Title: cthd2003 and kof10th in AES mode ?
Post by: Nsk on April 18, 2006, 09:23:16 AM

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?  :redface:

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  :smilie:

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

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

Thanks in advance for the help

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.

Post by: Nsk on April 18, 2006, 09:16:35 PM

thanks for the answer

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

Post by: KingHanco on April 20, 2006, 07:19:06 AM

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. :biggrin:

I always stick with the MVS bios.

Post by: Nsk on April 20, 2006, 10:49:29 AM

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  :smilie:

Thanks

Post by: iq_132 on April 20, 2006, 01:37:47 PM

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.

Big thanks !!
I will try it.  :smilie:

Title: Re: cthd2003 and kof10th in AES mode ?
Post by: Nsk on April 20, 2006, 07:53:13 PM

ok I try it and cthd2003 start now with the aes bios. It still being in arcade mode but start thanks  :smilie:.
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  :rolleyes:

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

Hi

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

The sources are full aivable there is a lot of adds from many others builds: enjoy  :smilie:

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).

Post by: Nsk on September 29, 2006, 06:55:11 PM

Big thanks to work on it  :wink:

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

Post by: iq_132 on September 30, 2006, 05:15:06 AM

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

I will try this thanks!

I have try this patchs  :smilie:

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 :smilie:
"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...  :rolleyes:

Big thanks for all !!  :smilie:

I'm not sure exactly you're saying here?

Kof10th unique:

Thanks for kof10uni, it works great !!

For kof10th, this is the problem with the patch:
- in aes mode: no problem now
- in arcade mode this make the game run with this setting by defaut:
(http://houba.pitufo.org/kof10th.png)
and normaly this should be:
(http://houba.pitufo.org/kf2k5uni.png)

this problem is just for kof10th, with the latest pach kf2k5uni and kof10thu (set2) work great

Just a question: how do you find this patch?

now there is only kf10thep (extra plus) who does'nt work in aes mode  :smilie:

Post by: iq_132 on October 04, 2006, 08:11:35 PM

Well, this fixes some of the dips with kof10th, I need to look more for the other ones.

     ((UINT16*)src)[0x0531656/2] = 0xEDAA; // Fix some of the DIPs

Title: Re: cthd2003 and kof10th in AES mode ?
Post by: Nsk on October 05, 2006, 04:54:46 PM

One more: Thanks  :smilie:

But it makes the game stop working, kof10th doesn't boot any more with this patch added.
Should I replace some others with this one?

Title: Re: cthd2003 and kof10th in AES mode ?
Post by: iq_132 on October 09, 2006, 12:18:51 PM

Hmm. Boots on FBA (maybe a cpu emulation bug somewhere??).
I'll take another look at it later.

Title: Re: cthd2003 and kof10th in AES mode ?
Post by: iq_132 on October 12, 2006, 08:40:27 AM

Took a look at kf10thep, this one was a pain in the ass to say the least.

kf10thep:

Code: [Select]

*((unsigned short*)(Neo68KROM + 0x000126)) = 0x0010; // Allow Region change
*((unsigned short*)(Neo68KROM + 0x000228)) = 0x4E71; // Allow System change
*((unsigned short*)(Neo68KROM + 0x00022A)) = 0x4E71;
*((unsigned short*)(Neo68KROM + 0x00022C)) = 0x4E71;
*((unsigned short*)(Neo68KROM + 0x000234)) = 0x4E71; // bne
*((unsigned short*)(Neo68KROM + 0x000236)) = 0x4E71; // bne

Kof10th

Code: [Select]

*((unsigned short*)(Neo68KROM + 0x53162C)) = 0x7425; // Fix System
*((unsigned short*)(Neo68KROM + 0x53163A)) = 0x8084; // Fix Region
*((unsigned short*)(Neo68KROM + 0x531648)) = 0x3641; // Fix some dips

Post by: Nsk on October 12, 2006, 03:47:24 PM

It works very well for kf10thep  :smilie:

For kof10th it does'nt fix any dips with mame... but not a problem, the game works very well  :biggrin:

Big thanks for all!!
