The '''STRG format''' in Metroid Prime 3 is another update to the STRG format, used both in Prime 3 as well as Donkey Kong Country Returns. The most significant change from the Echoes STRG format is that the string encoding was changed from UTF-16 to UTF-8. There was also a more robust system for string offsets implemented, allowing for the same string of text to be reused for multiple languages if the string is identical in both.
The '''STRG format''' in Metroid Prime 3 is another update to the STRG format, used both in Prime 3 as well as Donkey Kong Country Returns; the only difference between the two is that DKCR supports more languages. The most significant change from the Echoes STRG format is that the string encoding was changed from UTF-16 to UTF-8. There was also a more robust system for string offsets implemented, allowing for the same string of text to be reused for multiple languages if the string is identical in both.

The header should be familiar to you if you've worked with the Prime 1/2 STRG format in the past. It remains unchanged.
The initial header is identical to Prime 1/2. The differences start after that; the name table now precedes the language table, and the language tables and string tables are structured differently.

=== String Names ===
Possible language codes:
 
The next part of the file is a table that allows names to be assigned to strings. It's identical to the name table structure from Echoes.

Each entry is structured as follows:
Notes:
* In DKCR, Japanese appears after English instead of after Italian.
* The languages <code>DUTC</code>, <code>SCHN</code>, and <code>TCHN</code> are unused and don't actually appear in any STRG file. However, their fourCCs can be found in the dol alongside the other language codes, so presumably the game supports them.
 
=== Name Table ===
 
This part of the file is a table that allows names to be assigned to strings. It's identical to the structure from Echoes, so check [[STRG (Metroid Prime)#Name Table|the Echoes documentation]] for details.
 
=== Language ===
 
This is a small structure that defines where the strings for a particular language are located. It appears once per language.

| '''Strings Size'''

| 0x4

| u32
| '''String index''' - this is the string number that the name is associated with
| ''String Count''

| Relative to the start of the first string.
|-
|-
| 0x8
| colspan=5 {{unknown|End of language definition}}
| colspan=2 {{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 ===
 
=== Languages ===
 
Next is a segment that defines which languages are included by the file and where their strings are. This section of the file starts with one fourCC for each supported language. Then this small structure repeats per language:


{| class="wikitable"

| Size of the string data in bytes.

| 0x4

| u32[]
| string
| 4 &times; string count
| '''String'''
| '''String offsets'''; relative to the start of the first string
| Zero-terminated string encoded with UTF-8 Unicode.
|-
| colspan=4 {{unknown|End of string}}
|}
|}
=== Strings ===
Finally, the actual string data. Each string is composed of a 32-bit size followed by UTF-8 Unicode string data.
