Writing specific Byte[] Array to a file

[Airslash]

Hello,

I'm currently writing a tool to help me to translate a game into English. The game in question is using .PAK files to store all it's resources and information. I've managed to understand how the .PAK files are beeing created, and I already have a tool that is capable of reading through those files like a ZIP program would do.

The .PAK file has a header that consists of the following structure:

- 4 bytes telling the amount of files stored inside.

- repeating pattern:

160 bytes : filename
4 bytes : start position
4 bytes : length
24 bytes : encoding protocol
4 bytes : version

- filedata

As mentioned the reading isn't a problem. But now I want to be able to make my own translated pak file with the same structure. So I assume I read all the files, translate them and then write them back inside the file.

But how can I be sure, that if I translate a filename for example, and wish to write it back in the header, that I actually write out 160 bytes again for the filename, and not more or less bytes. ??



p.s: i hope this question is clear...

What you could try doing maybe, is to make a class called like "PAKFile" that has like:
byte[] filename = new byte[160]

And other things to exactly match the structured parts of the pak files.
Then you just have to populate them with the write info and write it all back out?

Ok,

truth be told, I already have such a class written.



i'm sooo stupid for not realising that.....

any one know how to write specific byte array to a file

Are you planing on overwriting a file or just making a new copy?
Making a new copy is less touchy, but sometimes less usefull.
You should be able to seek in a FileStream I think?

Have a look at the BinaryWriter class.

it's to make a new file. I don't want to overwrite the existing file because it could destroy the client if it doesn't work properly.
Although its not that important cause I always make a backup before testing on a file.

The basic idea is to sniff in the pak file, translate all the japanese to English, and have a custom pak file to work with, so all text and materials ingame are no longer in Japanese but in English.

So yeah, create a .WriteToFile(string filename) function on your PakFile class (or somewhere)
and have it write out the bytes in the correct structure
