Post by: iq_132 on September 16, 2005, 01:34:12 AM

Here's a port of BMS888's fantastic pvc bankswitch code.

Code: [Select]

}

// These perform some palette calculations
// Unpack palette word to RGB dword
void pvc_prot1( void ) // on writes to e0/e1
{
unsigned char b1, b2;
b1 = pvc_r8(0x1fe1);
b2 = pvc_r8(0x1fe0);

Had a question about kf2k4ex, ms5plus, and mslug5b

ms5plus bankswitch

Code: [Select]

// Credits to neoaethyr
static WRITE16_HANDLER ( mslug5p_bankswitch_w ) /* Bootleg, Plus */
{
if (offset == 2)
{
neogeo_set_cpu1_second_bank(data<<16);
}
}

// put this in the ms5plus init

Code: [Select]


memory_install_write16_handler(0, ADDRESS_SPACE_PROGRAM, 0x2ffff0, 0x2fffff, 0, 0, mslug5p_bankswitch_w);



for mslug5b, just swap the second and third meg of the P rom

Not tested (I'm not at my pc right now) but it should work...

Code: [Select]

DRIVER_INIT( mslug5b )
{
UINT8 *src = memory_region(REGION_CPU1);
UINT8 *dst = malloc(0x100000);
if (dst)
{

memcpy (dst + 0x000000, src + 0x300000, 0x100000);
memcpy (src + 0x300000, src + 0x200000, 0x100000);
memcpy (src + 0x200000, dst + 0x000000, 0x100000);

free (dst);
}

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);

init_neogeo();

Thx iq but I want to know about the load rom driver data too :P
Which roms I do need to added that game to mame...

Post by: iq_132 on September 21, 2005, 01:46:19 PM

Look in the old mslug5 emulation infos thread at romshare.  The bootleg is the original rom released.  The romdata should be there.

Do you have driver for The King of Fighters 2004 - EX - Hero ?

This might work (If it doesn't let me know ;))

Code: [Select]

static WRITE16_HANDLER( kf2k4ex_prot_w )
{
UINT32 bankaddress;
COMBINE_DATA( &CartRAM[ offset ] );
bankaddress = CartRAM[0]|(CartRAM[1]<<8);
neogeo_set_cpu1_second_bank(bankaddress+0x100000);
}


Code: [Select]

memory_install_read16_handler(0, ADDRESS_SPACE_PROGRAM, 0x2ffff0, 0x2fffff, 0, 0, pvc_prot_r);
memory_install_write16_handler(0, ADDRESS_SPACE_PROGRAM, 0x2ffff0, 0x2fffff, 0, 0, kf2k4ex_prot_w);

I haven't been able to port that quite yet, there's something that keeps glitching up, and I can't quite track it down ^^

Hmmm... I gotting a lots of errors Robert.

I redone this.

Code: [Select]

if (!strcmp(Machine->gamedrv->name,"svcchaos") || !strcmp(Machine->gamedrv->name,"svchaosa"))
/*  Not in use yet and save. -  !strcmp(Machine->gamedrv->name,"svcboot") || !strcmp(Machine->gamedrv->name,"svcsplus")) */

                memory_install_write16_handler(0, ADDRESS_SPACE_PROGRAM, 0x2fe000, 0x2fffff, 0, 0, pvc_prot_w);
        }
My fixs works.  :biggrin:

How come I get errors on using this then?

Code: [Select]

//-------------------------------------------------------------------------most svc versions
if (!strcmp(Machine->gamedrv->name,"svcchaos") ||
!strcmp(Machine->gamedrv->name,"svchaosa") ||
!strcmp(Machine->gamedrv->name,"svcboot") ||
!strcmp(Machine->gamedrv->name,"svcsplus"))
{
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);
}
After that I fixs it then the errors went away. It so weard.

It should be this bellow.

Code: [Select]

//-------------------------------------------------------------------------most svc versions
if (!strcmp(Machine->gamedrv->name,"svcchaos") || !strcmp(Machine->gamedrv->name,"svchaosa") || !strcmp(Machine->gamedrv->name,"svcboot") || !strcmp(Machine->gamedrv->name,"svcsplus"))
{
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);
}
Other wise it looking for the missing extra ) that cause over 10 errors showing.

Have another look here for exsample. This is correct bellow.

