[fernando2]

Here ya go.

hi ! iq_32. could you make a tool to change file
 format spr (neogeocd) from 16mb into 2 files format .
rom (neogeo) of 8 mb each ?

Thanks!

Thanks!

you can do it by yourself with winhex

first do a byteswap 16
then do a disect file wordwise 16 bits and voila...

[rock23]

It does not work
continuous badly the tiles

Kany if i remember correctly (you may have been the one that told me this) but neocd loads the sprites as it needs them, i am not sure what would have to be done to the p rom to correct this so the game can run correctly, i dont think zintrick suffers from that since the sprites are small, im not sure but i think the neocd hardware can  only has 4mb of ram for sprites..  but i could also be totally wrong since i lost what info i had on the hardware

but anyway... using winhex for those that need a little help

mark the beginning and end of your file

ctrl+t select 16 byte swap

then to split into 2 files so it can be loaded by the mame driver select file manager and then dissect, select wordwise then save your 2 new files.  I tried to take some screen shots but they were not helpful at all

hope this helps... i will be out of town until monday evening, see ya later

Yep, ngcd only can load 4 mb of sprites at the same time, because ngcd only hast 4 mb of ram for that pourpose. even if it were possible, Hacking a Program rom to make diferent loads may be a pain in the ass .

Im still waiting someone that understand to fix the final romance 2 conversion that was released a long time ago , the program rom must be modified to avoid it hang , i think there could be some calls to bios or cd that do that. Anyone could help

hi iq_132 do you have a source to decrypt kf10thep?

could you post it here?

thanks for your help

bye

thanks robber but im not sure how that will help to fix the fr2 conversion to aes/mvs

Sure, here you go.

[iq_132]

FILE *FP; // define FP

FP = fopen ("output.bin", "wb"); // define file name and what to do with it

fwrite (memory_region( REGION_CPU1 ), 1, memory_region_length( REGION_CPU1 ), FP); // write program data

fclose (FP); // close the file, you must do this or your program will crash.

[iq_132]

lol, np

[James33]

These are IQ's codes in use .

Code: [Select]

/* Rom decrypt codes */
static void save_dec_p(void)
{
FILE* PROM = fopen("xxx_p_bin", "wb");
if (PROM) {
fwrite(memory_region(REGION_CPU1), 1, memory_region_length(REGION_CPU1), PROM);
fclose(PROM);
}
}

static void save_dec_s(void)
{
FILE* SROM = fopen("xxx_s_bin", "wb");
if (SROM) {
fwrite(memory_region(REGION_GFX1), 1, memory_region_length(REGION_GFX1), SROM);
fclose(SROM);
}
}

static void save_dec_vs(void)
{
FILE* V1ROM = fopen("xxx_v1d.bin", "wb");
if (V1ROM) {
fwrite(memory_region(REGION_SOUND1), 1, 0x800000, V1ROM);
fclose(V1ROM);
}
FILE* V2ROM = fopen("xxx_v2d.bin", "wb");
if (V2ROM) {
fwrite(memory_region(REGION_SOUND1)+0x800000, 1, 0x800000, V2ROM);
fclose(V2ROM);
}
}

This program requires these files:

271-p1.bin   size 4194304 crc b9da070c sha1 1a26325af142a4dd221c336061761468598c4634
271-p2.bin   size 4194304 crc da3118c4 sha1 582e4f44f03276adecb7b2848d3b96bf6da57f1e
271-bios.bin size 262144  crc c521b5bc sha1 c9a5db63523191dedd1b39baab8772f64f09b77f

and will output these files:

271-p1c.bin  size 4194304 crc 530ecc14 sha1 812CF7E9902AF3F5E9E330B7C05C2171B139AD2B
271-p2c.bin  size 4194304 crc fd568da9 sha1 46364906A1E81DC251117E91A1A7B43AF1373ADA


Just put the required files in the same directory as 2k3toa.exe and run it.  The
program will even tell you the steps it is taking to create the output files.
