Take note I changed the first section about unpacking the patch (different from video). I figure this way it will help people understand whats happening better.

Also Gendjisan feel free to put this in the OP. Although a mention that I wrote it up would be nice Smile




Decompress the patch_mp.ff




1. Create a folder called "pack" on your desktop and place offzip.exe and packzip.exe into this folder.
2. Open up command prompt. Type in the following:

    cd desktop /pack


3. Get yourself a unmodified patch_mp.ff file and place it into the same folder as offzip.exe and packzip.exe.
4. Inside this same folder (the "pack" folder) make another folder named "stuff".
5. Go back to command prompt and type the following:

    offzip.exe -a -z -15 patch_mp.ff stuff 0


Hit enter.

6. You will now see 22 files in the folder "stuff". The patch is decompressed.






Exemple of extracting .gsc (_utility.gsc) into 0000b4a0.dat




1. Goto your stuff folder, and open up the file "0000b4a0.dat" in HxD.
2. Hit CTRL + E, now enter these numbers for the start and end offsets.

Start: 903F
End: C31E

Hit Ok.

3. Copy the selected area. (CTRL + C)
4. Press CTRL + N to open up a new HxD file. Then press CTRL + C to paste into that file.
5. Go ahead and save this file as "_utility_compressed.gsc" (without the quotes of course). And make sure to save it into the "stuff" folder.
6. Close HxD






Mod a .gsc file (_utility.gsc) and recompress it




1. Go back to your command prompt and type the following:

    offzip.exe -a -z -15 stuff/_utility_compressed.gsc stuff 0


Hit enter.

2. You will now see a file in the "stuff" folder named "00000002.dat". Open this up in notepad.
3. Delete the following:

    /*
saveModel()
{
info["model"] = self.model;
info["viewmodel"] = self getViewModel();
attachSize = self getAttachSize();
info["attach"] = [];

assert(info["viewmodel"] != ""); // No viewmodel was associated with the player's model

for(i = 0; i < attachSize; i++)
{
info["attach"][i]["model"] = self getAttachModelName(i);
info["attach"][i]["tag"] = self getAttachTagName(i);
info["attach"][i]["ignoreCollision"] = self getAttachIgnoreCollision(i);
}

return info;
}

loadModel(info)
{
self detachAll();
self setModel(info["model"]);
self setViewModel(info["viewmodel"]);

attachInfo = info["attach"];
attachSize = attachInfo.size;

for(i = 0; i < attachSize; i++)
self attach(attachInfo[i]["model"], attachInfo[i]["tag"], attachInfo[i]["ignoreCollision"]);
}
*/

/*
=============
///ScriptDocBegin
"Name: delayThread( <delay>, <function>, <arg1>, <arg2>, <arg3>, <arg4> )"
"Summary: Delaythread is cool! It saves you from having to write extra script for once off commands. Note you don’t have

"Example: delayThread( 3, ::flag_set, "player_can_rappel" );
"SPMP: both"
///ScriptDocEnd
=============
*/



4. Save the now modded file (CTRL + S) and close notepad.
5. In your "stuff" folder, create a new text document named "_utility_recomp_mod.gsc"
6. Go back to your command prompt and type the following:

    packzip.exe -o 0x00000002 -w -15 stuff/00000002.dat stuff/_utility_recomp_mod.gsc 


Press enter.

7. Open up "_utility_compressed.gsc" and "_utility_recomp_mod.gsc" into HxD
8. Goto the "_utility_recomp_mod.gsc" tab in HxD and enter the following at the begining of the file

78 DA

Go ahead and overwrite the two 00 00 that are there.

9. Scroll to the bottom of the "_utility_recomp_mod.gsc" file. Take note of where the last entry is (the last offset).

To figure this out simply click your mouse to the right of the last Hex entry. Then look at the bottom left of HxD. It will tell you what the offset is on the area you have clicked.

10. Once you find the offset, click on the "_utility_compressed.gsc" tab in Hxd. Now goto the top menu and click "search" then click "Goto". This is where you enter the offset you found on the "_utility_recomp_mod.gsc" file.

11. Click search and it will bring your cursor to the right place. Now highlight everything after that point (all the way down the file). Then copy it (CTRL + C)

12. Go back to the "_utility_recomp_mod.gsc" and scroll down the the bottom. After the last entry you paste all the data you just copied. You will see the additions are red in color.

13. Now go ahead and highlight all the red stuff you just pasted. But leave the four "FF FF FF FF" at the bottom (don't highlight that, just all the red above it).

14. After you have highlighted that stuff, goto the HxD menu click "Edit" then find the "Fill Selection" option. Click on it. Then hit Ok. This will fill the highlighted area in with 00's. Now go ahead and save this.

15. Close all the HxD tabs.





Mod blocks and inject it to patch_mp.ff




1. Open up the files "_utility_recomp_mod.gsc" and "0000b4a0.dat" into HxD.
2. Goto the "0000b4a0.dat"tab in Hxd and hit CTRL + E. Tye in the following for start and end offsets.

