Format Specifications

// Header data

uint32 {5} - Unknown1

char {1} - Unknown2

byte {x} - Top level directory filename (null padded)

uint32 {1} - Absolute offset to subdirectory data (value read here must be multiplied by 8)

uint32 {1} - Length in bytes of subdirectory data

byte {x} - Subdirectory filename (null padded)

// Subdirectory data

uint32 {5} - Number of files

// For each file

uint32 {1} - Absolute offset to file data (value read here must be multiplied by 8)

uint32 {1} - Length in bytes of file data

byte {x} - Filename (null padded)

// File data

uint16 {1} - Relative offset to file content

uint16 {1} - Number of keys used for decryption

uint32 {1} - Length in bytes of file content (length of decompressed file if compression is set)

char {8} - XOR encrypted string Null padded string. The latest byte is the value to use to 'decrypt' the other bytes of this string using XOR. The string is either "NotComp\0" (non compressed file) or "Hi_Comp\0" (compressed file).

// Decryption data

uint32 {number of keys} - Start value for decryption

uint32 {number of keys} - Length in bytes of a file block on which to apply decryption

byte {x} - Crypted and compressed file content To read the file content, decryption must be performed first (always), then decompression (optional, only if the above string is set to "Hi_Comp\0").
