Topic: SVC Chaos driver infos.

[PRican25]

ok, i just tried using the svcchaos drivers iq_132 posted on page 5 and done everything need but when compiling i get an error dealing with kof2003bMapHandlder:

Code: [Select]

src/burn/neogeo/d_neogeo.cpp: In function `int svcchaosInit()':

make: *** [d_neogeo.o] Error 1
i used the same kof2003b driver that the txt file refer to which is located here: http://neosource.1emu.net/pages/games/fba/kof2003b.htm

and i did name all occurances of kof2003 to kof2003b so i'm lost on what exactly is wrong

[Accosta_m]

you need change the references name of the Kof2003 to kof2003b

for example

this is the original code

static struct BurnRomInfo kof2003RomDesc[] = {


static struct BurnRomInfo kof2003bRomDesc[] =

this is the change do you need in your driver

[PRican25]

and i did name all occurances of kof2003 to kof2003b so i'm lost on what exactly is wrong

you missed that part of my last post

also you can see in my qoute that error was for kof2003bMapHandler

Update: i found the problem with that error as i had the kof2003b driver after svcchaos thx to james help  but now it seems i have a bigger prob as all i get from trying svcchaos set is this:

i thought i might add my neogeo files for fba, i haven't really touched fba since samsho5 based on the dev emu was playable so if you can plz fix mine or post updated files thank you

[PRican25]

did anyone have any luck finding out what might cause this? i tried another source but it too was only updated around samsho5 based on dev and got the same result after adding what was needed

Have you look at this website? http://neosource.1emu.net/

I don't have the roms to try yet.

I will find those soon anyway.

[PRican25]

well odd enough when i clicked on games and then on svcchaos it said it wasn't availible

none the less the info is posted here and thats what i used but i'm getting no such luck with it.

Update: i got it working as i notice a missing part from the textrom fix code

[PRican25]

ok, decided to stick with the old fba src for online gaming and i was trying out all the svc drivers but svchaosa for some reason gives me static sound

heres the driver i used:

Code: [Select]

Can somebody please tell me which code is required to get sound from the svcboot V ROMs? Thankies ^_^

[Vorador]

Anyone has a COMPLETE driver (with the C-roms code) for the lastest fba version)

[LikkleBaer]

Thankies alot netbug!  ^_^

[iq_132]

Well, some svcboot/cthd2003 C decryption code has been released.
Here's my version of that code (a bit trimmed)

Code: [Select]

static void DoPerm(int game)
{
unsigned char *src = NeoSpriteROM;
unsigned char *dst = (unsigned char*)malloc(0x800);

for(int i=0; i<0x8000; i++)
{
unsigned int tbl[8][16] =
{
{1,2,3,0,0,4,4,5,1,2,3,0,0,4,4,5},      // cthd2003
{1,2,1,2,3,0,3,0,0,4,0,4,4,5,4,5},      // svcboot
{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15},
{0,2,4,6,8,10,12,14,1,3,5,7,9,11,13,15},
{0,4,8,12,1,5,9,13,2,6,10,14,3,7,11,15},
{0,8,1,9,2,10,3,11,4,12,5,13,6,14,7,15},
{0,8,4,12,2,10,6,14,1,9,5,13,3,11,7,15},
{0,2,8,10,4,6,12,14,1,3,9,11,5,7,13,15},
};

int ofst=tbl[0][(i>>5)&0xF];
if (game==1) ofst=tbl[1][(i>>4)&0xF];

for(int j=0; j<16; j++)
{
memcpy(dst+j*128, src+i*0x800+(tbl[ofst+2][j]*128), 128);
}
memcpy(src+i*0x800, dst, 0x800);
}
free(dst);
}

[bms888]

Well done. IQ,this code is very short.^_^

[iq_132]

Oopsie! I left a piece of code in there that isn't needed.
Check my post above for a fixed version.

OK, we can remove all svcboot_cx_decrypt and cthd2003_c now,^_^.

This is my useing code,can keep cthd2003,svcboot,matrimbl working.^_^

neogeo.h

Code: [Select]


// d_neogeo.cpp
extern void DoPerm(int game); // for cthd2003 & svcboot C-ROMs


neo_run.cpp

Code: [Select]


// Descramble C roms without messing out the text layers (matrimbl only)
if (!strcmp(BurnDrvGetTextA(DRV_NAME), "matrimbl")) {
DoPerm(0);
}


d_neogeo.cpp

Code: [Select]
