'''Yaz0''' is the encryption format used by both Galaxy 1 and 2. Almost every game that has used the encryption stores the file in a szs extension

Below you'll find helpful tables on how the file is structured
== Header ==
{| class="wikitable"
! Offset !! Type !! Description
|-
| 0x00 || char[4] || "Yaz0" in ASCII
|-
| 0x04 || u32 || The size of the file decompressed
|-
| 0x08 || u8[8] || Padding
|}

= Decoding =
To decode the file, most programs run a loop checking the size and use a source position, a command byte, and a destination position.
The source position starts at 0x10 (16), right after the header.

= Encoding =
Encoding is a bit more difficult than decoding, often doing byte and bit manipulation. The header is still written first with the actual file data starting at 0x10 (16), right after the header
