[Tutorial] Hex Edit .iff files

[maumau78]

Hi All,

I received many PM on how to hex edit stuff like cloth or stadium...thanks to Greg for suggestion I'm gonna share the method:


1. Rename cloth_net.iff file to cloth_net.zip
2. Use 7-zip (http://www.7-zip.org/) and decompress the file into cloth_net folder
3. Inside the folder you'll find all the uncompressed .iff archive files (images , scene description and model files)
4. If for example you want hex edit net physics parameters (cloth file ) use a hex editor like http://www.hexworkshop.com/.....then save the file
5. Once finished just use 7-zip again and compress the files back into a .zip archive using LZMA compression



6. Rename compressed .zip file back to .iff
7. Use external file loader to load archive (or Greg explorer tool)

I know a lot of modder from past 2K are really good @ Hex Edit....hope this will help them!

Regards


EDIT: I set compression to ULTRA

can you try the global.iff??

[maumau78]

can you try the global.iff??

Well stadium too works...global I didn't try.....but it should work too

Does this mean.. you could possibly do a TNT scoreboard and change the 2k wipe??

This would be HUGE for the community. There were no scoreboard mods for last years game, a TNT scoreboard would make this game pop and add to the realism.

I'm not experienced on this kind of stuff sorry....let's wait for some other expereinced modders to reply you....

I tried todo this with the floor iffs i change the .iff to zip then use 7zp to decompress it but nothing happens for me

Ok can you explain better?

It will decompress all the iff files into a folder....

[Manni Live]

Ok this si what i did i use the fXXX.iff added it to the 7zip archive made sure its on ultra and LZMA and on 7z then i clicked ok

it made a fxxx.zip so i renamed it to fxxx.iff that was what i was suppose todo right?

no :

fxxx.iff -> fxxx.zip
then decompress with 7zip to a folder

then look inside the folder and eventually hex edit files
once finished repack with LZMA and rename to .iff

[Manni Live]

ok with this method will i be able to add files to an archive?

[TBM]

Of course not.

[Manni Live]

Of course not.

Should've been more specific i mean replace files with the same filename

[maumau78]

Of course not.

Should've been more specific i mean replace files with the same filename

yes

Hey, 1st of all thanks for this tutorial maumau, it's been really helpful! Maybe I've found something:

- In 2Z there's a roster.iff and I used your method of compression - decompression with 7zip.
- The result of this is a roster.RDAT that, guess what, it's completely readable with a hex editor; in fact it resembles in some strings to our missed rosters from previous years.

Please tell me what do you think about it.

BTW, in 2Z there's also a injuryfree_roster.iff.

Eit: it seems as if the code were aligned at some points and not in others. I'm taking a look near the beginning and I see M.i.d.d.l.e.t.o.n. k.h.r.i.s., 7 players in the middle not aligned and the next one aligned is c.o.p.e.l.a.n.d. C.h.r.i.s.. It seems the file starts with a list of players by team (76ers, bucks...), but it seems that some bit-alignment work has to be done.

[seanbarkley]

familiar?

I don't think that roster is used by the game at all. Could be wrong, but yeah.

[seanbarkley]

I know it's not the current roster, but I was trying to figure out why it was there together with a injuryfree_roster and both of them hex-readable. Advances on hex editing are not very prolific nowadays, so I'm just trying to contribute a little bit.

Really no idea on how to use it

I've actually seen that one before when maumau posted this tutorial. I changed some values but there really wasn't any changes that I can see off the bat.

I do remember modders from 2k14 who modded the roster.iff files. Still not sure what they changed there either.

[seanbarkley]

Same here, I've tried different stuff but there's no way I can see any change in the game. Same happened with some files in the shoe_global; I've edited some shoe colors but don't see the changes in the game.

BTW, was somebody able to open the SYNC.BIN file?

Hope somebody will figure this out.

decompress or unpack?? cant turn it back to an .iff file

Hey, I'm gonna post you some tips maumau has given me yesterday. It worked for me:

1. Extract the .iff to your desktop
2. Rename the .iff to .zip
3. Right click on the file --> 7zip --> extract to folder
4. Hex edit the files you want inside the folder.
5. Once done select all the files and right click on them --> 7zip --> create archive
6. In the menu select --> FORMAT: .zip compression method: LZMA
7. That will generate a .zip, just change that .zip with .iff
8. Done

[TBM]

You don't have to rename the .iff to .zip BTW.

[Kevin]

yes, opening it through winRAR is ok. No need for the renaming part.

TNT scoreboard Mod anyone?
