Are you trying to make a general memory dump of the game or are you just desiring the save dump code? If you need to perform a general memory dump to make hacking the game easier try PCSX2, load up the game with PCSX2 (the versions with debug memory dump feature) and get it to the point where you want and dump the RAM. If you are going for just the save dump code, and the CMP save dump pattern isn't found at all then you might need to do more digging in the game to get it to work. Not every game uses the same libraries, which is why CMP save dump pattern doesn't always exist.

Live dump. I wanna dump to my memory card, put it on a USB device, edit it on my computer. To find the things I'm looking for, I will be doing 2 dumps, and compare them with a hex editor after. That's what I wanna do. I've already hacked some things for a PS2 game called Ratchet: Deadlocked, using PCSX2 and Cheat Engine. But the game runs very slow on it, so that's why I'll be using this live dumping method.

First you need all of this stuff that never changes from 1 game to another:

sceMcClose = 030005240100062430000824
sceMcSync = 6000bfff1000b1ff030040140000b0ff

sceMcOpen & sceMcClose = 3000001038ff0224 (You should have already found sceMcClose)

When you find those patterns, just go to the top of the function. You'll know the first line of the function, it always says "FNC_????". When you are on that line, change the code to a jal to the line you are on to get the correct value you need.

SceMcSync
200A0038 0C??????
200A0070 0C??????
200A0058 0C?????? (All 3 are the same exact value of the jal you found by using the pattern, going to the first line of the function, and making a jal to that address)

SceMcOpen
200A0024 0C??????

SceMcWrite
200A0048 0C??????

SceMcClose

Done.

If you have all of the codes, you're good to go. Just play the game and dump when you want to. The CMP cube on the memory card might become corrupt, I don't remember. Transfer the dump to the computer and open it with PS2Dis. It'll say it isn't correct or something and ask you where the data starts and some other thing. 1 of them needs to be changed to where you started dumping.

What are the CMP dump saves for actullay? What do they do?

I didn't get that one, explain it better please?


Ok, so all of this are correct, right?

If they are, then I can just go and dump things whenever I want to, right?

What are the CMP dump saves for actullay? What do they do?

The data is dumped to the CMP save file so it doesn't corrupt your game's save file.

I didn't get that one, explain it better please?

Once you transfer the s dumped data to your computer, open it with PS2Dis. It will say it's not a recognized file format and will ask you where it will start reading data in the file and where you want the data to start in PS2Dis. 1 of those 2 will need to be set to the value of where you started dumping data.

I thought it would dump to the root directory of my memory card. How would I extract the dump file out of the CMP save file then?

I was actually going to use a hex editor like HxD or something, comparing the 2 dumps and maybe I'll find some good stuffs. Do I actually need to use PS2Dis?

EDIT: Didn't work. I used CodeMajic to send the codes to my PS2 through an ethernet cable, but when I pressed R3 (I even did it multiple of times) in "CAMP" and went to my memory card, nothing had changed or nothing new was showing there. So I doubt it would work with my other cheat devices (ARMAX & Swap Magic 3.8 Coder).

Why won't it still dump? Is the SceMc functions wrong, or could the dump code for this game be wrong? Is it CodeMajic?

[bungholio]

I'll check the game when I get home to find the exact codes.

Ok, thanks!

Tried them both, still doesn't dump. The CMP Dumper Saves are still 38 KB size.

[bungholio]

So there's nothing on the memory card increasing in size and no corrupt data? If not, I most likely have the wrong function for scemcopen, because the pattern didn't find it. I ended up guessing by checking near the scemcclose function and looking for things that look near identical to it.

[Hei1]

So there's nothing on the memory card increasing in size and no corrupt data?

Not that I could see, so nope. Though, I did already have a corrupted data on my memory card, but that one appeared on my memory card long time before I started using the CMP dump saves. So it's not that one.

[bungholio]

Then I'm guessing I found the wrong function for sceMcOpen. I'd say head to the CMP forums and check to see if it isn't posted anywhere. Since you are playing Dynasty Warriors 5 though and can save anywhere while playing, you really should just go for save dumping instead of live dumping. It would just be that you'd need to make a copy of your save file since it will corrupt it.
