Heck, you should not even think of being a hacker.
If you want to find out how to change the sound of the missile launcher, I would suggest two things.
First and Foremost, USE THE SEARCH BUTTON! I know this has been posted before, you should STOP relying on other people, and use your brain for a change!
Secondly, screw around in a hex editor, various mods (Original Sin) have changed the sound of a weapon, and you can find this data out by changing values in the hex editor.
In the words of the immortal Runelancer, a journey of a thousand miles begins with a single step, not by hopping in a taxi. If that is what you want to do, turn around and go home, No one wants a leech on the forums.
[saracsm]By the way, you are very mature, the way you thank us for all the help we've given you so far, instead of pestering us with countless more questions, the answers to which that you are to lazy to understand, and even to lazy to try to understand, thank you, thank you very much. [/sarcasm]
Seriously though, if you aren't even trying to understand the advice we give you, you shouldn't be a hacker.
Thank you, and please go home.
