(adsbygoogle = window.adsbygoogle || []).push({}); ok ive gotten about 10 PM requests from people just wanting to change names so it looks like someone elses patch is there own

i dont endorse this but i will provide the knowledge since i love to share what i know with others..

altho personally i think you should have read the full tutorials all over the place, here is short version to edit names....

IM USING DD B/C PPL MSGING ME JUST WANT TO REPLACE SOMEONE NAME WITH THERE OWN Smile there that should answer most post questions so far lol


i wont give you a fish tho i will teach you to fish

download packzip and offzip and put in a directory with your patch_mp.ff

create a folder called patch

run-> cmd (opens dos prompt)

now drag offzip onto dos promt and after it type -a -z -15 patch_mp.ff patch 0

then go into your patch folder and open 00014f51.dat with a hex editor and search for dd.gsc once you find it start at the x and copy down to thru the 00 00's in hex to the FF FF FF FF

now copy this section and create a new file and paste it inside and save as dd.gsc

now use offzip again but instead of using it on patch_mp.ff use it on dd.gsc

the file it extracts is 00000002.dat open this in notepad and search for what you want to replace. replace it and then close

now create a new txt doc and rename it from new text doc.txt to ddmod.gsc

now use packzip thru dos promt and type packzip -o 0x00000002 -w -15 00000002.dat ddmod.gsc

now open up ddmod.gsc in a hex editor and you'll see the first 4 hex values as 00 00 replace these with 78 DA

now go to end of file and see what offset your on.

open up the original unmodded dd.gsc and hit control G for goto and type in the offset you see at the end of your ddmod.gsc

now copy from this point down thru the FF FF FF FF (end of file)

now paste this into the new ddmod.gsc

anything in red thats not a FF FF FF FF you should replace with 00's

now save this ddmod.gsc

open up 00014f51.dat and find the section you copied out to create the dd.gsc and highlight it

open up ddmod.gsc and highlight and copy the entire thing

go back into 00014f51.gsc and right click on selected area and hit paste write and itll replace the info with your now modded gsc

now save and go back to your command promt and type packzip -o 0x00014f51 -w -15 00014f51.dat patch_mp.ff

now copy patch to your ps3 and you are golden Smile





if you have any questions then post here, please dont flood me with pm's.

thank you and goodluck,
jeff


UPDATE I TOTALLY FORGOT TILL NOW

CHECK THE FILESIZE OF YOUR 00000002.dat after editing and copy it.

now go to google and paste it followed by "in hexadecimal"

example: 56432 in hexadecimal

now you'll get something like f64a or 10f42

now go in above dd.gsc and look for the weird y's (in hex FF FF FF FF) right b4 those is a 4 digit hex of the old filesize, replace this with your new hex google gave you

if there is a { then there should be a } to match it

if not you'll get a syntax error, also make sure anything that is supposed to end with a ; has a ; at the end of it

what all did you change?

i suggest you start small and just change 1 letter in a welcome or something so you can get the process down without worrying about 2000 different areas your issues may be coming from at once

when i edit a patch i do one thing at a time so if i have a problem i know where to look!

hope that helps

ya i just change the name like you said, thats it but i will check it again.

did you change your filesize within the main dat to the size of your 00000002.dat converted into hex via google?

yes i did and finally got it to work!!!! everyone looking to edit patch_mp this is a way to do it.
can u tell me what the file.dat is for the missions?
09-29-2010, 05:17 AM #41
missions.gsc is a bit trickier

it starts in b4a0 and ends in 14f51

you start copying in b4a0 and copy to end of file and paste into new hex file

then you start in 14f51 and copy from top down to the FF FF FF FF and paste that into the end of the file you just made

hope that helps, im glad to see people are reading my tutorial and getting things to work, if i can inspire anyone to learn to code it makes me happy Smile

btw if you enjoy doing what your doing go to school for computer science you'll have a blast Smile

ok question so now how do it split them apart to recompress them?
09-29-2010, 06:04 AM #45
you dont, you recompress them as a whole

then you copy the last 61d bytes and write it into 14f51 and the rest into b4a0 where it would belong ^_^

you piece together same as you took it apart
