There is model data that seems to be structured as if it were an external file, but is baked into the BATTLE.BIN file. for constructing projectile models.
801b8534 - pointers to start of model data
	Arrow model   - 801b69dc
	Stone model   - 801b6d00
	Reflect model - 801b6f00
	Shuriken model- 801b73b8


Section 1

the first section is dedicated to address pointers? may be split into 2 sections? using the arrow model as an example:
          AA AA AA AA|BB BB BB BB|CC CC CC CC
00000000: 41 00 00 00|00 00 00 00|01 00 00 00

I cannot be sure these 3 are pointers, because they aren't treated that way? unsure what their purpose is yet. 

Section 1.5?
          DD DD DD DD|EE EE EE EE|FF FF FF FF|GG GG GG GG|HH HH HH HH|II II II II|JJ JJ JJ JJ
0000000c: 01 e8 00 00|13 00 00 00|80 02 00 00|13 00 00 00|1c 00 00 00|11 00 00 00|00 00 00 00
  • DD:
Used as a pointer relative to 0x0000000c. points to a table of raw points in xyz space. EE points long.
  • FF:
Used as a pointer relative to 0x0000000c. Data seems to be completely superfluous. safe to remove/ignore? GG entries long.
  • HH:
Used as a pointer relative to 0x0000000c. points to palette data per polygon, that is II polygons long.
  • JJ
does not seem to be used?

Sections DD, FF, and HH may not be in sequential order in the file; in this case, HH is first.

Section DD

Contains exclusively point position data.
         XX XX YY YY|ZZ ZZ 00 00|
DD:      32 00 32 00|00 00 00 00|...

Section HH

a Table related to vector data that is, admittedly, yet to be tracked down; HH points to this table. the following can be said about it though:
         AA BB CC DD|Palette 1  |Palette 2  |Palette 3  |Palette 4  |Vector pointers?       |AA BB CC DD|
HH:      08 06 01 39|56 56 56 39|bd bd c1 00|3e 3e 3e 00|a1 a1 a6 00|00 00 01 00 03 00 02 00|08 06 01 39|...
AA BB CC are unknown.
  • DD
Polygon type. includes semi-transparency flag.
  • Palettes
RGB palettes per corner of model.
  • Vector Pointers
point to the points in xyz space that make up the polygon.
