Crouching Tiger, Hidden Dragon 2003 "C" rom decrypter

You need these C roms:

5003-c1.bin 0x800000 0x68f54b67
5003-c2.bin 0x800000 0x2f8849d5
5003-c3.bin 0x800000 0xac4aff71
5003-c4.bin 0x800000 0xafef5d66
5003-c5.bin 0x800000 0xc7c1ae50
5003-c6.bin 0x800000 0x613197f9
5003-c7.bin 0x800000 0x64ddfe0f
5003-c8.bin 0x800000 0x917a1439

You should get these Cs:

5003-c1d.bin 0x800000 0x29fd9108
5003-c2d.bin 0x800000 0xf58d4d3e

Basically, it says he's added a tool to make the correct svchaosa P roms from the svcchaos one.
The only downside is that he didn't add the source, so here's my version ;)

Quote
This program will convert:

svcchaos:
269-p1.bin CRC(432cfdfc)

to svchaosa:
269-p1.bin CRC(38e2005e)
269-p2.bin CRC(6d13797c)

thanks iq_132 :D :D btw, what program are you using to build your .exe?  i'm not savy in this arena - do you think it possible to use HalRIN's code (or some variation of) to build an .exe to decrypt 268-px.bin, 269-p1.bin, and           271-px.bin?  arigato ;)

Some source from:
Halrin - http://www52.tok2.com/home/foge/
MAME - http://www.mame.net
FBA - http://fba.emuunlim.com

you should start with these Cs (from svcchaos)
269-c1.bin 32mb crc(1b608f9c)
269-c2.bin 32mb crc(5a95f294)


you should get these Cs (from svcnd)
269-c1d.bin 8mb crc(465d473b)
269-c2d.bin 8mb crc(3eb28f78)
269-c3d.bin 8mb crc(f4d4ab2b)

Title: p_dec
Post by: hotaru on December 19, 2004, 03:03:24 pm
iq_132, the p_dec tool you posted a page back may (through no fault of your own) contain a bug in handling of 269-p1.bin.  i suspect this b/c it has given numerous different crc32 as output none of which were cited in the included text file :confused: could there be a problem w/ HalRIN's code?  off to do some testing - see what regions of 269-p1d.bin are affected.

[edit] ok, heres the skinny - the first 25165824 bytes in 269-p1d.bin contain no differences when compared to conflicting crc32 values.  the differences can be found in the remaining 8388608 bytes and amount to ~5,000,000+.  funky :p  could anyone post a fixed source even though this segment isn't usable?

arigato ;)

Well, he's a quick, slapped-together version of an s decryption tool.
Some of the decryption methods may or may not be right (I donno, haven't tested them)


@hotaru -- I'll look into it right now.

*edit*
What crc are you looking for hotaru??  The last chunk shouldn't be changed at all.

Title: IQ's neogeo Tools
Post by: iq_132 on January 20, 2005, 05:34:37 pm
lol, forgot instructions....
decrypt xxx-s1.bin x
the xxx-s1.bin can be any name and the x needs to be the decryption type.
You can check what types there are by looking at the included source.

@iq_132 - p_dec.exe seems to alter the last 8mb of 269-p1.bin, though doesn't alter the 2nd and 3rd 8mb segments.  had i checked this earlier i'd've written it off as an error - thought it to be something more :o did playmore include the last 24mb of code in this rom as garbage or are these segments used in decryption?

thanks iq_132 :)
Title: IQ's neogeo Tools
Post by: iq_132 on January 25, 2005, 03:53:02 pm
The last 3 8mb chunks are just dummy data -- garbage.  They serve no purpose.

Post by: Death Metal on March 25, 2005, 02:40:19 am
Hey IQ, I know this is very old, but I'd like to check something with you about encrypted/decrypted Vs.

We all know FBA produces internal decrypted V data from the encrypted V sets via pieces of code for each driver, from which you can get physical files using that "Save decrypted Vs" method (remember?). I've done this (extracted decrypted Vs) with all my games that use encrypted V ROMs, and then threw the encrypted ones away. However, I'd like to go back to using the official encrypted ROMs I had before, but, as it currently stands, I can't get the correct encrypted files out of the decrypted ROMs that were generated by FBA -- for example, I could use that v2v program to encrypt the ROMs I get, but the CRCs would not match the official encrypted files anymore (I've tested it).

