A collection of resources for working with params via SoulsFormats and SoulsFormats-derived tools.
Three folders are included for each game:
- Defs - paramdefs required to edit param data, given in XML format. Filenames are arbitrary; apply based on the included metadata after loading.
- Names - predefined row names, primarily for newer games with names stripped. Names should not be assumed to be present for every param.
- Tdfs - paramtdfs provide friendly names for enumerated types. Only officially shipped with Demon's Souls. Additionally, for ACVI some param files are mangled and do not include the param type string; ParamTypes.txt includes the correct param types for those that need it.
Paramdefs for DeS, DS1, and BB were shipped with the games and should not be altered beyond translating display names and descriptions.
Paramdefs for SDT, ER, and ACVI are mostly official but have been extended slightly due to updates. The above applies to any original fields.
Paramdefs for other games were reverse-engineered, so improvements are welcome.
| Game | Directory |
|---|---|
| Dark Souls | DS1 |
| Dark Souls: Remastered | DS1R |
| Dark Souls II: Scholar of the First Sin | DS2S |
| Dark Souls III | DS3 |
| Demon's Souls | DES |
| Bloodborne | BB |
| Sekiro | SDT |
| Elden Ring | ER |
| Armored Core VI | AC6 |
All paramdefs should contain the following elements:
| Element | Description |
|---|---|
| ParamType | Correlates the paramdef to its params |
| DataVersion | Indicates a revision of the param data structure |
| BigEndian | Whether the binary format is big-endian |
| Unicode | Whether description strings are encoded in UTF-16 |
| FormatVersion | Determines the binary format of the paramdef |
| Fields | Contains the Field elements that describe param data |
Each Field element has a mandatory Def attribute that specifies the type, internal name, bit size or array length if needed, and (optionally) default value. Bit size and array length are written as in a C declaration.
<!-- Minimum required info -->
<Field Def="u16 iconId" />
<!-- Specifying a default value -->
<Field Def="u16 iconId = 1000" />
<!-- Defining a bitfield -->
<Field Def="u8 enableGuard:1" />
<!-- Defining an array -->
<Field Def="dummy8 padding[2]" />Additionally, the following elements may be added to customize editor functionality:
| Element | Description |
|---|---|
| DisplayName | A more human-readable name for the field |
| Enum | Indicates an enumerated type; corresponds to a paramtdf |
| Description | A description of the field's purpose |
| DisplayFormat | A printf format string for displaying the value |
| EditFlags | Controls editor behavior; known flags are Wrap and Lock |
| Minimum | The minimum acceptable value |
| Maximum | The maximum acceptable value |
| Increment | How much to increase or decrease the value per step |
| SortID | An arbitrary number that determines display ordering of fields |
| UnkB8 | An optional new string of unknown purpose; appears to be an identifier. |
| UnkC0 | An optional new string of unknown purpose; appears to be a param type. |
| UnkC8 | An optional new string of unknown purpose; appears to be a display string. |
Any elements not provided will be given sensible default values based on the field's type. Default, Minimum, Maximum, and Increment are always specified as floats, so they are not meaningful for array types.
<!-- A fully-loaded declaration -->
<Field Def="u32 foobarType:7 = 15">
<DisplayName>Foobar Type</DisplayName>
<Enum>FOOBAR_TYPE</Enum>
<Description>Determines the foobarosity of the whizbang.</Description>
<DisplayFormat>%8x</DisplayFormat>
<EditFlags>Wrap</EditFlags>
<Minimum>10</Minimum>
<Maximum>100</Maximum>
<Increment>5</Increment>
<SortID>1500</SortID>
</Field>All available types are listed below.
