Scarlet

Scarlet and its related libraries are aiming to provide functionality to convert, export and import various types of game data. They are written in C# and based on the .NET Framework.

Disclaimer

This project is still incomplete and work-in-progress. Functionality will change, be added or removed, and all interfaces, calling conventions, etc. should be considered subject to change.

Requirements

• General
  • .NET Framework 4
• Compilation
  • Visual Studio Community 2013 (or higher)

Parts

• Scarlet: Common main library (required)
• Scarlet.IO.ImageFormats: Library for image file format conversion (requires Scarlet)
• Scarlet.IO.ContainerFormats: Library for container/archive management (requires Scarlet)
• Scarlet.IO.CompressionFormats: Library for handling compressed data (requires Scarlet)
• ScarletTestApp (ScarletConvert): Sample converter application implementation (requires all the above)

  • TMX (various Atlus games)
  • TX2 (ex. Phantom Brave, PS2 version, various other Nippon Ichi Software games)
  • TXF (ex. Disgaea 4, PS3 version, possibly more Nippon Ichi Software games)
  • TXG (ex. Sakurasou no Pet na Kanojo, PSP version)
    • XGTL (wrapper around multiple TXGs)
      • CBG (wrapper around XGTL)
  • TXP (ex. Z.H.P: Unlosing Ranger vs Darkdeath Evilman, Disgaea 2 PSP, Disgaea Infinite, possibly more Nippon Ichi Software games on PSP)
  • VTXP (ex. Punchline, PS Vita; not the same as, nor related to TXP above)
• Containers
  • FADEBABE (ex. Akiba's Trip, original PSP version, namely DATA1.DAT)
  • FMDX (ex. K-ON! Houkago Live, PSP version)
  • GAR v2 and v5 (ex. The Legend of Zelda: Majora's Mask 3D, Ever Oasis)
  • NISPACK (various Nippon Ichi Software games)
  • NSAC (ex. Disgaea 4, PS Vita version, possibly more Nippon Ichi Software games)
  • PSPFS_V1 (ex. Phantom Brave, PSP version, possibly more Nippon Ichi Software games)
  • Stellvia DATs (Uchuu no Stellvia, PS2 version)
  • UKArc/PAC (ex. Dengeki Bunko: Fighting Climax, PS Vita version)
  • ZAR v1 (ex. The Legend of Zelda: Ocarina of Time 3D)
• Compression
  • DR 1/2/AE (Danganronpa 1, 2 and Another Episode, PS Vita)
  • Grezzo LzS (ex. The Legend of Zelda: Majora's Mask 3D)
  • GZip (generic; also ex. Dengeki Bunko: Fighting Climax, PS Vita version)
  • NIS LZS (ex. Disgaea 4, PS3 and PS Vita versions)
  • Nintendo DS LZSS-0x10 (generic; also ex. Shin Megami Tensei: Devil Survivor Overclocked)

Note that support for these is not 100% complete (especially Capcom TEX is lacking), as well as the unintentional bias towards NIS games.

Usage

Sample Converter

Syntax: ScarletTestApp.exe <inputs ...> [options]

• <inputs ...>: Any number of files or directories to be converted, separated by spaces
• [options]:
  • --output | -o: Specify output directory
  • --keep | -k: Do not overwrite existing output files

Example: ScarletTestApp.exe "C:\Temp\files\" "C:\Temp\testfile.gxt" "C:\Temp\testfile2.nmt" --output "C:\Temp\output\"
