Since on my old blog, cupevampe.blogspot.com, the most read post was this small tutorial about patching DS roms, I am copying it an pasting here, because it makes more sense to have my traffic directed here. So, without further ado, here it is…
Maybe you have a Nintedo DS ROM… maybe you also have an R4 or DS-X cart for your DS… and maybe you have noticed some games (like the latest worms or zelda) do not work with your cart, showing an error message when you load them.
Here is how to make those game work (you will need a windows computer or a mac/linuxcomputer with a virtualization software such as Parallels.
1: Click here:

to download the arm7.bin file, we will need it later.

3. Unzip this program (DSLazy) and open it.
4. Load the ROM into DSLazy (by clicking on the grey square on the left side of the software’s window.

5. Click on “nds unpack“

6. A folder called NDS_UNPACK will open.
Copy your previously downloaded ARM7.BIN file into this folder.
Copy your previously downloaded ARM7.BIN file into this folder.

7. Close the folder and select “nds packer” to rebuild your rom.
I usually add and “_patch” suffix to the name of my patched rom, you can overwrite your original rom if you want, although i dont recommend it in case anything goes wrong.

8. Copy it to your cart… it should now work!



It didnt work, the DSlazy software is screwed.
When I try to open it on my XP it says “This program couldn’t be initializated”..
Do you know any other unpacker for DS roms?
I think you have to install microsoft .net runtime or something like that
i did it a while ago but don’t remember, however i used to have the same problem as you and i fixed it
try a google search with the exact error message you get
Unfortunately it didn’t work for me.
Tried it with 2708 – Shaun The Sheep (EU).nds
Still got the message that it can’t access the save file..
Someone any options?
Cheers,
Paddy
Umm Hiyo. I did everything that it said to do but… it didn’t work for my game “Prince of persia the fallen king.nds (E)” Why? It worked for my game Disgaea.nds and I did exactly.
Can you e-mail me the.nds file? if you cant just tell me how to do it
I tried doing this and it doesnt work on any game I have. The program must be bad or something. I own a Max Media Dock. Ive tried “patching” several different games and none work.
Mine didnt work too. Will there any error message if I dont have microsoft.net?
Thank you for that manual, it´s really great!!!
Did not work on Sonic(2699) But many thanks for trying to help
Make sure you have v1.18 kernel running on the R4DS. Does not work with all games but I patched Cake Mania 2. Thanks.
Arrrr didnt work for me got my hopes up aswell!!!
Did not work with wwe 2009.why?
I got a rom to work just to told that it has problems saving. Thanks for this tutorial though.
It worked great for me thanks, but i do have one problem. Since i patched it wifi won’t work, do you know of a way to fix this??
Tried it didnt work. Used arm7.bin from good game, Worked a treat Thanks.
worked for me a treat thanks very much its was a game that i really wanted to play aswell cheers again
Hi everyone. The method that has been posted is exactly right it’s just that the ARM7 file this guide says to download is outdated.. If you use the Arm7 file from ’100 classic book collection’ then that seems to currently work for all roms.
Hope i helped
Andy.
Brilliant Andy – that worked a treat!
thankyou soooo much ,, easy and simple thankyouu
I can’t work this..can someone please send me the link for the pre-patched Enchanted Folk And The School Of Wizadry rom please?
This would not work with club penguin
I overwrited the original arm7 file was this right?
I copied the arm7 file from a game that i knew already worked and applied it to rayman raving rabbids tv party, club penguin and gardening mama for my kids and it worked perfectly. thanks for your help.
Guys – u need to delete the current sav file to get it to work, and then it will work trust me…..
Cheers fr the dslazy link – been looking for this lol
Game trys to load using old sav file aas a ref point – so you get that error – delete the sav file – let it create a new one and it works
I think I’m missing something but I tried patching but the final .nds file I end up with is only approx 150kb in size o_O
Am I meant to patch this to the original rom? Or… What do I do with it? I’m kinda lost, I’m very new to this.
Thanks

Thank God, it finally worked. Thanks for the tutorial and gandalfthewizard’s comment… I put my n5ds card in my DS for the thousand time and i had actually no hope at all (‘couldn’t access save file’ was already planted in my brain) and suddenly i heard a tune and i saw all the adds coming, like Natsume productions etc…
Many thanks!!
I can’t open DSlazy.exe I have window with “aplication wasn’t inicjalized properly(0xc0000135). Click OK to close aplication.”
What to do?
(sorry for text’ bad quality, it’s not my mother tongue
Can someone tell me how to find the sav file so I can delete it. Also, where can I find a good arm7 file that works. Thanks a bunch.
[...] but to save me typing it out, here is a tutorial with images and links to what you need aswell. Inteoria Black Blog [...]
This doesnt work for guitar hero and for gi joe’, the games keep giving me the same error message: can’t find the save file. a little help would be nice’ ;D
First off thanx for this easy tut u’ve put together.
Tried 2 games so far that gave ‘can,t find create/save file’ and both are now working.each rom already had a arm7 in so u just overwrite with the arm 7 provided rebuild and they played 1st time. Cheers
Hi all
I am managed to download the zip files for the games I want. I have winrar running. I unzip them get them on the sd. But when I put them onto the m3adapter, it say no system file. I have tried the r4 kernal I think, it didnt work. and I tried the first suggestion of dslazy couldnt get it to open. But I gathered it is similar to winrar.
Any suggestion the kids are nipping at my heals wanting their games.
Sandra
The problem is that you have missed out the last step which is patching it with Max overload 1.2. You need to patch it after you have packer the file then it should work. I hope you will find this helpful ^_^
it works for me but when i start the game i hear it but i dont see it
cheers! club penguin was not working for my sister, and this fixed it! thank you very much!
doesn’t work with GTA chinatown wars..
thx for trying to help!
The download links are outdated and don’t work. Is there anywhere else i can download these files?
7-Zip is a better rom unpacker – That program is screwed
