LEV
- Format Type : Encrypted Text (XML)
- Endian Order : Little Endian
- Signature : JC
Format Specifications
// LEV file format (after decrypting) // header 2 bytes (char) - signature // "JC" 4 bytes (uint32) - decompressed data size // data x bytes - data compressed with JCALG1 algorithm
Notes and Comments
- LEV files occur in some Retro64 games.
- LEV files are usually compressed and encrypted XML files.
- LEV files may be encrypted with Bitwise NOT operation.
- LEV files may be compressed with JCALG / JCALG1 compression method (Algorithm is slightly modified in the Retro64 version - there is no checksum field in the header, so it needs to be added manually as "0" checksum to skip checksum validation and decompress data correctly).
