FF3us/FF6j Monster Formations Packs, written by Lord J, May 2000

These "packs" are indexes to monsters formations. There are two banks
of packs, the first one having four possibilities per pack, and the
second having only two possibilities.


One may compare this to the morph packs. E.g.: When you walk around 
Narshe, you have four possible monster formations you can encouter.
The engine randomise a number and will choose one of the four possible
formations encouter. This is the place where the "possibilities" are
programmed.

I am not aware of the weight of each possibilities, that is if one
possibility is harder to get (thinking of the encounter with the
brachausaurus)

Most interesting is the MSB of the index. If set, the engine will
randomise the particular possibility once again, but this time with
the following 3 indexes of the selected formation. This feature is not
used by the game anyway.

Descr.: 1/4 formations encounter
Base: F4A00 FF3us/FF6j
Length: 4 words (indexes to monster formations)
Number of tmp: 256


The next offset works the same way, at the exception that only 2 
possibilities can occur.

Descr.: 1/2 formations encounter
Base: F5200 FF3us/FF6j
Length: 2 words (indexes to monster formations)
Number of tmp: 256
