Entry

Entries are the intermediate level data containers in NSF files. They are containers for 'items'-the lowest level data containers in NSF files.

Types
An entry's type determines the specific kind of content contained in its items. 1 - NSD files may contain these kinds of entries, but without any header.

Entry IDs/EIDs
Like chunks, each entry has also been assigned a unique ID. Unlike CIDs, however, entry IDs (EIDs) have not been precomputed based on index. Each EID encodes a unique 5 character identifier string. Each entry has been assigned an EID that encodes an appropriate identifier.

Encoding scheme
EIDs use the following [32 bit] encoding scheme:

0EEEEEEDDDDDDCCCCCCBBBBBBAAAAAA1

where the [6 bit] fields A, B, C, D, and E, respectively, in that order, are indices of 5 characters in the following conversion table:

The conversion table above is used by the EID encoding and decoding routines and is located at the following addresses in each of the Crash games:
 * Crash 1 -

Null EID
The EID with value, which translates to  , is used frequently throughout the game code. It represents a null EID.
