IQ... where to call this?

Code: [Select]

void NeoUpdateTextOne(int nOffset, const unsigned char byteValue);This line goes also in neorun.cpp or we have to add the driver exactly as it is in the TXT? just this doubt here XD
See ya!!!!!!
P.D. Thanks BDiamond!!!!!!!!

I only put it in neogeo.h like it says and it works fine . it never said to put it in neorun.cpp .


But this driver the extra moves to iori, kensou, terry no longer work .

Neogeo.h

You may have to change it to extern void NeoUpdateTextOne...

[FerchogtX]

Thanks IQ! worked.
BTW you can change this:

Code: [Select]


memcpy(src, dst + 0x700000, 0x100000);
memcpy(src + 0x100000, dst, 0x600000);

into this:

Code: [Select]


memcpy(src + 0x000000, dst + 0x600000, 0x100000);
memcpy(src + 0x100000, dst + 0x000000, 0x600000);

That will enable the changed moves
See ya!!!!!

Here's BDiamond's updated driver (from his RomShare post).

[James33]

Cool thanks

[Xeon]

just a little question, whats are the emulation differences between BDiamond's driver and Ferchogtx's+bms fixed code?

thanks in advance.

[iq_132]

Well, the major differences are:

BD is properly emulating most everything, the extra bits of ram, the bankswitch, the "on-the-fly" S Data of the game, etc
(the only problem is something minor causing the background to be "stuck"

Ferch and BMS's driver doesn't emulate a few of the ram areas, it kludges the S data, and the bankswitches aren't quite right.
(though this driver is gameplay-wise less buggy than BD's, it is emulation-wise a much crappier driver)

 i see thanks . know anything about the ingame differences (like new moves and stuff)?

With stuck you mean... static backgrounds? or GFX errors? or what exactly? just for know  
See ya!!!!!

[James33]

The background is the same on every stage of the game .

[BlackDiamond]

the only thing missing in my driver is the byte version of the bankswitch handler i removed because i assumed the game only using word access here (and actually, it do use byte access)
so, here is the driver as it should have remained (the fbaxxx one without commentaries)

Wow! It's perfect! Thanks again BD

[James33]

Thanks BD Now I wonder how to convert that to Mame code .

[BlackDiamond]

you should change this:

Code: [Select]

static void __fastcall kof10thWriteByteBankswitch(unsigned int sekAddress, unsigned char byteValue)
{
if (sekAddress >= 0x2FE000) {
sekAddress ^= 1;
kof10thExtraRAMB[ sekAddress & 0x1FFF] = byteValue;
if (sekAddress == 0x2FFFF0)
kof10thBankswitch(byteValue);
else if (sekAddress == 0x2FFFF8 && kof10thExtraRAMB[ sekAddress & 0x1FFE] != byteValue) {
SekMapMemory(Neo68KROM + ((byteValue & 1) ? 0x700400 : 0x000400) , 0x000400, 0x0DFFFF, SM_ROM);
}
}
}

static void __fastcall kof10thWriteWordBankswitch(unsigned int sekAddress, unsigned short wordValue)
{
if (sekAddress >= 0x2FE000) {
*(unsigned short*)(kof10thExtraRAMB + (sekAddress & 0x01FFE)) = wordValue;
if (sekAddress == 0x2FFFF0)
kof10thBankswitch(wordValue);
else if (sekAddress == 0x2FFFF8 && *(unsigned short*)(kof10thExtraRAMB + (sekAddress & 0x1FFE)) != wordValue) {
SekMapMemory(Neo68KROM + ((wordValue & 1) ? 0x700400 : 0x000400) , 0x000400, 0x0DFFFF, SM_ROM);
}
}
}into this:

Code: [Select]

static void __fastcall kof10thWriteByteBankswitch(unsigned int sekAddress, unsigned char byteValue)
{
if (sekAddress >= 0x2FE000) {
sekAddress ^= 1;
if (sekAddress == 0x2FFFF0)
kof10thBankswitch(byteValue);
else if (sekAddress == 0x2FFFF8 && kof10thExtraRAMB[ sekAddress & 0x1FFE] != byteValue) {
SekMapMemory(Neo68KROM + ((byteValue & 1) ? 0x700400 : 0x000400) , 0x000400, 0x0DFFFF, SM_ROM);
}
kof10thExtraRAMB[ sekAddress & 0x1FFF] = byteValue;
}
}

static void __fastcall kof10thWriteWordBankswitch(unsigned int sekAddress, unsigned short wordValue)
{
if (sekAddress >= 0x2FE000) {
if (sekAddress == 0x2FFFF0)
kof10thBankswitch(wordValue);
else if (sekAddress == 0x2FFFF8 && *(unsigned short*)(kof10thExtraRAMB + (sekAddress & 0x1FFE)) != wordValue) {
SekMapMemory(Neo68KROM + ((wordValue & 1) ? 0x700400 : 0x000400) , 0x000400, 0x0DFFFF, SM_ROM);
}
*(unsigned short*)(kof10thExtraRAMB + (sekAddress & 0x01FFE)) = wordValue;
}
}i just noticed this when working on fba for xbox. with the fisrt version of the code, the SekMapMemory functions are never reached.
