Author Topic: Post 2002 Neo Geo drivers, questions (Read 21415 times)

DethXec · « **on:** March 02, 2005, 05:39:44 AM »

Well, since I didn't have much time to keep updating the fba drivers, I'd like to know the state of the drivers... It really will take me a long time to search and check once and again, because most of the drivers were updated some how, and now the FBA source has another way to load the PCM2 and stuff...

So, in short, what's going on with:

· Pochi and Nyaa
· KOF 2003 (two versions, so two drivers)
· Samurai Shodown V (two dumps, so two drivers)
· Samurai Shodown V Special
· SNK Vs. Capcom SVC Chaos (two versions, so two drivers)

Thanks a lot for any little infos...

all working, but you need proper bankswitching to pcb protections code found in http://neo-source.com/index.php?topic=299.0

to kof2003 you'll also need the k2k3fix.cpp ( http://neo-source.com/index.php?topic=217.0 ), get only this here, the rest is outdated, use the drivers from the 1st link.

to svc you'll need some c decryption code ( http://neo-source.com/index.php?topic=212.15 ) download it from the 4th post

iq_132 · « **Reply #3 on:** March 02, 2005, 06:37:05 AM »

Actually, with kof2003, the only thing you DON'T need is the k2k3fix.cpp.
I'll post some updated fba drivers for svc and kof2k3 later

no need for k2k3fix.ccp and all the steps in the "howto"? so i'll only need the bankswitches, bioses and drivers listed in the topico about "some pvc bankswitch code" cool XD

I made all the updates and changes exactly as instructed in your zip, but I got an error during compilation in Cygwin:

I figured out the problem. Your instructions say to "place this after" when it should read: "replace with this".

Everything else seems to work now. Thanks!

iq_132 · « **Reply #10 on:** March 18, 2005, 08:23:23 AM »

K, thx for the bug report

I'll fix that asap.

FerchogtX · « **Reply #11 on:** March 18, 2005, 09:40:46 PM »

Fpound the problem, just:
Look for all of this:

Code: [Select]

void NeoExtractSData(unsigned char* rom, unsigned char* sdata, int rom_size, int sdata_size)
{
	/* the S data comes from the end fo the C data */
	rom += rom_size - sdata_size;

	for (int i = 0; i < sdata_size; i++) {
		sdata[i] = rom[(i & ~0x1F) + ((i & 7) << 2) + ((~i & 8) >> 2) + ((i & 0x10) >> 4)];
	}
}

void NeoExtractSData(unsigned char* rom, unsigned char* sdata, int rom_size, int sdata_size)
{
	int i;
	if (sdata_size != 0x100000)
	{	
		rom += rom_size - sdata_size;
		for (i = 0; i < sdata_size; i++) {
			sdata[i] = rom[(i & ~0x1F) + ((i & 7) << 2) + ((~i & 8) >> 2) + ((i & 0x10) >> 4)];
 		}
	} else {
		rom += rom_size - sdata_size /2; 
		for (i = 0; i < sdata_size / 2; i++) {
			sdata[i + 0] = rom[(i & ~0x1F) + ((i & 7) << 2) + ((~i & 8) >> 2) + ((i & 0x10) >> 4) - 0x1000000 ];
			sdata[i + sdata_size / 2] = rom[(i & ~0x1F) + ((i & 7) << 2) + ((~i & 8) >> 2) + ((i & 0x10) >> 4)];
 		}
	}
}

i suppose that you have thgis like this... replace ALL with just this:

Code: [Select]

void NeoExtractSData(unsigned char* rom, unsigned char* sdata, int rom_size, int sdata_size)
{
	int i;
	if (sdata_size != 0x100000)
	{	
		rom += rom_size - sdata_size;
		for (i = 0; i < sdata_size; i++) {
			sdata[i] = rom[(i & ~0x1F) + ((i & 7) << 2) + ((~i & 8) >> 2) + ((i & 0x10) >> 4)];
 		}
	} else {
		rom += rom_size - sdata_size /2; 
		for (i = 0; i < sdata_size / 2; i++) {
			sdata[i + 0] = rom[(i & ~0x1F) + ((i & 7) << 2) + ((~i & 8) >> 2) + ((i & 0x10) >> 4) - 0x1000000 ];
			sdata[i + sdata_size / 2] = rom[(i & ~0x1F) + ((i & 7) << 2) + ((~i & 8) >> 2) + ((i & 0x10) >> 4)];
 		}
	}
}

this should fix your problem, in other words, you have twice the NeoExtractSdata, just delete the old function and replace with the new one that IQ_132 mention in changes.htm
See ya!!!!!!

P.D. THANKS A LOT IQ!!!!!!, i finally fixed a lot of bugs with this XD, really thanks. (i had probs with reset even with the clean compile XD, now that is fixed)

Hem... i have a weird question: did anyone with more than 64 or 128 MB of RAM tried to save decrypted C-ROMs of svcchaos from the "Save decrypted C-ROMs after loading" option in Kawaks dev?... if yes, who can tell me how many C-ROMs does k-dev save? 2 C-ROMs of 32 MB each? (like the encripted ones but decrypted) or 8 C-ROMs of 8 MB? I know is a weird question but is just for solving some doubts... anyone can tell me how many decrypted C-ROMs does k-dev save after loading svcchaos?
Thanks in advace
See ya!!!!!!

Ferchog, if you go back and read my replies, you'll see I already figured that out for myself. No need to have posted all that code like that.

Hey IQ_132, no samsho 5 drivers in that list? I have several rom packs from the mame set for it. Was wondering if you had coded drivers for them yet.
