Topic: NeoTextROMFix code

[FerchogtX]

If anyone needs this here the whole code I use by now...
EDIT: Fixed the code, the old one didn't do anything to the svcchaos/svcnd texts, now it's ok
in neogeo.h:
add this after // neo_run.cpp

Code: [Select]

extern int nNeoTextROMFixType;in neo_run.cpp
add this after #include "neogeo.h"

Code: [Select]

int nNeoTextROMFixType = 0; // Text fix for games that have TextBankswitchfind:

Code: [Select]

nNeoTextROMFixTypeif you have the old names...
See ya!!!!!!!
P.D. here a reference for the values:
1 is for kf2k1pla
2 is for svcboot, svcplusa, ms5plusa
3 is for ms5plus, kof2003b, svcplus, samsh5bl, kf97plsa
4 is for games that uses a 512 KB s1 rom to simulate certain effects, this is not realy a valid init, when we can get working kof2003 (PCB) and svcchaos and clones, this will be deleted, games that uses this value: svcboota, svcplusb, svcsplsa, kof2k3ba, kof2k4xa.
5 is for svcsplus, kof2k3up (thanks james33)
6 is for svcnd

[James33]

5 should also work for King of Fighters 2004 ultra Plus

[Xeon]

okay thanks peeps, time to update code

[Accosta_m]

Very Thanks Fercho  

[Shoometsu]

Don't forget to replace all nTextBankswitch references with this new name:

Code:

Code: [Select]

nNeoTextROMFixType

Where do I find these references

 

[iq_132]

He means that if you have the old "nTextBankswitch" code in your build, go through your source files and do a "search and replace" -- replacing "nTextBankswitch" with "nNeoTextROMFixType"

If you don't have the nTextBankswitch code in your build, don't worry about it

[Shoometsu]

I've discovered that I don't have this (thanks ultraedit32), search in each file for that should be a pain in the behind, no one reference to nTextBankswitch in any file here XD

one more thing: in the explanation begining where

find in neo_run.cpp:

Code: [Select]

int NeoSRAMProtection = -1;
I've found only

Code: [Select]

int nNeoSRAMProtection = -1;
I don't know if I'm doing something wrog, but " did the compilation without any error messages.

[James33]

Good old Notepad does the job for me .

[Shoometsu]

Good old Notepad does the job for me .

Sure, i like notepad too, but I don't know where could be the reference, so utraedit searched in each source file by itself, I didn't need to open each file in notepad XD lot of time saved

[FerchogtX]

Don't forget that Ultra Edit adds auto spaces when needed... very usefull
Better to use UE... you can also undo some things that you do if are wrong...
See ya!!!!!
P.D. and adds colors like the Visual Studio editor XD

[FerchogtX]

Add this after the case 5:
for ct2003sp s1 ROM

Code: [Select]

if (nNeoTextROMFixType = 7) {
unsigned char *rom = NeoTextROM+0x20000;
unsigned char *buf = (unsigned char*)malloc( 0x40000 );
int i, ofst;

memcpy( buf, rom, 0x40000 );

for( i = 0; i < 0x40000; i++ ){
ofst = BITSWAP24( (i & 0x1ffff),23,22,21,20,19,18,17,3,
0,1,4,2,13,14,16,15,5,6,11,10,9,8,7,12 );
ofst += (i >> 17) << 17;
rom[ i ] = buf[ ofst ];
}

memcpy( buf, rom, 0x40000 );

memcpy( &rom[ 0x08000 ], &buf[ 0x10000 ], 0x8000 );
memcpy( &rom[ 0x10000 ], &buf[ 0x08000 ], 0x8000 );
memcpy( &rom[ 0x28000 ], &buf[ 0x30000 ], 0x8000 );
memcpy( &rom[ 0x30000 ], &buf[ 0x28000 ], 0x8000 );

free( buf );
}maybe this works, i had to remove all not declared functions on it, to see the original driver check on the HalRin page
See ya!!!!!!

[fataku]

i thought the code was easiest, something like this:

Code: [Select]

if (nNeoTextROMFixType = 7) {
        // thanks to dorriGa and arnoldso for analyze the scramble
        unsigned char *rom = NeoTextROM+0x20000;
        unsigned char *buf = (unsigned char*)malloc( 0x40000 );
        int i, j;

        for (i=0;i<0x40000;i++){
            j=BITSWAP24(i,23,22,21,20,19,18,17,9,8,10,11,0,5,4,3,2,1,6,7,13,16,12,14,15);
            buf[j]=rom[i];
        }
memcpy( rom, buf, 0x40000 );
free( buf );
}
and yeah a code for mame too:

Code: [Select]

static void cthd2k3s1spls(void)
{
// thanks to dorriGa and arnoldso for analyze the scramble
UINT8 *src = (memory_region(REGION_GFX1));
UINT8 *dst = (UINT8*)malloc(0x40000);
int i,j;
for (i=0;i<0x40000;i++){
j=BITSWAP24(i,23,22,21,20,19,18,17,9,8,10,11,0,5,4,3,2,1,6,7,13,16,12,14,15);
dst[j]=src[i];
}
memcpy(src,dst,0x40000);
}

memcpy(src,dst,0x40000);

ct2003sp extract the s data from the end of c roms? I don't know if i add this before the 6th or the 5th option according to the extraction (or not)
 

[James33]

No thats meant to descramble the S rom .

[Shoometsu]

No thats meant to descramble the S rom .

Code: [Select]



NeoTextROM = (unsigned char*)malloc(nNeoTextROMSize + 0x020000);
if (NeoTextROM == NULL) {
return 1;

                options 1 to 5 here

        } else {
// Extract data from the end of C ROMS
BurnUpdateProgress(0.0, "Gerando gráficos de texto ", 0);
NeoExtractSData(NeoSpriteROM, NeoTextROM + 0x020000, nSpriteSize, nNeoTextROMSize);

                option 6 here


 where do I insert the 7th option? with the other 5 or with the 6th in thi "if" structure?