Because of that, I'd like to know if there is a way to make an inversion of those decryption codes FBA uses. I mean, is it possible to create some code which would be the exact inversion of what it currently does, in order to encrypt V ROMs with their previously correct CRC (matching the latest Neo-Geo Logiqx dat) from the ROMs I currently have? I know I'm stupid, but I didn't think I'd want those ROMs back before I deleted them. :/

I'd be so greatful if you could help me in this. Thanks a lot.

EDIT: Oh, BTW, just to clarify, I only need to encrypt those newer PCM2 ROMs, since Metal Slug 4, Rage of the Dragons and Poochy & Nyaa have been taken care of already (with that other code that you posted here :)).

    It can process Neo-PCM2, 1999, SNK Corp. type encryption, and also
    Neo-PCM2, 2002, Playmore Corp. type encryption.



   How do I use it?
 -----------------------------------------

   If you have any questions, just run the program.  It will tell you
   what commands it supports.


   Who write this code? (Credits, please do not remove!)
 -----------------------------------------
   Most of the code for this program was written by IQ_132, but large,
   very important chunks of it were written by Fataku, Aquasync, Halrin,
   and the MAME Team.

s1grab by iq_132

This program will "grab" 512k of "S" data from the end of decrypted C roms.
You MUST use DECRYPTED C roms.  

To use the program, unzip your last two C roms (usually xxx-c7d.rom and xxx-c8d.rom) to
the same directory as s1grab.exe and then from the command line, type this:

s1grab xxx-c7d.rom xxx-c8d.rom

Please note that your file names may be different and also note that some S1 roms may require some decryption code or other processing.

   What is ptcrt?
 -----------------------------------------

    ptcrt is a tool that can batch output patch code for roms.  This is
    useful if you have a rom you know is bad, but it is the best un-hacked
    one known.  You can compare that rom with a fixed version and use
    the patches created to fix the rom "on-the-fly"



   How do I use it?
 -----------------------------------------

    If you have any questions, just run the program.  It will tell you
    what commands it supports.


   
   How about an example?
 -----------------------------------------

 Sure:

    To compare the p1 from kof2002 to kf2k2pls and get patches for fba (new):

        ptcrt F 265-p1.bin 265-p1p.bin

    To compare the p1 from kof2002 to kf2k2pls and get patches for MAME:

        ptcrt M 265-p1.bin 265-p1p.bin


   Who wrote this code? (Credits, please do not remove!)

   What is bswap8?
 -----------------------------------------

    bswap is a tool that can compare a file encrypted with a bitswap8 with a
    decrypted version of it and tell you what to use for the bitswap.



   How do I use it?
 -----------------------------------------

    If you have any questions, just run the program.  It will tell you
    what commands it supports.


   
   How about an example?
 -----------------------------------------

 Sure:

    To compare an encrypted version of the svcplus s1 rom to the decrypted version:

        bswap8 svc-s1pd.bin svc-s1p.bin


   Who wrote this code? (Credits, please do not remove!)
 -----------------------------------------

    Most of this code was written by iq_132 (me)
        http://neosource.1emu.net/

    A small, but very vital, piece comes from the FBA (Final Burn Alpha) source
   http://fba.emuunlim.com/

Make sure your SVC Chaos (home) P roms are named - 269-p1a.bin and 269-p2a.bin

   What is bswap8?
 -----------------------------------------

       bswap is a tool that can compare a file encrypted with a bitswap8 with
    a decrypted version of it and tell you what to use for the bitswap.
       You may not have to use a decrypted rom that is completely the same as
    The file you are comparing.  Different versions of files may be similar
    enought to give you correct results. (bswap8 now has the ability to give
    you the best fitting bitswap if no bitswap is a perfect match).



   How do I use it?
 -----------------------------------------

    If you have any questions, just run the program.  It will tell you
    what commands it supports.


   
   How about an example?
 -----------------------------------------

 Sure:

    To compare an encrypted version of the kof2002 "Super" s1 rom to kof2002 (265-s1d.bin) version:

        bswap8 265-s1sp.bin 265-s1d.bin

    It will also work with this:

   bswap8 265-s1d.bin 265-s1sp.bin



   Who wrote this code? (Credits, please do not remove!)
 -----------------------------------------

    Most of this code was written by iq_132 (me)
        http://neosource.1emu.net/

    A small, but very vital, piece comes from the FBA (Final Burn Alpha) source
   http://fba.emuunlim.com/



   Changelog
 -----------------------------------------


    1.0.1

   - Now gives a "best match" bitswap if no perfect one is found.
    - If a file isn't bitswapped, but is only a few bytes different, a
          diff log is created.

