Version
Just as for other OSBD, there have been several version of the binary format.
Over time, some fields that used to be hardcoded became customizable on a group-per-group basis.
Thus, later versions include some extra fields as compared to earlier ones.
The above example belongs to the latest OSAm version encountered in Oni: 6.
Lower versions lack certain fields, and the following content is simply shifted backwards.
Versions of OSAm occurring in Oni are 4, 5 and 6.
