I’ll say it again, don’t perform any of the steps, when you don’t have the original game by Nintendo
(ORIGINAL means = having the cartridge “in the hand”)
You have been warned!!

Everything you need for patching is in the pack! (besides the main rom)
Be sure you have installed the Microsoft .NETFramework-pack!
The tool won’t work without these “codecs”!

PATCHING

—————————————————————————————————–

Step 01:
Get your ROM [Please don't ask me where to get one]

—————————————————————————————————–

Step 02:
The ROM must be the [U]-Version of the game, the others won’t work!
[MULTI is included! MULTI --> ENGLISH, FRENCH, GERMAN, ITALIAN, SPANISH)

-----------------------------------------------------------------------------------------------------

Step 03:
Download the file from me and extract it!

-----------------------------------------------------------------------------------------------------

Step 04:
You'll have some separate files now! Ignore the other folders firstly!

• [U] New Super Mario Bros. 3 [Version 2.0x].xdelta
• READ ME! (important).txt
• xdelta.exe
• xdeltaUI.exe

—————————————————————————————————–

Step 05:
Open “xdeltaUI.exe”

—————————————————————————————————–

Step 06:
Remember, we want to patch our rom, so we have to click on the tab “Apply Patch”
[it should be marked in the default setting]

—————————————————————————————————–

Step 07:
You’ll see 3 empty boxes with 3 buttons to the right from each of them…

• 1. BOX – Patch
• 2. BOX – Source File
• 3. BOX – Output File

—————————————————————————————————–

Step 08:
Click on the first button “Open” right of the “Patch”-box!!
A new window should be opened!

—————————————————————————————————–

Step 09:
Search for my xdelta-patch now and double click on it
[the 1. box will be filled with the path!]

—————————————————————————————————–

Step 10:
Now to the second button, click “Open” right of the “Source File”-box!
Search for the “clean, not trimmed” (downlaoded) ROM!
Remember: Only the [U]-version will work!
—————————————————————————————————–

Step 11:
And at last, the third button! Click on “…” right of the “Target File”-box!
Choose a place on your harddisk to save the patched rom!!

—————————————————————————————————–

Step 12:
After saving the new file, you’ll realize it has no extension…
Right mouse click on the file and press “rename”!!

—————————————————————————————————–

Step 13:
You have to add “.nds” behind the name!
[Example: after saving "NSMB", after renaming "NSMB.nds"]

—————————————————————————————————–

Step 14:
Your game now is successfully patched!

—————————————————————————————————–

Step 15:
Get it on your flashcard or use an emulator to play the game! Have Fun!!

—————————————————————————————————–

Last Words:
I prefer a real DS, because it makes much more fun and you can see the true graphic power of New Super Mario Bros. 3!
DO NOT use NO$GBA!! Almost every level gets corrupt because of the graphic elements which cannot be rendered by this emulator! 

When you don’t have a DS, get one! Help NINTENDO!!