    1.0.0

   - Everything


I've updated the bswap8 from above. ;)

   What is cxencs1?
 -----------------------------------------

    cxencs1 allows you to take a regular S1 rom, scramble it, and split it
    so that it can easily be added to the end of the last two C roms in a
    set.  This will allow for creating hacks that have S data in the Cx
    roms as opposed to including just a S1 rom.



   How do I use it?
 -----------------------------------------

    If you have any questions, just run the program.  It will tell you
    what commands it supports.


   
   How about an example?
 -----------------------------------------

 Sure:

    To convert the S1 from kof2002, use this command:

        cxencs1 265-s1d.bin 265-c7d.bin 265-c8d.bin

    It will write the C data to the two C roms listed.


   Who wrote this code? (Credits, please do not remove!)

    Most of this code was written entirely by me, IQ_132

Title: Re: IQ's neogeo Tools
Post by: iq_132 on July 24, 2005, 04:35:51 pm
Well, it's a pretty involved process to remove a bankswitch.  I don't think I could write a tool to do it or even give you a simple way of doing it.

You need to know 68000 assembly and have quite a bit of experience with it or you can take a bootleg/hack of it with the bankswitch removed and compare the two's differences.
I did something like that for svcchaos, comparing a decrypted P1 to a bootleg with the bankswitch removed.

    This program allows you to compare two files and compare the occurances

Kany if i remember correctly (you may have been the one that told me this) but neocd loads the sprites as it needs them, i am not sure what would have to be done to the p rom to correct this so the game can run correctly, i dont think zintrick suffers from that since the sprites are small, im not sure but i think the neocd hardware can  only has 4mb of ram for sprites..  but i could also be totally wrong since i lost what info i had on the hardware :)

but anyway... using winhex for those that need a little help

mark the beginning and end of your file

ctrl+t select 16 byte swap

then to split into 2 files so it can be loaded by the mame driver select file manager and then dissect, select wordwise then save your 2 new files.  I tried to take some screen shots but they were not helpful at all :P

hope this helps... i will be out of town until monday evening, see ya later

Kany if i remember correctly (you may have been the one that told me this) but neocd loads the sprites as it needs them, i am not sure what would have to be done to the p rom to correct this so the game can run correctly, i dont think zintrick suffers from that since the sprites are small, im not sure but i think the neocd hardware can  only has 4mb of ram for sprites..  but i could also be totally wrong since i lost what info i had on the hardware :)

but anyway... using winhex for those that need a little help

mark the beginning and end of your file

ctrl+t select 16 byte swap

then to split into 2 files so it can be loaded by the mame driver select file manager and then dissect, select wordwise then save your 2 new files.  I tried to take some screen shots but they were not helpful at all :P

hope this helps... i will be out of town until monday evening, see ya later



Yep, ngcd only can load 4 mb of sprites at the same time, because ngcd only hast 4 mb of ram for that pourpose. even if it were possible, Hacking a Program rom to make diferent loads may be a pain in the ass :S.

Im still waiting someone that understand to fix the final romance 2 conversion that was released a long time ago , the program rom must be modified to avoid it hang , i think there could be some calls to bios or cd that do that. Anyone could help  :confused: :confused: :confused:

fwrite (memory_region( REGION_CPU1 ), 1, memory_region_length( REGION_CPU1 ), FP); // write program data

fclose (FP); // close the file, you must do this or your program will crash.

Just wondering....is there some way that you can do a screendump but instead of a picture, you get a grid showing the tile numbers in the particular screen positions? And, how are the c and s roms divided into each tile? And, is there a utility that shows all the possible tiles, you use left/right arrows to scroll through them, while the tile number appears above?

This program requires these files:

271-bios.bin size 262144  crc c521b5bc sha1 c9a5db63523191dedd1b39baab8772f64f09b77f

and will output these files:

271-p1c.bin  size 4194304 crc 530ecc14 sha1 812CF7E9902AF3F5E9E330B7C05C2171B139AD2B

Just put the required files in the same directory as 2k3toa.exe and run it.  The
program will even tell you the steps it is taking to create the output files.

If your rom isn't listed above, give it a try, it may work
(or not, you never know unless you try ;) ).



Make sure your p1 is named 268-p1d.bin, run ms5pcnv.exe,
and you should get these files:

rom ( name 268-p1cr.bin size 4194304 crc d0466792 sha1 880819933d997fab398f91061e9dbccb959ae8a1 )

BootCEn -- Bootleg C Encryptor

The purpose of this tool is to encrypt and decrypt bootleg roms with
scrambled (protected) graphics.  It can deal with the type of scramble
used on:

   Lansquenet 2004
   King of Gladiator
   Samurai Shodown 5 (bl)

   Crouching Tiger, Hidden Dragon 2003
   Matrimelee (bl)
   SNK vs Capcom (bl)

   King of Fighters 2002 (bl)

This program only does one rom at a time, so it's best to use a .bat
to create the roms so that you don't have to convert them one-by-one.

