I think coalesced bin files contains some form of "compiled" ini files. These files are not packages.
Well i have checked that and all Bin file contains more files wiht the texts. I know files are not "packs" like i would like to call it, but i would say they are in their own way. In this kind of files is system, just dont have enought knowlidge to figure this out. I think once you find the correct system and algorithm u will be able to do it with all Unreal based games for any console system, also should mention they are Big Endiannes.
Could you think and try to do something about it pls?
