This code can't be injected for some reason, [154200CB670] is a float value from the original code of the game.
Code:
[ENABLE]
alloc(newmem,512,1551DACD49B)
label(returnhere)

newmem:
  movss xmm5,[154200CB670]
  movss [rsi+50],xmm5
  jmp returnhere

1551DACD49B:
  jmp newmem
returnhere:
 
 
[DISABLE]
dealloc(newmem)
1551DACD49B:
  db F3 0F 11 6E 50
//movss [rsi+50],xmm5

Why ?

RIP-relative addressing probably
Code:
push rcx
mov rcx,154200CB670
movss xmm5,[rcx]
pop rcx
movss [rsi+50],xmm5
jmp returnhere