Here's an example:

svcboot
----------------------------------

BootCEn 2 d svc-c1.bin svc-c1d.bin
BootCEn 2 d svc-c2.bin svc-c2d.bin
BootCEn 2 d svc-c3.bin svc-c3d.bin
BootCEn 2 d svc-c4.bin svc-c4d.bin
BootCEn 2 d svc-c5.bin svc-c5d.bin
BootCEn 2 d svc-c6.bin svc-c6d.bin
BootCEn 2 d svc-c7.bin svc-c7d.bin
BootCEn 2 d svc-c8.bin svc-c8d.bin


---------------------------------------------------------------------

If you want to know more commands for this tool, simply run it.
All available commands are listed. ;)

1.1 -- Thanks to Prof. Killjoy for pointing out a bug preventing use.
    - Also, fixed a bug with outputting if a file is not present.

Post by: KaNyErO on January 04, 2006, 05:15:38 pm
Thanks iq, i would need a little tool.

It´s similar to your s descrambler tool, but you should be able to use the swap as parameter instead of a predefined table when you know the swap but not the protection, for example if i need a new swap 8 like this....

rom = BITSWAP8(rom, 0, 6, 5, 4, 3, 2, 1, 7)

the usage should be

"swap 8 0,6,5,4,3,2,1,7"

The first number should be the swap type, and the second separated by an space from the swap type and separated by , between them is the kind of moves that should be made.

This tool + bswap8 could make very easy to decrypt every new rom using the original + the encrypted, even if the swap was not programed in the tool like it was in S_decrypt

Thanks

bitswap8 is a tool to bitswap files. It can only do bitswaps of 8 bits for now.
You can encrypt and decrypt with the same commands.


Here's an example of how to use it:

bitswap8 246-v1.bin lnsq-v1.bin 0 1 5 4 3 2 6 7

Enjoy.

   What is neoconv?
 -----------------------------------------

    neoconv is a tool to encrypt/decrypt V (sample) roms for Neo-Geo.
    It can process Neo-PCM2, 1999, SNK Corp. type encryption, and also
    Neo-PCM2, 2002, Playmore Corp. type encryption.

   The games supported are:

      Metal Slug 4         (SNK Type)
      Rage of the Dragons      (SNK Type)
      King of Fighters 2002, The   (Playmore type)
      Matrimelee         (Playmore type)

      King of Fighters 2003, The   (Playmore type)
      Samurai Shodown 5 Special   (Playmore type)


   How do I use it?
 -----------------------------------------

    If you have any questions, just run the program.  It will tell you
    what commands it supports.


   Who wrote this program?
 -----------------------------------------

    Most of the code for this program was written by IQ_132, but large,
    very important chunks of it were written by or based on code by
    Fataku, Aquasync, Halrin, and El Semi.


   Changelog
 -----------------------------------------

    2.0
   Complete rewrite
   Code is much shorter and cleaner
   Decrypt/Encrypt for PCM2 Version 2 (Playmore, 2002) unified and shortened
   Decrypt/Encrypt for PCM2 Version 1 (SNK, 1999) shortened and uses less ram
   Added about section in info
   Changed some descriptions of options in the commands info

Please not that for the end user there is no real difference between this and version 1.0.  I was just very unhappy with how the code was/is and wanted to clean it up a bit.

Use SMA, programming which converts P ROMs of the games which chipsets will be possible?

Encrypting/decrypting SMA roms isn't a big deal at all.  It's a simple bitswap and rom overlay.
Simply a matter of bitswapping + moving memory chunks.

Thanks a lot iq.

Btw, i was able to convert kof2k3 to .mvs format used in dingoo, but the problem is that i dont have sound at all. I dont know why some games doesnt have it at all, and for example garou only play sounds and music with the prototype release (well that´s acording to the compatibility list) .... :S

This games are playable now in native dingoo emulator:

King of fighters 2003 (without sound)
art of fighting
Fatal fury 2
ironclad
king of gladiators
king of the monsters 2
lansquenet 2004
sengoku 2
super side kicks

I should take a look at world heroes, chtd2003  and other homebrew games and hacks (plus versions and other) , but i dont have too much time now.

Since .mvs files are in fact roms, i dont think they are allowed here, but feel free to post how to convert them.
