This page is a list of Conds (Conditions), where they are found along with format documentation aka what they are (Yo-kai Watch Conds DO NOT always work across games i.e. Yo-kai Watch 3 - although they may. Please test this yourself).

Documented Useful Conds List

Note: Some conds are customisable, in that case the raw bytes will be linked, use a website like this to convert it to base64.
0 - Always True / Null Cond. (Global)
- 1 - Used in place of a Cond in certain situations. (Yo-kai Watch 2)

Conds Documentation/Specification

1. Cond Description

A Cond is a little-endian binary structure representing a boolean condition in Yo-kai Watch games. It can check things like flag states, inventory items, watch rank, or story progress.

Note: For the sake of simplicity and ease of access the hex here will be big-endian. The linked tool handles this appropriately.
Stored as a Base64 string in cfg.bins. Convert to hex before handling.
Can include nested or extended parameter blocks.
Always ends with a terminator (0x78 or 0x71)??.
All types are implicit: 00 00 00 01 could mean 1, true, the “SOH” character, or the equivalent float.

2. Basic Cond Layout

Note: Examples are at the end.

[HEADER 4B]
[OPCODE 2B]
35                    ; Section Start
[RESOURCE ID 4B]      ; ???
[EXTENSION CTYPE]            ; Usually 3B: 00 01 00 (or 00 0D 0A 01 for extended due to null padding)
[EXTENSION DELIMITER]  ; 28 (optional, separates extension header from parameters)
[CTYPE 3B]             ; Comparison type / selector
32                     ; Section End
[COMPARISON VALUE 4B]  ; Value to compare in hex (e.g., 0x00000001 = true, 1, "SOH" or the equivalent float).
[TERMINATOR 1B]        ; End of cond

3. Headers and Opcodes

Field	Example	Meaning (Theorized)
HEADER	`00 00 00 00`	Reserved / start of Cond
OPCODE	`0F 05`	Compare >= (constant comparison)?
OPCODE	`18 05`	Flag comparison maybe >=??

4. Sections and Delimiters

Byte	Meaning
`35`	Section Start / block delimiter
`32`	Section End / block terminator
`28`	Extension delimiter?? (separates extension header from sub-params)
`34`	Nest delimiter??

Multiple 35 markers can represent nested sections, being often used in more complex conds like flag state checks.

5. CType

Usually starts as 00 01 00 for a simple check.
Extended mode uses 00 0A 01 - adding a 3rd seems to pad a 00 (null termination) for unknown reasons:
- Proven by a weird variant which uses 00 0D 0A 01:
- First byte (0D) = extended flags count / special mode???????
- Second byte (0A) = AND / OR / combinator (most likely)
- Third byte (01) = standard
Flags may be added together bitwise to construct the final check value - but this is weird and iffy.
Flag checks usually use the Ctype: 00 06 02

6. Resource IDs

Resource ID = 4 bytes identifying something.
Example: A1 7D 35 34

Note: 34……

7. Comparison Value

Always 4 bytes after the final section ends (32).
Indicates the value to compare against.
- 00 00 00 01 -> 0x00000001 aka 1 or true.
- Another example is 00 00 00 05 aka 5 or Watch Rank S.

8. Terminator

Usually 0x78 or 0x71.
Marks the end of the Cond.

Examples:

Basic Conds:
- Watch Rank >= XX (YW2) Cond:
