Cheat Engine

[god22]

I got back in to playing ar tonelico recently and was messing around in cheat engine with it. I made a script that will multiply the amount of exp gained after battle but it was way to high. Upon closer inspection, I found out that it was writing to 2 16 bit registers. It would write correctly to the first part but only until it maxed out the first register. It would then overflow into the other part. in decimal form it would say something like 3300| 0->9452 | 31. I have no idea how to fix it.

Show the code you are trying to use.

newmem:
push ebx
mov ebx,[20D20B54] //MC Exp

code:
mov [ecx],edx -> copy calculated exp to memory
sub ebx,[20D20B54]
neg ebx
add [20D20B54],ebx
pop ebx
mov [pcsx2.exe+10922F8],00186A24 //?


Expected:
1. Store exp before exp gain
2. Run orginal code
3. Subtract new exp from old exp
5. add the result to the original exp (creating double xp)

Actual:
0 or 1

Tried:
shl returns a negitive I think

modding edx returns a weird value due to how the emulator calculates values

Can you jump from cheat engine to a lua script and back? That would be the best solution I think.

To deal with WORDs (16 bits) you just remove the "E", it's for "Extended" and it was actually added to the 16 bit registries to denote 32 bit. So; AX (16 bits), EAX (32 bits); BX, EBX; CX, ECX; and so on.

Thank you for your help. I will try that.

To clarify:

mov [ecx],edx // This is the code that adds exp.


I don't think I can find a code better than that because it isn't a game but an emulated game. Therefore,I was trying to store the old exp before it was changed and subtract it from the new exp. I could take that value and manipulate it however I wanted, or so I thought.

Something like this should work.

It went to 1 again. While it didn't work, it did confirm I need to find a different code to use. Oh well. Sorry for wasting your time.
