Following is a table that describes which languages appear in the file.

=== String Names ===
Possible language codes:


In Echoes, strings can have names attached to them. Note that this table only appears in the Echoes STRG format; for Prime 1, skip ahead to the string tables.
{| class="wikitable"
! ID
! Language
|-
| <code>ENGL</code>
| English
|-
| <code>FREN</code>
| French
|-
| <code>GERM</code>
| German
|-
| <code>SPAN</code>
| Spanish
|-
| <code>ITAL</code>
| Italian
|-
| <code>DUTC</code>
| Dutch
|-
| <code>JAPN</code>
| Japanese
|}
 
Note that while Dutch doesn't actually appear in any STRG files, the fourCC for it can be found in the dol alongside the other language codes, so the game probably supports it.
 
=== Name Table ===
 
In Echoes, this table is used to attach a name to the strings in the file. The names are used internally to allow the game to look up a particular string from a file using its name rather than having to hardcode a string index to find it. This table only appears in the Echoes STRG format; for Prime 1, skip ahead to the string tables.

| u32
| '''Name count'''
| 1
| '''Name Count'''
| Number of string names in the table. Note this does not necessarily equal the regular string count! It's possible to have a STRG file where some strings have names and some don't.

|-

| 0x8
| 0x8
| colspan=2 {{unknown|Name entries begin}}
| [[#Name Entry|Name Entry]]
| ''Name Count''
| '''String Name Entries'''
| This array doesn't contain the names themselves, but it defines each one and associates it with one of the strings.
|-
| {{none}}
| string
| ''Name Count''
| '''String Name Array'''
| This is an array of zero-terminated ASCII strings. The names are sorted in alphabetical order; the sorting is case-sensitive, so 'Z' will appear before 'a'.
|-
| colspan=5 {{unknown|End of name table}}
|}
|}


Each entry is structured as follows:
==== Name Entry ====
 
This structure is used to point to a name in the ''String Name Array and associate it with one of the strings from the file.

|-
|-
| 0x8
| 0x8
| colspan=2 {{unknown|End of entry}}
| colspan=5 {{unknown|End of entry}}
|}
|}


After every name entry comes all the names in the form of a large UTF-8 string array. The names are zero-terminated, and they're sorted in alphabetical order; the sorting is case-sensitive, so 'Z' will appear before 'a'.
=== String Table ===
 
=== String Tables ===


Last are the actual string tables themselves. Each table contains some metadata followed by a series of UTF-16 strings. The number of strings is declared in the header; there will be one of these tables present per language present in the file.
The file contains one string table per language. Each table contains some metadata followed by a series of UTF-16 strings. The number of strings included in each table is determined by the ''String Count'' value in the header, which is consistent across every language in the file.
