God ****** it cannt be put into full screen and looks so blurry. Well, anyway here's the method without the video if the vid doesn't help (which I'm guessing it doesn't. stupid acidplanet)
1. Make a backup of your original SniperHair - SniperHair_4 files at ur Blackshot/Data/Scene/Screen .
2. Take the Sniper Crosshair you want -
SniperHair - PSG
SniperHair_2 - M24
SniperHair_3 - Secret Crosshair
SniperHair_4 - AWP
3. Copy it and paste it three more times in your Blackshot/Data/Scene/Screen
4. Also delete the original SniperHair files except for the one you want to use.
5. Rename them to SniperHair - SniperHair_4.
6. Enjoy

[Tutorial] How to change background music founded by Mution earlier than me
Original Thread : http://forum.blackshotonline.com/thread.asp?qid=10489&page=1&
1. Go to your BlackShot/Data/Sound/UI
2. The files you can find there, 'music01.mp3' and 'music02.mp3', are your background music. All you have to do is to put the music you want to have in that directory, then rename them into music01.mp3 and music02.mp3. Both of them must be inside, even if you want to listen to only 1 song, you should put two copies of the song and rename them as stated above. Remember that the original mp3s shld be either put elsewhere or deleted.
3. Turn on BlackShot and enjoy nice music while waiting for games to start

Thirdly
[Tutorial] How to change weapon appearence
[I DID NOT LEECH THIS FROM THE CHANGING KNIFE TO CANDY CANE THREAD]
1. Go to your BlackShot/Data
2. There're 3 folders you have to take note of. Items (3d and animated images of the weap are here), Character/HandAni (how your hand and the weapon moves while reloading, shooting, etc. are here) and Sounds/Weapons (sound of the weapons are here). Remember to make backups in case you want the original appearence.
3. Take it that I'm gonna replace m24 for awp (take note, you shldn't replace totally different weapons, causing different weapon frame rate). I take my m24 files and rename them into awp files. This is how it shld be renamed into.
m24.kf --> awp.kf
m24.kfm --> awp.kfm
m24.settings --> awp.settings
m24.nif --> awp.nif
m24_3ps.nif --> awp_3ps.nif
m24_Anim.h --> awp_Anim.h
This is the normal 3d animated images files you only have to replace.
4. Do the same for the m24 files in the Character/HandAni
MaleHand_m24.kf --> MaleHand_awp.kf
So on and so forth...
5. Just rename the m24 sound folder name and the sound files inside
m24 --> awp
m24_clipin.wav --> awp_clipin.wav
So on and so forth
Note that the original files should be kept as backups
