Format Specifications
// Crazy Racing PAK file format (by barncastle)
struct Archive
{
uint FileCount;
FileInfo FileInfos[FileCount];
byte Data[x];
}
struct FileInfo
{
uint Hash;
int Offset; // multiply by 4
int CompressedSize; // LZMA
}
Hash Algorithm
uint Hash(string value)
{
// append suffix and lowercase
// e.g. Res\ALight.mesh => res\res\alight.mesh
value = (@"res\" + value).ToLower();
uint h = 0u;
for (int i = 0; i < value.Length; i++)
h = 31 * h + (byte)value[i];
return h;
}
