value of $XXXX is 0x0000, the engine will instead read the value stored in Argumentary Memory and decrease the Wallet balance accordingly. The Wallet balance can not be reduced below 0. That'd just be silly.

[1D 0A XX] (Return Price of Item)

This code will change the value stored in Working Memory to match the price of the item whose number is stored in $XX. To use this returned information you will likely have to transfer it to Argumentary Memory, using [1B 04] (Swap Working and Argumentative Memory) or [0D XX] (Copy to Argumentative Memory). See those codes' entries for more information.

[1D 0B XX] (Return Selling Price of Item)

This code will change the value stored in Working Memory to match one half of the price of the item whose number is stored in $XX. To use this returned information you will likely have to transfer it to Argumentary Memory, using [1B 04] (Swap Working and Argumentative Memory) or [0D XX] (Copy to Argumentative Memory). See those codes' entries for more information.

[1D 0C XX XX] (Check If Item Can Be Stored By Escargo Express)

This code checks the $YYth item in character $XX's inventory. If an item is okay to store and Escargo Express's item storage has room, the code returns 0. If an item is not okay to store but Escargo Express's item storage has room, the code returns 1. If an item is okay to store but Escargo Express's item storage is full, the code returns 2. If an item is not okay to store and Escargo Express's item storage also is full, the code returns 3.

[1D 0D XX YY YY] (Check for Status Ailment)

[1D 0E XX YY] (Give Item to Character, Return Recipient and Number of Items)

This code will add an item to a character's inventory. The value in $XX stands for the character number, and the $YY value stands for the item number to be added. Nothing will occur if the character does not have any empty slots in his or her inventory. However, if any character receives the item successfully, the value of Argumentative Memory will also be changed to the number of items they have in their inventory (including the new one). Additionally, the value of Working memory will be changed to the number of the character whom recieved the item $XX uses the standard Argument Listing for playable characters and NPCs, and the value of $YY is the item number that will be added. Check the Standard Argument Listing for more details on usage.

[1D 0F XX YY] (Remove Character XX's YYth Inventory Item)

This code removes the item belonging to the specified character in the specified inventory slot. After removing the item, working memory is set to the ID of the character from which the item was removed, and argumentary memory is set to the ID of the item that was removed. This makes it easy to add the item back via 1D 0E above. If $XX is 0, working memory is used instead of $XX. If $YY is 0, argumentary memory is used instead of $YY.

[1D 10 XX YY] (Perform Boolean True Check - Item in Slot Equipped)

This code checks if the item in Slot YY of Character XX's INVENTORY is equipped. That is, YY is not looking at equipment slots, it's looking at the particular item in that position in the character's inventory.

[1D 11 XX YY] (Equippable check)

YY is item slot number, while XX is the character to check if the equipment is valid for.

1D 12 XX XX,"UNKNOWN"; (Used by Tracy when giving her an item.)

1D 13 XX XX,"UNKNOWN"; (Used by Tracy when retrieving an item from her.)

[1D 14 XX XX XX XX] (Check for Cash on Hand) *True if X<$

[1D 15 XX XX] (Input numerical value into Argumentary Memory)

This code is often use right before a hotel keeper would welcome you to his hotel and then tell you the price of a room for the night. This allows use of [1C 0A 00 00 00 00] in 1 text line to cover all hotels in the game.

[1D 17 XX XX XX XX] (Check for Cash in ATM)

[1D 18 XX] (Add Item to Escargo Express)

This code adds the item XX to the Escargo Express' inventory. XX being the hex ID value of the item.

• 01: Plays the coffee scene from Saturn Valley.
• 02: Plays the tea scene from Tenda Village.
• 03: Opens the menu for entering the player's name in Summers and sets working memory.
• 04: Originally opened the menu for entering the player's name in Japanese in Tenda Village. This code was only used in Mother 2, not in EarthBound, but it remainds functional and uses an English keyboard.
• 05: Sets the "overworld status suppression" (OSS) flag, preventing the player from taking damage on the overworld even if they are underwater or have a status that deals damage over time.
• 06: Clears the "overworld status suppression" (OSS) flag, allowing the player to take damage on the overworld again. If flag 49 00 (in CCScript dumps, flag 73) is set, this instead sets the OSS flag as if 05 were used.
• 07: Opens a view of the town map for the current area, if a map exists. Working memory is set to the ID of the town map that is displayed, or 0 if the current area does not have a town map.

• 09: Shows the normal sound stone screen that can be canceled by pressing a button.
• 0A: Shows a still image of the title screen that fades away when the player presses a button.
• 0B: Shows the "Cast" scene that plays during the first part of the ending.
• 0C: Shows the "Credits" scene with the names of the developers and the photos taken by the photo man.
• 0D: Causes all HP and PP meters to begin scrolling randomly, as when Ness powers up at the end of Magicant.
• 0E: Resets the effect caused by 0D.
• 0F: Clears all event flags in the game.
• 10: Shows the final sound stone screen that cannot be canceled early.
• 11: Attempts to inflict homesickness on Ness based on his level. Sets working memory to 1 if Ness became homesick, otherwise 0.
• 12: Kicks Ness out of bicycle mode if he is currently in it. Sets working memory to 1 if Ness was just on a bicycle, otherwise 0.

Unless stated otherwise, this code sets working memory to 0.

[1F 50] (Disable Controller Input)

[1F 51] (Enable Controller Input)

[1F 52 XX] (Generate Number Selector)

This code creates a menu in the current window allowing the user to input a number. $XX is the number of digits the number can have. If the user cancels the menu with the B button, working memory and argumentary memory are both set to 0; otherwise, working memory is set to the number the user chooses and argumentary memory is not modified.
