DsLazy

- Open the DSLazy application
- Select your backup ROM of GTA:CW
- Click 'NDS Unpack'
- Open the unpacked files and replace the ARM9.bin file with the one from the patch (it's not necessary to replace the ARM7.bin file)
- Click 'NDS Packer'
- Create your new modified and fixed backup

-another world
 
For CycloDS Evo you only need replace ARM9.bin. I'm not sure if replacing the ARM7.bin will cause issues, but if that is not the problem try making sure there is no pre-existing (possibly corrupt) GTA:CW .SAV file present on your microSD card. Again, I'm not certain that this is the issue but it's worth a shot to double check.

All that aside, thank you to whomever patched this. It's working fine with my CycloDS. I still think a firmware update will be the optimal solution to the incompatibility, but at least this allows us to play it.

BTW, I am impressed with the game thus far. I really didn't have high hopes for it, but so far I've been pleasantly surprised.

Thanks again.
 
AK2+AIO:
Tried the arm7+arm9 replacements, and the xdelta that was posted which should basically be the same (replaces arm7 and patches 2 bytes in arm9) - got holdups and graphics glitches all around compared to my MK5/ncard (especially when moving faster.) All that is really needed to make it work (properly) on AK2 with AIO is to change the two bytes (just like the patch) in the arm9 @ 0x100B3E on a clean dump from
00100B30 1C 26 56 43 13 AA 12 78 00 90 01 91 03 92 11 9A
to
00100B30 1C 26 56 43 13 AA 12 78 00 90 01 91 03 92 32 22
Then use Red DMA mode (the latest 03-11 loader on the aio loaders page requires you to hold X to use the old/red mode instead of the new/green mode.)

Cyclo: Someone should give this a try as well as apparently only the arm9 patch is required (which I detail above, and which ifhtt seems to confirm while I was composing this message.)

No idea why mov 0x32 into R2 makes the diff over loading the value from the stack, but kudos to whomever found the issue - it couldn't have been simple to spot

Yay for Rockstar, they always earn my sparse cash in the first play

edit:/I wonder if the mods here don't realize the full and copyrighted arm7 could be extracted from that xdelta... afaik it's just an archive of diffs and if the arm7 is fully replaced then the full arm7 is in there - kind of like a .rar without a publicly available de-archiver.

Odd other CycloDS people have gotten it to work... Can't figure out what the heck I'm doing wrong here...

Having the exact same problem.

Same problem like i listed above. I think maybe it's the fact that we are running 1.52b2.

I looked on the gba temp downloads and b3 is avalible so i'm going to try that.

If anyone could link to b4 that would be amazing, since like i said team cyclo's website is down. Blargh.
 
How to ARM9 patching so it works on EDGE/CycloDS Evolution (and some other)

- Download patch *REMOVED
- Place in a directory (lets call it "c:\gtactw")
- Copy your original scene release file in "c:\gtactw"
- Unpack "Grand_Theft_Auto_Chinatown_Wars_USA_SAVEFIX_V2_NDS-iND.zip" in "c:\gtactw"
- Start "xpa-gtac.bat"
- A new file will be generated, called "xpa-gtac-patched.nds"
- Get DSLazy (Download here)
- Unpack in "c:\gtactw"
- Start DSLazy
- Load your patched rom (xpa-gtac-patched.nds) in DSLazy
- Click NDS Unpack icon
- Copy the ARM9.bin file from the NDS_UNPACK directory to a seperate directory (lets call it c:\arm9_backup)
- Delete your NDS_UNPACK directory and current.nds
- Load original non patched GTA rom in DSLazy
- Click NDS Unpack icon
- replace your ARM9.bin from the NDS_UNPACK directory with the ARM9 from c:\arm9_backup (Overwrite original arm9.bin)
- Click on the NDS Packer icon in DSLazy
- Give a good name to it
- Copy this patched rom to your EDGE / CycloDs Evolution or R6 Xtreme, or any other card not working with Grand_Theft_Auto_Chinatown_Wars_USA_SAVEFIX_V2_NDS-iND.zip
- Done

- (Tested myself on EDGE / CycloDs Evolution and the R6 Xtreme 64G)
 
I just checked and cyclo 1.52b3 doesn't work either.

I know in b4 they added an auto patcher so that might be what's making it work, but what do i know. Like i said if anyone has a copy of 1.54b4 to link to that would be fantastic.
 
????
how do you get the arm9 patched???
I dont have a file to replace it, only arm7 file...
i am guessing that all the links were removed...
any idea where to get one?

None of the front page stuff worked for me.

I did manage to find a ARM9 file through google... I ran it through the DSLazy steps and now have a working game.

So it's definitely possible on CycloDS 1.54B2.

Good luck other Cyclo users.

you can use delta...much easier for newbies.
wifi doesnt matter because gta chinatown wars only allows chatting and those sorts

I'm using the xdelta patch. I've never used ds lazy before and frankly the though of unpacking a rom scares me.

if you look mod has REMOVED the links...

if you look again, you'll find that the links are still indeed there. are you referring to the arm7/9 ones, or the patches themselves? just use the patches, its a lot easier, and u don't even need dslazy.
 
None of the patches worked for CycloDs Evolution, No explenation given on ARM9 patching after a few asked how.

So i took the liberty to type on how to fix it for EDGE/CycloDS Evo users

Just remind, none is my work, creditz to whoever found the fix!
