Great stuff

Now to try and do a Mame conversion .

[iq_132]

How about this James

Code: [Select]

// Decryption code by IQ_132 -- http;//neosource.1emu.net
void kof2002b_gfx_decrypt(UINT8 *src, int size)
{
int i, j;
int t[8][10] =

{ 2, 1, 0, 5, 4, 3, 6, 7, 8 },
{ 8, 0, 7, 5, 4, 3, 6, 2, 1 },
};

UINT8 *dst = malloc(0x10000);

for (i = 0; i < size; i+=0x10000)
{
memcpy(dst, src+i,0x10000);

for (j = 0; j < 0x200; j++)
{
int n = ((j % 0x40) / 8);
int ofst = BITSWAP16(j, 15, 14, 13, 12, 11, 10, 9, t[n][0], t[n][1], t[n][2],
        5, 4, 3, t[n][6], t[n][7], t[n][8]);
memcpy(src+i+ofst*128, dst+j*128, 128);
}
}
free(dst);
}

DRIVER_INIT( kof2002b )
{

kof2002b_gfx_decrypt(memory_region(REGION_GFX3), 0x4000000);
kof2002b_gfx_decrypt(memory_region(REGION_GFX1), 0x0020000);

I will give it a test . Thanks IQ


EDIT
Yep it seems to work


This is how I added it to Mame .

Hem... I have a problem here I hope that you can help me IQ (i tried to see you on Mesenger but you were away)
I have this for patching the m1 rom in kof2k2 plus as you know (or some of you know) kof2002b misses sounds (in the real cart), but in the plus versions the use a "fix" for that, so the Orochi team BGM and other stuff is fixed.
Can you help me making this code "shorter"?... this can geive a headache to the best lector XD
Thanks in advance
See ya!!!!!

[CaptainCPS]

Ok i edited the code Wheuu!! xDDD lot of code there...xDD wow 2758 lines of
patching? right? or that's not patching xD...

well now is more readable i think, and i added something missing ...that was the '' ; '' sign after
every line of code...that hurts xDD

I know IQ can do more for the code ...than i did. So i hope IQ get some time for this ^^

SeeYaa!!!
:-D

[FerchogtX]

Hem... i had another thing in mind XD... maybe a table with values or somethig like that (more or less like the svcchaos patch that was released some time ago before the real bankswitch)
Thanks anyway... but that stills big XD
See ya!!!!

[iq_132]

Tell me what crc source and changed m1, and I'll make that for you no problem

[FerchogtX]

From CRC32 AB9D360E to CRC32 (fix) F6FAB859
The last is a fix for kof2002 some time ago... but is used in the plus bootlegs so, for avoiding to use another m1 i prefer to make a table to patch it XD
Thanks in advance
See ya!!!!

[iq_132]

Here ya go.  it's only 300 lines long instead of 5000 lol

did you guys tested this code with the system configured as normal bios, mvs system and asia/euro region ? the game don't start nly in this config here... my code:

I don't see anything wrong with your driver, and I just tested mine, and it works fine with every bios tested... 
Maybe something else in your build is messed up?

[FerchogtX]

Here ya go.  it's only 300 lines long instead of 5000 lol

Thanks a lot man!!! I'll test inmedia
See ya!!!!

[Shoometsu]

if it's working with you, must be another issue from my build (I'm expect anything afther that tmnt gfx bug )

edit 28.08.o5

wow, the same code is working now, I don't know what happened... I'm thinking about to add "cursed" to my build's name
