I need help with a certain exstention.

[moris]

I need help with .cpk to uncompress it, but it is also packed with RST and i dont know how to unpack it any software out there that can do this?

[luck of the irish]

what will you be doing with the uncompressed file?

[Mulreay]

Better still where did you get it from (email?) And why is it in CPK format?

[moris]

here is an example and no i am tryign to edit the file and id idnt get it from email but from a game trying to see if i can do soemthing.

Were not here to Hack programmes mate. End of.

[luck of the irish]

That is what I needed to know, unforutnately for you we are not a site the promotes the piracy of games or the hacking of them, I am sure Sega did not intend for you to use the game the way you are planning to.

[billrich]

You have displayed a complied exe program.

To read the program, You need the source code before it was complied.

You will need to contact the company that created the program ( complied exe file ).  They might sell the source file but I doubt it.

[BC_Programmer]

Billrich is right- it's far easier with the source code. On the other hand, a lot of games store a lot of stuff in configuration files- for example, Duke Nukem 3d has external "CON" files which determine the behaviour of the in-game enemies. Barring that, depending on what game it is, there might be a number of useful tools you can use. Another possibility might be to dissassemble the program itself- this will transform the machine code into assembly code, which won't be anything close to the actual source code they used, but is a lot better then trying to edit bytes. The downside being that the only disassemblers I know of come with paid programs- Such as Visual Studio and IDA Pro, However, there is a free version of Visual Studio .NET that may (or may not) have a usable disassembly view.

I am sure Sega did not intend for you to use the game the way you are planning to.

Sega? where do you gather it's a Sega game?

[Aegis]

�����

Now squint.  See?  Sega!   

[BC_Programmer]

hmm... maybe if I print this off, and apply heat as a investigative tool, I can determine the source of the company name...

[Aegis]

Yes, the heat should be at 451 degrees Fahrenheit, at least according to the title of a famous science-fiction novel.   

[Mulreay]

I think you are being a little harsh Gents. If you search for these files on Google then Sega pops it's head up everywhere. The guy's a starter not a Mod. Plus since when do we show how to 'break into' programmes? Carbon has already shut a double post down saying that we don't help we these problems. So I'm lost to know where this is going?? 

[Aegis]

We're just teasing -- and the 'heat as investigative tool' is reference to another thread...

[BC_Programmer]

If you search for these files on Google then Sega pops it's head up everywhere.

It's a windows PE executable. I'm not sure where the OP got the CPK from either- but it is a windows executable, not a CPK, or RST file.

[Mulreay]

here is an example and no i am tryign to edit the file and id idnt get it from email but from a game trying to see if i can do soemthing.

Is that not hacking a programme then BC? I asked originally where he got it from he admitted it was from a game programme.. could of been Sega just to stand up for 'luck of the irish' he did the right thing. And so did Carbon where he dismissed his second post telling him we don't deal with these issues. I'm either totally wrong and I bow my head and apologise or I'm just to stupid to understand the rules anymore.
