PACK
- Format type: Archive
- Endianness: Little-endian
Format Specifications
byte {X} - LZMA decoder properties bytes (typically 5 bytes)
uint32 {4} - File count- char {X} - File name (.NET style string with size byte followed by characters)
- int64 {8} - File length
- int64 {8} - Compressed length
- int64 {8} - File content offset
- uint16 {2} - Attributes and flags (0: Uncompressed, 1: Compressed)
Programmatic Extraction
You can use the game engine itself to extract files. From one of the games listed below, obtain either LuckySoftCore.dll or Engine.dll (name depends on game) and reference it in your .NET code. The following shows how to call the engine function to obtain a handle to the LzmaPack.
using EngineBase; //using LuckySoftCore; using EngineBase.Core; // using LuckySoftCore.Core; using EngineBase.Compression; // using LuckySoftCore.Compression; IDirectoryInfo repo = LzmaPack.OpenLZMAPack(strPathToLzmaPack);
IDirectoryInfo is similar to System.IO.DirectoryInfo, except it allows arbitrary underlying implementations, so you could read files from e.g. LzmaPacks.
Notes and Comments
Archive files of this format out in the wild is encrypted with an XOR stream cipher based on an Mersenne Twister implementation. You can find a Stream class for decryption in the Engine named GammaXoringStream.
MultiEx BMS Script
Note: not working. Decoder properties are stored once at the beginning of the archive instead of in each file.
