## Specifications and Info
<sup>Bytes are in Little Endian</sup>
Each CZ file starts with a header.
Each `CZ#` file starts with a header. The first 14 (`0x0E`) bytes of the header are common to all
`CZ#` files. The data which come after that are specific to each format, although several
`CZ#` formats do share the same layout.
### The CZ0 and CZ3 header:
### Common header:
| Offset | Ex. Values | ASCII | Purpose |
