The normal XOR is 9d for kof2003 MVS

X-or · « **Reply #46 on:** January 17, 2005, 08:25:32 AM »

the pcb version has a specific protection
it won't use the mvs gfx key
btw you need to get the roms first, and I doubt you do am I wrong?

you're not wrong heh, thx for the info

I think kof2003 encrypted pcb c roms have almost the same protection as svcchaos c roms:
mvs xor + bitswap
But as x-or said we have to get them first xD

See ya

you forget that you cant encrypt 16mb roms using convert 2 just 8 mb max. ... there must be coded another tool to do that conversion

lol there's an easy way to verify:
take the kof2003a C roms, join c1c+c3c, and bitswap it (hexworshop can do that) and see if you get a matching crc for c1
I doubt it tho, svc protection isn't as easy as you think (mvs xor + bitswap)

Yeah i know it

Its not a simple bitswap, if u see it uses a lot of xor's to do the bitswap (something like neo-pvc code that uses xor's on bitswap), and i think c roms are interleaved too, like svcchaos...
I think we will get the fully c encrypted roms first, them we will can make a driver and a tool to encrypt it
See ya

I am sure it still uses the MVS xor plus the extra protection .

svcchaos & kof2003 PCB bios code is here,^_^.

Code: [Select]
static void PcbBiosMapHandler() { SekMapMemory(Neo68KBIOS+0x20000,0xC20000,0xC3FFFF,SM_ROM); // for PCB BIOS }

It wont compile useing this code the error is neo68kbios undeclared

do step like this:

add to neogeo.h

Code: [Select]


// neo_run.cpp
.
.
.

extern unsigned char *Neo68KBIOS; // for PCB BIOS
.
.

add to neo_run.cpp

Code: [Select]

unsigned char *Neo68KROM01, *Neo68KROM02;
unsigned char *NeoZ80ROM;

unsigned char *Neo68KBIOS; // for PCB BIOS

static unsigned char *Neo68KVectors, *NeoZ80BIOS;
// static unsigned char *Neo68KBIOS, *Neo68KVectors, *NeoZ80BIOS;

I've followed the 1st tutorial in this thread to use kof2k3 in 0.2.95.23, but I got a guru meditation if I'm using the smaller k2k3fix.cpp (~4kb). the medium and the large works fine here, but I'm really curious about what can be happening here. wich files do I have to attach to someone help on it
