Let's say I have found a ram value for money or score, and I wanted to keep it stored in a variable outside of the program's ram - so I can keep the value saved even after I close the game.
What would be the easiest way to achieve that? Would that require me to know LUA scripting or C programming?

some basic LUA and a bit of assembler knowledge is needed

First this lua command:
Code:

sharedblock=allocateSharedMemory("anameyoumadeup", 4096)
print(string.format("The block is now at %x", sharedblock))
registerSymbol("sharedblock",sharedblock)


this will allocate a block of memory that will keep it's contents even when the process has terminated.
To access it again, just target any other process (could be a new instance of the game) and then execute that lua command again.
The new process will get a memory block with the previous contents (the address can be different so keep that in mind)

e.g to use it in a code injection:
Code:

alloc(newmem, 2048)
label(returnhere)
label(originalcode)

newmem:
mov [sharedblock+xxx],ecx

originalcode:
...
jmp returnhere

12345678:
jmp newmem
returnhere:


then when the game has closed target a new process and execute the lua command. Then you can watch the previous memory, or re-activate the auto assembler command so it hooks it again and updates the new location

One thing you need to keep track of though is if you've already executed allocateSharedMemory once in that process as it will make a copy every time, even if it's already in. Which could eventuality (after 30 thousand times or so) make the game run out of memory
