Ok I'm using the lates source Mame/Mame32 0.102.

I having some problems.

I starting off on kof2003 driver.

Yes that driver is a bit old now. This is what I have, it's a rather complex driver. Firstly delete all the stuff you've put in from drivers\neogeo.c and machine\neogeo.c

Now, this goes in drivers\neogeo.c

still machine\neogeo.c, look in the neogeo_custom_memory routine,

you will see code for various games. Add this:

//-------------------------------------------------------------------------kof2003
if (!strcmp(Machine->gamedrv->name,"kof2003"))
{
 memory_install_read16_handler(0, ADDRESS_SPACE_PROGRAM, 0x2fe000, 0x2fffff, 0, 0, pvc_prot_r);
 memory_install_write16_handler(0, ADDRESS_SPACE_PROGRAM, 0x2fe000, 0x2fffff, 0, 0, pvc_prot_w);

 memory_install_read16_handler( 0, ADDRESS_SPACE_PROGRAM, 0xc00000, 0xc3ffff, 0, 0, MRA16_BANK3 );  // 256k bios
}

Now, do a clean compile and it "should" work. Good luck.

In machine\neogeo.c

look for neogeo_custom_memory and put this just before it

This one? There are few of the neogeo_custom_memory. :thumbsdown:

	/* Install custom memory handlers */
neogeo_custom_memory();

Look for this one:

**James** · November 29, 2005

Hey robbert how come you use the decrypted V rom ?

**Robert** · November 29, 2005

It's the driver I happened to find.

I just had a look and I don't possess the encrypted rom anyway.

So there's not much choice.

I'm getting an error on static.

syntax error before 'static'

Something isn't right there.

lol they do not need to be there anyway.

I have it like this myself /* kof2003 */

KillerBee · November 30, 2005

Ok I will try again. With this /* kof2003 */.

The sounds and musics are bad. Is there away to fixs those?

Edited November 30, 2005 by KillerBee

**Robert** · November 30, 2005

In what way is it bad? Does it keep repeating like an echo box, or is it all fuzzy?