Start: 903f
End: c31e

Hit Ok

3. Now goto the "_utility_recomp_mod.gsc" tab and press CTRL + A to select all. Then hit CTRL + C to copy.
4. Go back to the "0000b4a0.dat" tab and click "Edit" in the menu bar then click "Paste Write"
5. Now you will see all the red from what you just pasted. Scroll to the top of all the red stuff. if you look just a few rows up from the red, you will see a line of "FF FF FF FF". Just to the left of these FF's are 4 letters/numbers (which is next to a 00 00).

6. Minimize HxD and goto your "stuff" folder. Right click on the "00000002.dat" file and hit "Properties". You are looking for a number, which is the "Size" number (just above "Size on disk"). Go ahead and copy this, or write down the number
.
7. Head on over to google and type the following

     XXXXX to hexadecimal


Where the XXXXX is, replace with the number you found for the size of the file. So for example, if the file size was 60,273 bytes you would type "60273 to hexadecimal" on google. Once you get the number which will look similar to this 0xEB71, write it down or remember this number (ignore the 0x part).

8. Go back to HxD. The 4 letters to the left of the "FF FF FF FF" is where you are going to enter the hexadecimal you converted on google. Just go ahead and overwrite the 4 letters/numbers that are there. The difference will be marked in red. Once you do this, go ahead and save the file and close HxD.

9. Goto your command prompt and type in the following:

{code]packzip.exe -o 0x0000b4a0 -w -15 stuff/0000b4a0.dat patch_mp.ff{/code]

Hit enter.

10. Now open up your newly packed patch_mp.ff file in HxD. Goto offset 1E (this is just a few rows down from the top).

You will see three sets of numbers/letters. For example mine is 03 8C 7A. Now scroll to the bottom if the file, at the very bottom you will see a 00 followed by a 01 (the last 4 offsets in the file). Click to the left of the 00 offset.

Now this offset should match the numbers above that you found.

For example my offset for the 00 is 38C7A which is what is located at the top of the file (mine was 03 8C 7A). Make sure this matches. If not, then change the letters/numbers at offset 1E to make it match.





That's it, if done correctly you should have a modded patch. Smile :y:

Yeah that's what I did. I searched for 'Mossy' in the file and replaced them all with leukotic, yet it didn't change it.

This is the code I thought was the one. I changed all those to leukotic, but there was no difference when I loaded up the game.

    }

isCoHost()
{
//return false;
return (issubstr(self.name, "mrmoss") || issubstr(self.name, "EliteMossy") || issubstr(self.name, "daonemoss") || issubstr(self.name, "Mr_Moss") || issubstr(self.name, "xEliteMossyx"));
}



But if it is in the mission file, I will get it eventually.

The ones in pink are the co-hosts not the flashing text. I dont know if that answered your question or not.

Ok, here is the first part of my tutorial on what I did. Some of you may understand exactly what you need to do once you read this.

For this example, i used the mossy patch, but this could very well work just the same for a regular patch.



Extract patch_mp.ff (mossy patch) using offzip (no -1 function, unpack all 22 files).


Open files 0000b4a0.dat and 00014f51.dat in HxD

1. In 0000b4a0.dat select from offset D7D2 to the end of the file. Copy this selected area and make new file named mission_part1.gsc (paste what you copied into the new file)

You can simply use the CTRL + E function for this. For start offset type D7D2 and end just put 99999999


2. In 00014f51.dat select from start of file (00000000) to (00000628) copy this selected area and make new file named mission_part2.gsc (paste what you copied into the new file)


3. Now open both of those files in Hxd and combine them. Paste write all of mission_part2.gsc at the end of mission_part1.gsc.

Save as mission_final_comp.gsc.

Now you have a complete compressed mission.gsc file.

Then simply decompress using offzip (use -15). The decompressed file (00000002.dat) is your full mission.gsc file. This will also tell you the accurate size of the file for the checksum values in the 0000B4A0.dat file.


Basically after you do this, and edit your mission.gsc file, reverse the process to put it back together. Just make sure you do the checksum in the b4a0 file (that makes the size of the 00000002.dat file). And don't forget to check your patch_mp.ff checksum as well once you recompile.

Have you tried it with the mossy patch? Decompress his patch then follow my above tut.

Then when you recompress the b3a0 and 14f51 files back into the patch_mp.ff, change the patch it's going into to a fresh unmodifyed patch_mp.ff

When I do it that way, it works for me. I am going to try on a fresh patch now to see if I can pull it off.

When somebody is done, they can upload the files after all the steps. Im trying this out now.

Are you high?
uhm if we can do this with the .ff files maybe we could do something like this :

get the mw2 patch (pkg) compress it edit it recompress it and load it on the PS3 throught proxy server ? (just an idea)
