Hey guys,

How can I achieve the following code in C++? I believe I need to use VirtualAllocEx and I am aware that I cannot use __asm in 64-bit processes. However, I am looking for general guidance and suggestions for functions that I can use to accomplish this. Although I do not require any code to be written for me, I am wondering if WriteProcessMemory is my only option for this task.

Code:

alloc(newmem,2048,"game.exe"+165D88)
label(returnhere)
label(originalcode)
label(exit)

// Define a variable to store the value
alloc(value, 8)

newmem:
// Save the value from R13+88 into R10
mov r10,[r13+00000088]

// Store the value from R10 into the variable
mov [value], r10

// Jump back to the original code
jmp originalcode

originalcode:
// Continue with the original code
mov r10,[r13+00000088]

exit:
jmp returnhere

"game.exe"+165D88:
jmp newmem
nop 2
returnhere:
