Need advice bout pack/unpack files...

Hi guys.
To begin with, thank everyone who reads this thread and sorry for my poor English.

I usually play an online game called Audition. I love it and now want to modify it. Just to make it more interesting and see what I can do ( not like make tools or hacks ). In the game folder, I found a lot of files which have to be decoded, or unpacked/packed in order to modify it. Like .acv, .bin... Just wondering if anyone can look at them I tell me what I can do, what books I can read or so. I am a newbie in C/C++ so the more details, the better. I really really appreciate..

Here is the link to download some files..

Have a great day

abm, tbm, dxm are music files. acv is a image file. dll is a library file, and bin can be everything.

..and what books or knowledge should I learn in order to open it..

I think you are looking in the wrong way at your goal. The first thing you need is some basic programming skills, second, you need to know what the game does with the files. For instance, maybe the game checks if you changed/replaced the files, or maybe the game simply doesn't work if you change the files. The programming part is probably not the biggest problem (something like ... open file, change the data, save file). The big problem is to know what to change. My advice would be, google for all the files and what they do based on the file extensions (or looking into them with a hexviewer). Maybe there is a forum for game support, and you can post some questions there. Keep in mind that you probably are not allowed to change the files based on copyrights or something like that.

So, to answer your book question... look for a basic programming book

I'd recommend 3 paths:

1) google each of the file extensions with "format," "player," "viewer" or "editor" :
.acv format
.acv editor
etc.

See if you can successfully modify some/all of the files. Expect to spend hours or even weeks just doing this... no pain no gain, right?

2) find a game that is DESIGNED to be modded. Unreal Tournament, for example, comes with very advanced game-mod tools, and you can find plenty of online tutorials (including videos) showing how to make your own levels, modify characters, and everything else. Most RTS games, like Starcraft, are designed to be modded quite easily.

3) everything Skizmo said.
