Cheat Engine

[hju]

I want to make my code permanent by modifying the assembly code with cheat engine. To change the value of xmm register, it must come from another address and i don't know how to create a new address and assign a value to it. I just simply want have fixed value(500) of XMM12 register.
My plan is to find a code cave jump there, set 500 to [x], set xmm12 to [x] and jump back.
Thank you.

do the code injection with your codecave (so get rid of alloc)

and then tools patchscan

select all changes and rightclick. there is a option somewhere to save the changes to file

Thank you. Couldn't make it work but i managed to do it by assigning value to the register.
