Based on the fact that format #1 seems more common with older games suggest this is the earlier version of the format thus labeled as format #1. The second format appears more often in newer releases thus is labeled as format #2. There are some games that even use both at the same time. Further testing could be done to see if any games can or cannot read either of these known formats. This could help gauge what era the licensed engine game from. Possibly to help predict what formats are expected or how the engine handles it's data.

As of this revision, in format #2 the last 4 bytes in the header are still unknown but so far, appear static in most, if not all format 2 archives. This could be some sort of version or support check but testing would need to be done if this value means anything, if changing does anything, or if it is even read and stored in memory.
