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
5003-c3d.bin 0x800000 0x71b3172d
5003-c4d.bin 0x800000 0x564c70c1
5003-c5d.bin 0x800000 0x8ef8aef9
5003-c6d.bin 0x800000 0x8a0fd440
5003-c7d.bin 0x800000 0x6f1effab
5003-c8d.bin 0x800000 0x39550d3a

Here's a tool to encrypt/decrypt pnyaa, mslug4, and rotd's V roms
A simple command line replacement for that crappy v2v tool

I don't know if you've all noticed, but Halrin's site has been updated.

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

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

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

iq_132 · « **Reply #8 on:** December 13, 2004, 11:17:46 PM »

I'm using the mingw compiler.
The command is this:

gcc input.c -o output

btw, yes, I can do that

here you go hotaru

Here's one

SVCCHAOS C decryption program by IQ_132 - http://neosource.1emu.net/
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)
269-c4d.bin 8mb crc(a69d523a)
269-c5d.bin 8mb crc(ba2a7892)
269-c6d.bin 8mb crc(37371ca1)
269-c7d.bin 8mb crc(56ac5fb9)
269-c8d.bin 8mb crc(de99e613)

You should also get this completely decrypted and descrambled S rom
269-s1d.bin 512kb crc(772B18DC)

btw, source is included.

thanks for the info on exe. build iq_132

hotaru · « **Reply #12 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

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

could anyone post a fixed source even though this segment isn't usable?

arigato

it would be interesting a S1 rom decrypter for all known bootlegs and original protections

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.
