How find the address of patches (Ace Combat 5 NTSC-J)

[mebius1]

Firstly, I apologize my poor English.
I live in Tokyo, so I have only NTSC-J version.

I'd like to play AC5 on PCSX2, but there are several bugs on NTSC-J version.
For example invisible plane and ships, cannot touch down.
So I copied patches of AC5(NTSC-U,SLUS-20851) to AC5(NTSC-J,SLPS-25418). However patches didn't work.

I think,if write the appropriate code in the GameIndex.dbf, these bugs will be fixed...

-------------------------(patches of NTSC-U)--------------------
Serial = SLUS-20851
Name = Ace Combat 5 - The Unsung War
Region = NTSC-U
Compat = 4
[patches = 39B574F0]
comment=Rearranging COP2 instructions that use old results

patch=0,EE,001A3B94,word,48498800
patch=0,EE,001A3B98,word,4B00682C
patch=0,EE,001A3BA4,word,484A8800
patch=0,EE,001A3BA8,word,4B0C682C
[/patches]

-------------------------(copied these patches to NTSC-J)--------------------
Serial = SLPS-25418
Name = Ace Combat 5 - The Unsung War
Region = NTSC-J
[patches = 86089F31]
comment=Rearranging COP2 instructions that use old results

patch=0,EE,001A3B94,word,48498800 <- this address maybe wrong ??
patch=0,EE,001A3B98,word,4B00682C <- this address maybe wrong ??
patch=0,EE,001A3BA4,word,484A8800 <- this address maybe wrong ??
patch=0,EE,001A3BA8,word,4B0C682C <- this address maybe wrong ??
[/patches]

Please let me know if anyone know...

I also played NTSC-U version, there is no problems.

if you have a single working patch, cheat, whatever of both the US and the J version one can probably port the patch to the other version. Maybe you can make a small google search on cheats for both versions and post them here. It is important that you have exactly the same cheat for both versions (as infinite life, ammo, money)

[Coornio]

You can't exchange cheats of the same game to a different region and expect it to work really. It won't work.

Guess the only thing you can do is wait until someone takes it up to try and patch it, but considering not many people play the japanese versions this may take a while.

[willkuer]

Well if there is a constant address offset between versions you can at least convert them... Most pnachs can be easily ported.

Oh, thanks willkuer-san. However, there is difference between NTSC-U and PAL...
------------------------------------(US version)---------
[patches = 39B574F0]
comment=Rearranging COP2 instructions that use old results

patch=0,EE,001A3B94,word,48498800
patch=0,EE,001A3B98,word,4B00682C
patch=0,EE,001A3BA4,word,484A8800
patch=0,EE,001A3BA8,word,4B0C682C
[/patches]
------------------------------------(PAL version)---------
[patches = 1D54FEA9]
patch=0,EE,001A3154,word,48498800 <-patch address is different
patch=0,EE,001A3158,word,4B00682C
patch=0,EE,001A3164,word,484A8800
patch=0,EE,001A3168,word,4B0C682C
[/patches]

Don't need the PAL version.. we need a normal cheat (preferably at least 2 or 3 working cheats and the same type of cheat as well) on BOTH NTSC-U and NTSC-J.

Best bet would be something like Max Score or Max Money, etc.

Sudonim made those patches by hand after he could give a look to devel logs.

I don't think it's something that hard once you know where to look

[willkuer]

Well you need to find an address which value was first unknown and later changed to 48498800. Doesn't sound that easy to me. Porting a cheat on the other side is normally very easy.

[mebius1]

Thanks for a lot of help and advice.
I struggled to find the correct address, and finally did.
