The OFP Manager tool available for download on this site in the Editors Depot seems to be the most reccomended one if you care to read 8-12 pages of threads back, else do a search and hope for the best.
It does require a 21mb .net environment download and installation prior to using it.
Be warned tho! It does not convert/decrypt all config.bin files as you would HOPE it would. I was trying to do something so monosyllabically simple like oh, CHANGE a freaking rifle for another rifle on an addon, god forbid, and it's been dissapointing to say the least. OFP Manager could properly VIEW and EXPORT only portions of the file.
If you take a simple UNPBO tool and UNPBO an addon, then dump the config.bin into a text editor - you'll see a lot that OFP Manager missed when you compare the two config.bin files. Hard to give the reason why.
The difference is editing this;
class CfgModels
{
class Default
{
};
class Man: Default
{
};
class Rifleman: Man
{
sections[]= {"head injury","body injury","l arm injury","r arm injury","p arm injury","l leg injury","r leg injury","p leg injury","medic","hlava","krk","zasleh"};
sectionsInherit="Head";
};
Instead of this;
00 04 00 00 0A 00 01 10 00 ..etc etc etc
Just keep doing your homework and keep asking - you're bound to figure it out eventually. Irregardless of anything - nothing comes for free.
