Menu and UI text (BmGame\Localization\<LANG>\*.<lang>)

The menus, HUD, character bios, riddles, credits and other UI strings are UE3 localization files, one folder per language (INT, ITA, FRA, DEU, ESN, ESM, POL, POR, RUS, JPN, KOR), ~37 files and ~7,000 strings each (FRONTEND, GFxUI, Bios, Credits, PC, RIDDLER, ...). ackit reads and writes them with ackit/loctext.py through Workspace.texts.

Format

• UTF-16LE with a BOM (FF FE), CRLF line ends; the first line is empty. (INT\Version.int and VersionData.int are plain ASCII build IDs, not UI text: ackit ignores them.)
• [Section] lines, Key=Value lines, ; comments. A few values are in double quotes (Quit="Quit game").
• File extension = language code (FRONTEND.int, FRONTEND.FRA); case varies, lookups are case-insensitive.
• Markers inside values (e.g. \n, button tags) are the game's own; ackit keeps them as plain text.

Keys and writing

• Key: MENU:<LANG>:<File>:<Section>:<Key> (#n for a repeated key; none in the shipped files).
• Writing replaces only the value part of the edited lines (quotes kept); BOM, encoding, other lines and line ends stay byte-identical. Values cannot contain line breaks; characters must fit the file's encoding.
• The files are rebuilt from the store's original copy + the applied edits, so reverting restores them exactly.
