1. Download an unpatched DQ9 rom
2. Put it in a folder (and give it any name other than DQ9.nds)
3. Download both of the things from the links in the quoted post.
4. Download the fix (sorry, couldn't find link to the fix anymore... hope you have it or can find it yourself)
5. Put them in the same folder, and extract if necessary (may need Winrar for it, which you probably already have)
6. Start up "xdeltaUI"
7. Make sure you're on the "apply patch" tab
8. For "patch", select "dq9_patch1.patch.xdelta"
9. For "source file", select the DQ9 rom.
10. For "output file", name it DQ9.nds
11. Select the "patch" button. A 0 kb file is created, but after waiting 10-30 seconds, it will be around 230 MB and you should get the message that it was a success.
12. Use the fix.
After that, it should work. I hope it helps.
Okay, I get all that...but the problem I had is your very last step lol. Came to the same output. I got the clean rom, patched it with this translation (which does create a 0 file and then turns into a file about 229ish). However, when I go to apply the fix, instead of patching it then gives me a patched.nds file which is 0kb and stays 0.
So, maybe its the fix patch? Here is the fix I found and used:
