Use any of the descrambling codes in the nNeoTextROMFixType thread (case 7)

Now... the prob is that i can't get the GFX working good, i mean, i can't display correctly the whloe information of the rom, only parts, even if deleting the ALTERNATE_TEXT flag i can't get good texts... anyone got an idea to fix it?
See ya!!!!!
P.D. The init is working perfectly, maybe this is problem of the emulator since 256 KB s1's doesn't really exists, at least in non-hack sets...  
P.D.2 to get that 3 p roms: take p1sp posted by Jimmy/Santahempa thats p1sp, split cthd2003 p2 in 4 parts, delete part 1, concatenate like this:
-part 2+3 = p2sp
-part 4+p1sd CRC32 ab5c4de0 = p3sp
I don't know if that is correct, is just to try to match the real lyout of the 68 K...

[FerchogtX]

  What happened? no one has got how to fix this prob?... i played around with all of neogeo src and i got nothing... anyone knows?
See ya!!!!

[James33]

All I know is that the S rom decrypt code has no affect at all .

[fataku]

afaik this rom 5003-p1sp.bin 0x96ee06bc is scrambled, and you are missing the other 2 P scrambled roms, then have to descramble it and thats all  

[James33]

If you split the S rom 6c355ab4 into 2 you get 2 128k roms with the same CRC c5061aaf. Maybe this is the right one to work with ?

[FerchogtX]

afaik this rom 5003-p1sp.bin 0x96ee06bc is scrambled, and you are missing the other 2 P scrambled roms, then have to descramble it and thats all  

XD this time i have to say you are wrong, that rom is the fist part of a p2 rom, compare with the fist MB of cthd2003 p2 rom and you will see that they are similar, they just changed the pallete for zero and ignis (B) button color, for the other roms, you're right i'm missing tem, but no one have discovered the CRC's of the real cart... that's the reason i use this, becaus is suposed that the rom uses this lyout (or the contrary if you confirm it):
p1 = 1st MB of p2
p2 = 2nd and 3rd part of p2
p3 = 4th part of p2 and p1 rom
maybe this is wrong but noone has confirmed either this protection of the CRC's
See ya!!!!!

[FerchogtX]

Well, i tried all i know (in my short knowledge) to get that 256 KB s1 working on fba... and nothing... i think that is something in neo_text.cpp, but i don't understand anything of that file XD...
I give up XD how does mame read s1 roms? in that emu works fine  
See ya!!!!!!!

It won't work on FBA.

The FBA need to be updated inorder it to work on others arcade programs roms. It not compadable yet on FBA.

That why it won't pickup.

Just like the some of the winkawak roms won't pickup on FBA. For exsamle Bang Bead (bngbeadn) won't work on FBA.

Well, as far as i know that set works on fba, i got it working a lot of time ago, this game (ct2003sp) needs a handler for reading 256 KB roms, that's the only thing, if someone with more knowledge than me knows the answer, ct2003sp will work in FBA.
See ya!!!!!
P.D. Kawaks sets are 100% compatible with FBA, you need to read a lil' more the src, all Kawaks and nebula and mame sets are working on it.

Hmmm...

That weard.

RomCenter people at their forum told me not all the Kawaks roms aren't compatible with FBA.

I couldn't get some of those roms to work and I thought their right about that.

I shouldv'e ask you instead.

Some of those roms I get blue wires screen and I try all swaps to get to work. No luck at all.

Yes not all the CRC aren't the same thing. Different levels of same and different dumps.

Have you been to the CAESAR website yet??? There are some things that I learn from there.

Well, is hard to believe but, RomCenter people is wrong, all kawaks sets worrk on fba, im gonna explain you:
-FBA is open source, what doees this mean? that fba can be modified by its original program code or source, if you know a lil of programing or have time to read and use your intuition, you can add features to the program you are compiling, in this case FBA, so, you can add WORKING drivers into fba, and even mnore if you invest a lil' of your time and patient.

-Some games need extra configuratiosn, such as the standard fix functions (swaps), in other cases, inits, that needs to know about tha protection involved of the game to be emulated, this can vary (for example, kof2002 p2 protection, of the Neo-PVC protection or bankswitches). sometimes you van get some sets easily working, sometimes you'll need help (such the help that halrin gave to all of us releasing Neo-PVC codes).

As you can see if you want you can make run whatever you want, sometimes you'll need help (like me in this case) but if the program (or emu) is open src, this open a world of posibilities in modifying the prgram itself
See ya!!!!!
P.D. Not all that RomCenter people says is the truth, try another version of romcenter (like 2.52 or 2.60) i have that program too and I never had problems with CRC stuff

} else {

}Replace with this:

Code: [Select]

if (nNeoTextROMSize > 0x020000 && nNeoTextROMSize != 0x040000) {
if (BurnDrvGetHardwareCode() & HARDWARE_SNK_ALTERNATE_TEXT) {

} else {

}Now ct2003sp runs perfectly

That breaks suport for 128 KB extracted data from C-ROMs (at least that i did before and got probs with other games)
