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

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 ;)

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 ;)

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

gcc input.c -o output

btw, yes, I can do that ;)

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 ;)

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

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.
