Cheat Engine

abahbob

Me and some other people are working on a TAS of The Wind Waker. We are using Dolphin emulator. Dolphin's built-in memory watch is a piece of crap, so we use Cheat Engine. The problem is that every time you open Dolphin, the addresses change. There are a lot of values to keep track of, and its amazingly frustrating to find them every time. It seems like Dolphin chooses a random place in the RAM to open up, and I don't know how to stop having to search over and over again. Right now I just find one value and find all the others based off of that position, but that is time consuming and a head-ache. Any help? Please, check it out yourself if you don't mind.

have you completed cheat engine's tutorial ?
in ce 6.2 it help and then choose tutorial.
complete it, and you'll have no doubts.
i also recommend to find the code instruction that writes to that address, and if the code address is not a static one, find the aob scan for it and code injection.
all those terms i used now are all in the tutorial, take it and then reply here the results if necessary.

Yes, emulators are particularly difficult to deal with. You need to find out where the allocated memory begins and find a pointer to it in the emulator itself (or a piece of code that uses that pointer).

then i guess, your only solution is an aob scan, the code will activate very slow, because ce will try to search the bytes.
but it'll work.
you basically find the code that writes to the address and copy the bytes from that address on, watch for any instruction that uses addresses like:
mov eax,[0000ABC0]
it's most likely that abc0 will be changed by other codes, so don't include that kinda codes in your aob scan.

or, ask the developers of the emulator to include some basic assembly debugger into their emulator, so that you can find the real code that writes to the memory instead of that single code line that does everything.
i know that because few weeks ago i was trying to do the same thing, turned out by searching google that there was a better emulator with more features and of course a debugger, and therefore i was able to find everything i wanted, with a little bit of research (assembly manuals [instructions] for that type of cpu that was emulated)

It's a very dangerous thing to modify the code of emulators, but sure, knock yourself out.

maybe the address has a specific structure, like xxxxxC89 and based on that c89, even if the code writes to 100 addresses just one will end with c89, therefore, he could do a code injection. Smile
