For all the people that need help with the patching(Or didn't read the README).
1) Go to:
This link here(it provides a Patching program)
2) Download the zip files.
3) Extract them to your desktop or a folder(The files are xDelta, xDelta GUI, and the all-important Readme).
4)
If you put the extracted files in a folder:
Place your Platinum ROM in the same folder(Copy it, or whatever) and place the Patch that your going to use in the Folder(Trimmed or Un-Trimmed).
It should look like this:
FolderName--->[xDelta] [xDelta GUI] [Pokemon Platinum ROM] [Both Patches]
If you placed the extracted files in your Desktop:
Place your Platinum ROM and your Patches in the Desktop.
5) Now that your done with downloading, Open up XDelta GUI.
6) It will say:
[___________________] Select Patch
[___________________] Select ROM
Obviously where it says "Select Patch", You'll place the Patch that you would like(The ones you Downloaded here)and select the
Trimmed(No AR codes but saves space for Pokesav if your using an Emulator for your PC) or you can select the
Un-Trimmed(AR codes are available).
Aaaaand where it says: "Select ROM", You'll put The World Ends with You.....NO you'll put your Platinum ROM
7) Click Apply Patch
8) Make sure your "Patched" ROM has the corresponding Megabytes(Check if it has 62+ MB)
9) When your ROM is Patched, just drag your ROM into your Flash card's Game folder and your good to go
