1. Download Patch.zip. (Credit to Rudolf)
2. Get and put Patch.exe and place your ROM(.nds) file to the same folder. You don't need to rename it.
3. Execute Patch.exe. That's all.
If you are concerned that you execute the patch.exe file on your PC, run it on the some virtual PC, or throw your hands up.
