. if you could help out with this I'm sure the modding community would much appreciate it.

Like I mentioned before x64 isn't my strong suit so I need a bit of assistance with this one.


Titanfall 2 has

*VPK
*RPAK
*STARPAK

VPK fileformat hasn't changed since TitanFall 1 it still uses the modifed Valve format with lzham
compression.

RPAK contains a header which has a string to the starpak that contains the contents of its data
0x67 bytes in.

image base: 0x7FEE2880000

sub_7FEE28831C0((__int64)&v43, 257i64, (__int64)"r2\\paks\\Win64\\%s", (__int64)v5);

is used to combine the paths to form a full path to the data

so for example.
paks\Win64\mp_homestead_loadscreen.rpak

contains starpak
paks\Win64\pc_all.starpak

sub_180008C80 inside rtech_game.dll loads the paks

Hooking ReadFile also points to rtech_game
