Kof2003b Now Working On Fba

[Prican25]

some good news for anyone that rather uses the kawaks 1.48dev version of kof2003 (not the PCB version), ferchogtx of romshare recently posted a driver that works with that version in fba.

 

i tried to do this for fba-xxx but its different in the neo_run.cpp part and all i got was errors

 

heres the info:

in neogeo.h:

in // neo_run.ccp definitions:

extern int nTextBankswitch;

 

in neorun.ccp:

search for this:

int nNeoSRAMProtection = -1;

 

put this bellow:

int nTextBankswitch = -1; // Text fix for kof2003b and ms5plus

 

serach for this:

// Load Text layer tiledata
{
 // Load boardROM data
 BurnLoadRom(NeoTextROM,	0x00080 + 0x14, 1);

 if (pInfo->nTextOffset != -1) {
 	// Load S ROM data
 	BurnLoadRom(NeoTextROM + 0x020000, pInfo->nTextOffset, 1);
 } else {
 	// Extract data from the end of C ROMS
 	BurnUpdateProgress(0.0, "Generating text layer graphics...", 0);
 	NeoExtractSData(NeoSpriteROM, NeoTextROM + 0x020000, nSpriteSize, nNeoTextROMSize);
 }
 
}

 

replace with this:

// Load Text layer tiledata
{
 // Load boardROM data
 BurnLoadRom(NeoTextROM,	0x00080 + 0x14, 1);

 if (pInfo->nTextOffset != -1) {
 	// Load S ROM data
 	BurnLoadRom(NeoTextROM + 0x020000, pInfo->nTextOffset, 1);

 /* Original code from mame traduced by FerchogtX */
 /* Thanks also to HappyASR for the info */
 if (nTextBankswitch == 1) {
 	unsigned char* dst = (unsigned char*)malloc(0x20000);
 	unsigned char* roms1 = NeoTextROM+0x20000;
 	if ( dst )
 	{
   memcpy(dst,roms1,0x20000);
   // descrambling the S1 by dorriGa
   for ( int j=0;j<0x20000; j+=0x000010)
   {
   	memcpy( roms1+j, dst+j+0x000008,8);
   	memcpy( roms1+j+0x000008, dst+j,8);
   }
 	}
 	free( dst );
 }

 } else {
 	// Extract data from the end of C ROMS
 	BurnUpdateProgress(0.0, "Generating text layer graphics...", 0);
 	NeoExtractSData(NeoSpriteROM, NeoTextROM + 0x020000, nSpriteSize, nNeoTextROMSize);
 }
 
}

 

search for this:

int NeoExit()

 

in the neoexit function, below to nNeoSRAMProtection = -1; paste this:

nTextBankswitch = -1; // Turns off textfix when you quit a game

 

don't forget also:

if ((BurnDrvGetHardwareCode() & HARDWARE_SNK_CONTROLMASK) != HARDWARE_SNK_GAMBLING) {
   	//// added
   	if (!(BurnDrvGetHardwareCode() & HARDWARE_SNK_NEWBANKSYSTEM)) {
   	////end
     nNeo68KROMBank = -1U;
     Bankswitch(0);
   	//// added
   	}
   	////end
   }
 }

 

and this in neogeo.h:

#define HARDWARE_SNK_NEWBANKSYSTEM 0x0200

 

this will fix text layers in kof2003b ans also ms5plus, just put this line in ms5plus init:

nTextBankswitch=1;
