## Unknown Data
The unknown data usually starts with some file offsets. Most of this data is empty.
I don't understand yet how this data is used but there are some patterns that emerge when comparing different files.
### Header
The unknown data starts with an info for the number of entries each file has.
|Size|Description|
|---|---|
|$4|Number of entries (in little Endian)|
|$4|Entry offset (in little Endian), calculated as (Unknown Data Offest + Entry Offset)|
The header is padded with `FF FF FF FF`.
### Entry
Entries can have multiple frames? I'm not sure what each of these items in each entry are so I am calling them "frames" for now.
|Size|Description|
|---|---|
|$10|Number of frames|
|$60|Size of each frame info|
### Frames
Again, not sure what these are but they seem to have a format. It's not very consistent across files though.
|Size|Description|
|---|---|
|$4|Some value? Usually less than $10 in smaller files|
|$2|Another value? Usually less than the previous value|
|$2|Another unknown Value that is somtimes used|
|$4|Unknown value, when not empty is usually larger than `$FF000000` (in little endian)|
|$4|Unknown value again|
The rest of each frame is usually empty and padded to be a total of $60 bytes.
