What follows is a non-exhaustive list of common definitions used by the Sega NN Chunk Format.

== NNS_VECTOR ==
Represents a Vector3.<syntaxhighlight lang="cpp">
struct NNS_VECTOR

float x;
float y;
float z;
};
</syntaxhighlight>

== NNS_VECTOR2D ==
Represents a Vector2.<syntaxhighlight lang="cpp">
struct NNS_VECTOR2D
{

float y;
};
</syntaxhighlight>

== NNS_RGB ==
Represents an RGB color value.<syntaxhighlight lang="cpp">
struct NNS_RGB
{
float r;

};
</syntaxhighlight>

== NNS_TEXCOORD ==
Represents a two-dimensional UV texture coordinate.<syntaxhighlight lang="cpp">
struct NNS_TEXCOORD
