Bytes wont work [EU]

hey guys, when i do this :

if((*(BYTE *)GameStatus == 1) && norec)
memcpy((VOID *)NoRecoil, (VOID *)(PBYTE)"\x90\x90\x90\x90", 4);
else
memcpy((VOID *)NoRecoil, (VOID *)(PBYTE)"\xD9\x44\x24\x14", 4);

norecoil doesnt work at all ;o and i checked the bytes with this adress:

0x37383DFC

Whats the problem?

same problem with:
rapidfire
superbullets

if((*(int*)GameStatus == 1) && norec){
memcpy((VOID *)NoRecoil, (VOID *)(PBYTE)"\x90\x90\x90\x90", 4);
}else{
memcpy((VOID *)NoRecoil, (VOID *)(PBYTE)"\xD9\x44\x24\x14", 4);
}

Now it will work.
