For all the Amazing people who play arma 2 and Oa , here is how to bypass the 'new' bi 2 signature checking.
Bi sign 2 bypassing is basicaly quite a simple challenge , It relys upon the file sizes and the pbo size in the header of the pbo.
info:
ascii '.bin' 00 00 00 00 00 00 00 00 00 00 00 00 34 21 44 10 19 00 00 00
Fake the size in a packet and then Fake the end 20 bytes and that is all there is to it.
You can use the above method or infact you can edit the pbo with a hex editor , However if you deem to do it this way make sure the file size is exact to the origional pbo or you will be rejected in the game lobby.
Ofcourse there are other ways to bypass but this is the simplest way.
If it is patched i will release more information on the other ways of bypassing.
Have fun.
nice,. post ... you will be getting 100+ pms when they get lost ...
i hope everyone understands the basics of this ...
id give a hand but im not into giving out info of bypasses just for sake of , i like everyone being 3 or steps behind me ,...
but this method is the beginning of biger things if anyone desides to look further
+1 for figering some of it out .
