There is a program, it is not all in 1 exe, it is the program and ~5 seprate encrypted files,
I used ollydbg and it makes NO call to module MBX@ ect... like others I'v seen the tutorials.
It doesn't even mention the outside protected files, I'm lost , I need a little guidance please.
I know what the 5 files are supposed to be, but when I use the tool to open them I get an Unknown Archive error, I have tried to extract the main executable but I couldnt, I steped in to it 3 times and I got this:
There are two JMP EAX
when I step into it it takes me to
7C812A5C C9 LEAVE
I'm lost on it.
I havent seen a tutorial on unpacking add-ons.
Basically I insert code into the exe that handles the encrypted file. So when the client opens the file it checks to see if its encrypted or not. If it isnt then it uses the standard code if it is then it uses the encrypted stream code and then the standard code. Its relly simple to say but extreamly complex to accly do. The setup is a challange in it self. The other main issue is that you cant patch encrypted files. Once you are done with a production grf you encrypt it then ship it off. But sence none of the patchers can handle encryption they cant patch the files...
