IPU Freeze Fix Patch [PAL FFX and FFX demo]

**CKemu** · May 27th, 2006, 23:35

When IPU does a VDEC or FDEC decode command (dont ask) it puts the result in the IPU_CMD data field, this patch NOP's a line of code that is waiting for data to just be 0x4 and nothing else. Un-patched it's never getting 0x4, thus branches and causes the video to freeze, this patch simply tells it to 'not worry' about it being 0x4.

This MAY fix a variety of video freezes (caused by in-accurate emulation, that will eventually be fixed), but came about due to me 'researching' the Final Fantasy X and X demo freeze during the Zanarkand intro movie.

Refraction took my patch work and produced a simple HEX string for you guys to use, below is a simple tutourial on how to make a patch for this kind of video freeze, and attached are the two patches I produced.

This won't make a game magically work even when you are past a video

Step 01
You will firstly need ps2dis099_23.zip. Extract this into a folder such as C:\ps2dis or where ever you wish to.

Step 02
Insert your game CD or DVD into a drive (of course you will need a DVD drive to read DVD discs). Or if for whatever reason (we don't wish to know) you are using a ISO of the game, mount the ISO onto a virtual drive, using such tools as Nero, Alchol 120% or Daemon Tools.

Step 03
Load up PS2dis from wherever you put it, browse to the drive where the game is via File>Open and select the main exe (aka ELF).

The main game executable will loook like AAAA_###.##. Where 'AAAA' is SCES / SLES / SCUS / PBPX / SLPM. ###.## will be a series of numbers.

Step 04
Now go to Edit>Find Pattern:

Next tick As Hex String and put the following into the search box: 0000428CFFFF5030DBFE0316

You should have something like the image below:

Step 05
This should of jumped to a line similiar to below:

Read down from the highlighted line, where it should say bne s0, v1, $******** (-*** ▲__********) (normally two lines down), this is the line you are going to patch. On the far left there will be an 8 long number (called an address

), in this case it's 0015e760, make a note of YOUR number (eg, not the one in this example). Double check you got it written down correctly!!!! a single number / letter out will make your patch USELESS.

Step 06

Now it is time to make the patch, make a new text file, and paste the following into it:

Code:

gametitle=NAME OF YOUR GAME
comment=Skips Video Freeze
//Skip Videos
patch=0,EE,YOUR NUMBER,word,00000000

Replace 'NAME OF YOUR GAME' with well you guessed it

Replace 'YOUR NUMBER' with that number you got from ps2dis, AGAIN MAKE SURE YOU GOT IT DOT ON!!!, save the text file!

Step 07

Put the *.txt file you just made into the patch's folder of PCSX2. Boot PCSX2, and enable Console and patchs

Yes I know this is a shot from an old build, but I couldn't be fussed to make a new shot when the GUI is identical except V number and image

Then run the emulator (making sure it's setup to read from the drive you have your game in!

PCSX2 will not be able to find the patch, don't panic! In the console output (which you just enabled), the CRC of the game will be meantioned, in this case A39517AB. Make a note of YOUR CRC.

Close the emulator, and go into your patch folder, rename the text file with your patch in it, to YOUR CRC.pnach (replace 'YOUR CRC' with the number you just got from the console title.

Voila you just made a patch, re-run the emulator (making sure you leave 'enable patches' ticked), and the game may get further, if you get any results, post your patch with screenshots in the screenshots thread.

Great CKEmu, as usually.

Is there a way to know that one game is freezing because of this problem? or is just a matter of try making the patch?

if this: '0000428CFFFF5030DBFE0316' exists means that the game will freeze or it exists always?

Thanks

not necesseraly, it means that its a possible place that it will freeze, if you know the game to freeze on the video and it has that string, patching it might solve the problem.

Cheat tools like AR Max or Xplorer uses hex strings to to apply an cheat right?
so would it possible to apply an cheat as Patch?

i post this question a long time ago and i don't want to bother.

cyclonmaster · May 28th, 2006, 12:46

Yes, you can make a cheat for some games. Refer to Nachbrener patch guide site here:

it's possible to cheat via the pnach system, but you would have to convert the AR code to raw HEX via a decryptor (they are readily available), and I would assume do something with the master code as well, but you have a debugger and thus essentially all you need to write cheats.

where can i find final fantasy X patch (US version) .. thankz

Ex0skelet0r · July 13th, 2006, 22:45

With this patch we can watch the videos without problems or the videos with problems will be skiped?

Kekko12 · July 13th, 2006, 23:18

Hi!
I own a copy of Final Fantasy X Ita and I tried to create a patch that allows me to play, (I.E. skipping the main video).
I followed all the instruction but I get always an hang of Pcsx2.
Is, for this version of the game, different the hex number that I have to insert in Ps2dis, or is it a problem of different nature?

This is the content of my own patch

The CRC is a39517a9

gametitle=Final Fantasy X
comment=Skips Video Freeze By Kekko
//Skip Videos
patch=0,EE,0015e760,word,00000000

When I submit the Hex number (0000428CFFFF5030DBFE0316) I obtain your same blu screen without the number
after the delta(__0015e2d0).
Also the number of your CRC is different from mine.
I hope you can help me so that I can post a patch for all the owners of this version of the game

Thank you

The crc should be different, as the version of the game is different. Each crc is unique to each game. As for the missing number, could you send a screenshot of what it looks like?

Kekko12 · July 14th, 2006, 15:40

The CRC requested from the game was a39517a9. It was displayed in the name bar of the console. So, I named the text file as a39517a9.pnach.
But now the game finds the patch but it crashes the same (without requesting me the patch).
So I suppose that the problem is in the hex number that should be different from the one in the guide. Is it correct?
(I don't now how to post a screenshot, sorry)
The file opened with ps2dis in the DVD is SCES-50493.

THANKS AGAIN
