Topic: cthd2003 and kof10th in AES mode ?

[Nsk]

Hello

I have a probleme with this two games (and clones) in home mode:

chd2003:
-don't start with aes bios in the the last release of Mameplus
-don't get the home mode with the neogeo_hacks de MamePlus and europe bios v2

kof10th:
-dont get home mode with the neogeo_hacks de MamePlus and europe bios v2
-dont get home mode with the aes bios

could someone help me? 

I already apply this patch (removed from mameplus sources) in machine/neoprot.c for the others games who dont past the advert. It works great

I found this here (thanks): http://neo-source.com/index.php?topic=221.0

I also have an other probleme with kof10th who only works with 2 coins slots 

Thanks in advance for the help

[iq_132]

I donno about cthd2003, but kof10th is always in MVS mode (it was hacked to be that way).
The problem with the slots is probably related to that as well.

[Nsk]

thanks for the answer

I think so but, but with the uni-bios and the cheat dat they can run fine in aes mode. 
Is there possible to had the patch in the code?

[KingHanco]

I have 1 question. Why do you want to use the non-arcade AES cart bio to use on the MVS Neo-Geo arcade games? None of those are non-arcade AES Neo-Geo games.

I always stick with the MVS bios.

[Nsk]

I have doing a AES version of MAME, and they are the only tho games that dont get the AES mode.

I search why cthd2003 doesn't start since the last versions of MAME with the AES bios.

Before cthd2003 only give the arcade mode (like kof10th) but he started and today not (the code have been splited but it's the same: I don't anderstand ??)

I know it isn't very important but if someone can help 

Thanks

[iq_132]

Ok, I figured out why cthd2003 (and it's hacks) stopped working.  In AES mode, these trigger the watchdog at some point, resetting the game & giving a black screen.

Here are some patches to fix that.

FBA:

Code: [Select]

// Fix for AES mode (stop loop that triggers watchdog)
*((unsigned short*)(Neo68KROM + 0xA2B7E)) = 0x4E71;

MAME:

Code: [Select]

// Fix for AES mode (stop loop that triggers watchdog)
mem16[0xA2B7E/2] = 0x4E71;


I'll take a look at kof10th later.

[Nsk]

Big thanks !!
I will try it. 

[Nsk]

ok I try it and cthd2003 start now with the aes bios. It still being in arcade mode but start thanks  .
For kof10th the game start with the aes bios it's not a probleme (same probleme: in arcade mode only).

This is a good fix, it's probably impossible to make this games starting in aes mode without a cheat code 

manny thanks for helping me to fix the start of cthd2003 annyway (and escuse me for my very poor english  )

Hi

thanks to your help from this post and others I finiched my build you can find it here:
http://houba.pitufo.org/

The sources are full aivable there is a lot of adds from many others builds: enjoy 
(it's a french site...  )

Looked at this a little more...

Code: [Select]

// Game sets itself to MVS & English mode, patch this out
*((unsigned short*)(Neo68KROM + 0xED00E)) = 0x4E71;
*((unsigned short*)(Neo68KROM + 0xED394)) = 0x4E71;

// Fix for AES mode (stop loop that triggers Watchdog)
*((unsigned short*)(Neo68KROM + 0xA2B7E)) = 0x4E71;

This allows AES mode without a cheat, however, the menu and a few other
things for AES mode is buggy (check kof2001 as it is buggy [unfinished?] like this also).

[Nsk]

Big thanks to work on it 

I finaly give a freeplay mode to these games. It works great

NP, as promised (a long time ago), here's a fix for kof10th

It was difficult to figure this out because the program code for it
is protected (xored) and swapped in dynamically (in the 0xe0000 range),
and it isn't a usual type of write that bootleg authors do, it sets an
address range, then moves a byte into an offset in the address range (simply).
After I realized that the code for this was in this range (thanks to Raz!),
I looked at where it was coming from (thanks again to Raz!).  I then took
a nop (4e71) and xored it by the correct values (again, Raz!) to make it
work correctly as the game was ran.

Code: [Select]

The only lines of code you really need are these two. 
The rest above are just for informational purposes.
Also, these patches DO NOT make the game fail the UNIBIOS crc check.

// FBA

Code: [Select]

  *((unsigned short*)(Neo68KROM + 0x053162C)) = 0x7425; // Fix System
  *((unsigned short*)(Neo68KROM + 0x053163A)) = 0x8084; // Fix Region

// MAME

Code: [Select]

  ((UINT16*)src)[0x053162C/2] = 0x7425; // Fix System
  ((UINT16*)src)[0x053163A/2] = 0x8084; // Fix Region

Thanks IQ

Big Thnaks!!!

I will try this thanks!

[Nsk]

I have try this patchs 

cthd2003 and clones work now in aes mode (like original kof2001 so with garbage on menu) but great: thanks!!

kof10th works great in aes mode with this patch but in arcade mode it make the game in "single play" in order to "team play" and remove the "credits watching" but it force 1coin slot so it's a very good
"team play" and "credit" could be activated in service but do you have an idea for reactivate them by default?

so this patch doesn't work with kof10th clones.

So if you know how to activate team and credit in arcade mode with kof10... 

Big thanks for all !!
