TTG Font Creator

TTG Font Creator is a specialized font editor for Telltale Games, designed to create, modify, and fine-tune .font files used across multiple platforms including Nintendo Switch, PC, PS3, PS4, PS Vita, Xbox 360, Wii, iOS and Android.

Re-designed and re-implemented Font Editor, originally based on TTG Tools by Den Em and Pashok6798.

Why TTG Font Creator

Telltale's .font binary format (5VSM/6VSM/ERTM) stores glyph textures, character metrics, and layout parameters in a platform-specific structure. Creating compatible fonts for fan translations or modding requires precise control over:

• BMFont → .font conversion: Import .fnt files and associated DDS textures, with automatic platform detection and swizzle settings
• FNT header parameters: info size (point size), common lineHeight (line spacing), common base (baseline / vertical text position) — all preserved and editable through the FNT Adjust panel
• Texture pipeline: Multi-page DDS (BC3/DXT5) support, platform-specific texture headers (block layouts, swizzle flags), ObjectName/SubObjectName generation
• Character metrics: Per-glyph X/Y offsets, advance widths, UV coordinates, channel assignments — batch-adjustable via the FNT Adjust panel
• Chinese / CJK support: Full UTF-8 encoding for FontName and ObjectName — Chinese font names (e.g. 思源黑体 Heavy) survive save/reopen round-trips
• Create fonts from scratch: New → Import FNT → Import DDS → Save — build a complete, game-ready .font file with no existing source required, generating all texture headers, element tables, and platform-specific metadata automatically
• Text-centric workflow: Designed around a complete fan translation pipeline — Unpack archives (ttarch/ttarch2) → Develop fonts (create, import, adjust, save) + Normalize landb text (CJK spacing, punctuation, line-break fixes) → Pack back into archives. Every tool in the Tools menu is organized to serve this workflow.

Recent Changes

Archive Unpacker Improvements (2026-04)

• Ttarch2 Scanner: New tool for scanning ttarch2 archives — browse file listings without full extraction
• Oodle Kraken Support: Added detection and decompression for Oodle Kraken (0x8C 0x06) algorithm, previously only LZHLW was supported
• Last Chunk Padding Detection: Combined approach — try full chunkSize first (padded archives), fall back to file offset calculation (unpadded archives). Displays padding status in Archive Info panel
• Archive Info Panel: Now shows compression algorithm name (Deflate / Oodle LZHLW / Oodle Kraken), TTArch2 version (3ATT/4ATT), and last chunk padding status
• Cross-Thread Fix: Fixed InvalidOperationException when extracting files with search filter or format filter enabled
• Lua Encryption Detection: Improved — only marks .lenc files as encrypted by default, checks .lua files by reading actual content after decompression

Font Editor Enhancements (2026)

• YOffset Batch Adjustment: Added "FNT Adjust" groupBox with YOffset adjustment controls — apply a delta value (e.g., +3 or -5) to all characters' YOffset at once, instead of per-character
• Switch Font Compatibility Fix: Fixed two critical bugs that prevented NewFormat fonts from displaying on Nintendo Switch:
  • FontName overwrite: FNT import no longer overwrites an existing FontName — only updates when the name is empty or the default NewFont. Prevents glyph block misalignment caused by name length mismatch.
  • Header offset 0x08: Always written as 0 (structural separator). Was incorrectly written as the real texture count, corrupting the file header and causing Switch to reject the font.
• New Font Workflow: New → Import FNT → Import DDS → Save now produces a fully compatible NewFormat font for Nintendo Switch (platform=15, BC3/DXT5, multi-page supported)
  • Switch Hardware Layout Block: EnsureNewTextureHeaderDefaults() now injects the 60-byte hardware texture parameter block (tex.block) when it is uninitialized. Without this block, the game crashes with colorful texture artifacts because the Switch GPU cannot parse the texture memory layout. The template is derived from official Switch fonts and contains tile mode, format, and memory layout parameters required by the hardware decoder.
• UI Optimization: Improved user interface with better layout and usability
• Font Detection: Added automatic font detection capability for easier file handling
• Missing Character Generation: Implemented automatic generation of missing characters for comprehensive font support
• Texture Management: Enhanced DDS texture file handling with automatic copying during save operations
• Multi-page Support: Improved support for fonts with multiple texture pages
• Default Font Fix: Set default font to Tahoma to prevent layout issues on non-English systems
• Profile System: Save/load Y offset, Font Size adj, font family, font style, and font file path settings
• Font Picker Dialog: Redesigned as a VS-designable Form — supports system font search filter, style selection (Regular/Bold/Italic/BoldItalic), and TTF/OTF file browsing
• CJK Font Fallback: Font picker automatically uses a CJK-capable font (Microsoft YaHei, Yu Gothic, Meiryo, etc.) for correct display of all font names on any locale
• Smart Gap-Filling: Detects empty slots on the last texture page via FNT table lookup + pixel verification, fills them before creating new pages
• Regeneration: Re-generate with different settings (Y offset, font size) by reusing the same page positions and restoring original page data

Archive Packer Improvements (2026)

• Padding Control: Added option to control last chunk padding (compatible mode pads to full chunk size)
• Oodle Compression: Corrected function signature (10 parameters + StdCall) for OodleLZ_Compress
• Header Accuracy: Fixed zCTT header field ordering and chunksFirstOffset calculation for Oodle compressed archives
• Kraken Buffer Overflow Fix: Fixed delayed AccessViolation crash when compressing large dense binary files (.font, .d3dtx) with Oodle Kraken — output buffer now includes extra padding to prevent native heap corruption

Text Normalization Improvements (2026)

• Remove blanks between CJK characters: Added an AutoPacker option to remove unnecessary spacing between CJK characters during import, preserving natural CJK text flow.
• Dot-to-Chinese-period replacement: Added support for converting ASCII dots near CJK text into full-width Chinese periods during import, improving punctuation consistency in localized dialogue.
• Newline punctuation normalization: Added AutoPacker Text Normal option to normalize punctuation before explicit \n markers during import, preventing malformed line breaks like \n。 and preserving proper sentence structure. This option is enabled by default.