   

Code: [Select]

if (!strcmp(Machine->gamedrv->name,"kof99") || !strcmp(Machine->gamedrv->name,"kof99a") || !strcmp(Machine->gamedrv->name,"kof99e"))
{
/* special ROM banking handler */
memory_install_write16_handler(0, ADDRESS_SPACE_PROGRAM, 0x2ffff0, 0x2ffff1, 0, 0, kof99_bankswitch_w);

/* additional protection */
memory_install_read16_handler(0, ADDRESS_SPACE_PROGRAM, 0x2fe446, 0x2fe447, 0, 0, prot_9a37_r);
}
See the )) at the end? If those aren't on the same line then everyone of those need a )) at the end.

Like this one bellow.

   

Code: [Select]

if (!strcmp(Machine->gamedrv->name,"garou"))
{
/* special ROM banking handler */
memory_install_write16_handler(0, ADDRESS_SPACE_PROGRAM, 0x2fffc0, 0x2fffc1, 0, 0, garou_bankswitch_w);

/* additional protection */
memory_install_read16_handler(0, ADDRESS_SPACE_PROGRAM, 0x2fe446, 0x2fe447, 0, 0, prot_9a37_r);
}
You saying that it doesn't matter then take a look in the machine/neogeo.c. You not find anything look like this bellow. Because this is wrong and will get the errors just like I did earlyer.

Code: [Select]

//-------------------------------------------------------------------------most svc versions
if (!strcmp(Machine->gamedrv->name,"svcchaos") ||
!strcmp(Machine->gamedrv->name,"svchaosa") ||
!strcmp(Machine->gamedrv->name,"svcboot") ||
!strcmp(Machine->gamedrv->name,"svcsplus"))
{
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);
}

RE: Even the offical mame code is like that in machine\neogeo.c

No it not. I check on Mame Plus NeoGeo source and the Mame NeoGeo source.

Only in the Mame Plus does that the way. The way you and Robert does it.

Download the offical Mame source. You will see the differents between the Mame Plus NeoGeo source and the Mame NeoGeo source.

Mame Plus over writes the Mame NeoGeo source. A little different coding Mame Plus uses. Beside it got hacks coding which the Mame NeoGeo source doesn't have which are not on the same page.

Anyway I don't make Mame Plus and don't uses the Mame Plus source.

Why do you think that I have so many problems? Because I don't use the Mame Plus and source.  :biggrin:

Hanco - if you think my code causes errors maybe I shouldn't provide any more help to you! The code works fine for me.

Well I fixs some other places other than the one that I post fixs. Just minder fixes and not a whole thing which you guys been helping me on. For exsample bellow.

Code: [Select]

ROMREGION_SOUNDONLY doesn't work.

GAMEB( 1992, androdun, neogeo,   neogeo, neogeo, neogeo,  neogeo,   ROT0, "Visco", "Andro Dunos" ) doesn't work.

osd_malloc doesn't work.

Even the one bellow doesn't work.

if (!strcmp(Machine->gamedrv->name,"svcchaos") ||
!strcmp(Machine->gamedrv->name,"svchaosa") ||
!strcmp(Machine->gamedrv->name,"svcboot") ||
!strcmp(Machine->gamedrv->name,"svcsplus"))

data16_t doesn't work.
You guys seem that don't know what all the errors because I can't post the snapshots anymore. iq_132 have me disabled where I can't post any. I had to do alot of fixing. Without the snapshot then it pointless to tell you. I'm  using the Mame 0.102 source only.

The code format I posted is more or less the same as the offical source . I am talking about the offical mame not mame plus or any other non offical build

I suggest you check the original Mame source  Not Mame Plus or any other source

When you get errors on your compile you should always post the errors here so then we should be able to help you .
Do not go telling us that the code is wrong when we know its not .  The codes we have posted here work in our builds so the problem is with what you doing when you add the code to your source .

James, your code for svcplusa - I didn't have this at all - not sure of its importance, but I've taken a note of it should it be needed later.

Since that code does not have a bankswitch you are able to get a decrypted P rom .

Both works fine here. The graphics, musics and sounds.

Yes.

Ok maybe I did something wrong then. Sorry.

That reply was not for you !

Quote from: Robert on December 01, 2005, 06:54:54 PM

After looking around, I do have that code, but it's a patch routine in source\neogeo.c... just another way of getting the same result.

Yes I know that .  But like I said it allows you to decrypt the P rom where the other code does not .


Oh yes does your player select screen look like this for svcsplus ?
