 # NODENAMELIST
 
+## NNE_NODENAME_SORTTYPE
+
+!!! note
+    The underlying type of this enum is not specified, thus it
+    may differ depending on the platform. In practice, it's always
+    an `int32_t` in all known NN games.
+
+This enum indicates the way the [NNS_NODENAME](#NNS_NODENAME) structs are sorted in the `pNodeNameList` array used in the [NNS_NODENAMELIST](#NNS_NODENAMELIST).
+
+```c
+enum NNE_NODENAME_SORTTYPE
+{
+    // The NNS_NODENAME structs are sorted by their
+    // [iNode] index field, from least to greatest.
+    NNE_NODENAME_SORTTYPE_INDEX,
+
+    // The NNS_NODENAME structs are sorted by their
+    // [Name] field, ordered as if by C's strcmp.
+    NNE_NODENAME_SORTTYPE_NAME
+};
+```
+
 ## NNS_NODENAMELIST
 
 !!! important
-    This is the "main" (root) struct for all NN node (bone) name list chunks.
+    This is the root struct for all NODENAMELIST data chunks.
+
+A list of the names for the nodes (bones) that make up an object (model).
 
 ```c
 struct NNS_NODENAMELIST
 {
-    /* The sorting type */
+    // The way the NNS_NODENAME structs in
+    // the [pNodeNameList] array are sorted.
     NNE_NODENAME_SORTTYPE SortType;
 
-    /* The size of [pNodeNameList] array */
-    uint32_t nNode;
+    // The number of elements in the [pNodeNameList] array.
+    int32_t nNode;
 
-    /* An array of NNS_NODENAME structs */ 
+    // An array of NNS_NODENAME structs.
     NNS_NODENAME* pNodeNameList;
 };
 
-/* Macros used by Text-Form files: */
-#define	NODENAMELIST( SortType, nNode, pNodeNameList ) { SortType, nNode, pNodeNameList }
+// Macros used by Text-Form files:
+#define NODENAMELIST(SortType, nNode, pNodeNameList) { SortType, nNode, pNodeNameList }
+#define NDNL_TYPE(SortType) (SortType)
+#define NDNL_N_NODE(nNode) (nNode)
+#define NDNL_NAMELIST(pNodeNameList) (pNodeNameList)
 ```
 
 ## NNS_NODENAME
 
-The actual node (bone) name
+A name for a single node (bone).
 
 ```c
 struct NNS_NODENAME
 {
-    /* The node index */
-    uint32_t iNode;
+    // The index of the node, in the [pNodeList]
+    // array in the corresponding NNS_OBJECT.
+    int32_t iNode;
 
-    /* The node name */
-    char* Name;
+    // The name of the node.
+    const char* Name;
 };
 
-/* Macros used by Text-Form files: */
-#define	NODENAME( iNode, Name ) { iNode, Name }
+// Macros used by Text-Form files:
+#define NODENAME(iNode, Name) { iNode, Name }
+#define NDNM_IDX(iNode) (iNode)
+#define NDNM_NAME(Name) (Name)
 ```

-## NNE_NODENAME_SORTTYPE
-
-This enum indicates the sorting type used in the node name list.
-
-```c
-enum NNE_NODENAME_SORTTYPE
-{
-    /* Sorting by index */
-    NNE_NODENAME_SORTTYPE_INDEX,
-
-    /* Sorting by name */ 
-    NNE_NODENAME_SORTTYPE_NAME
