=== Notes and Comments ===

* NOTES ON WORKING OUT THE SIZE OF EACH FIELD 
This archive format swaps between using byte(0) and byte(32) to represent null values. Therefore, you need to do the following to work out the size of the 4-byte fields... 
1. Read the first byte (it will always have a value) 
2. Read the second byte 
3. if (byte2 != null AND byte2 != 32) then it is part of the value, else it should be treated as a null 
4. Repeat steps 2 and 3 for the remaining 2 bytes 
 
This way you will build up the 4-byte value correctly. You could also do it the following way... 
1. Read the 4 bytes 
2. Working from the last of the 4 bytes, replace bytes with value byte(32) with value byte(0) 
3. Stop when you reach a null, or when you reach a value != byte(32) 
This process should be applied to all the fields marked as size 1-4 (and its partner 0-3) 
 
* NOTES ON THE FILE DATA 
There are no offsets stored, rather the user must walk through the file to find the file data offsets. To help, there is a rough pattern in that the 4 bytes before the data starts is the length of the data. Other than that, I don't know how to move between files, or how to determine the location of the size field. So, at this point in time, i do not know how to get the specific file
