Basics (Windows)
From CW-Games Wiki
In this tutorial, we'll stay inside the Terminal section, for easier and more accurate hacking. Start your Terminal, and begin!
First you'll need to go to the directory where you've placed. If you aren't sure how everything is called, try to list them.
C:\Users\Admin>CD Desktop
C:\Users\Admin\Desktop>DIR
Volume in drive C has no label.
Volume Serial Number is ****-**** Directory of C:\Users\Admin\Desktop
... (To long to list it here)
C:\Users\Admin\Desktop>
Now let's make a new directory, and move the green files to the newly created directory, go to it, and list it.
C:\Users\Admin\Desktop>MD hack C:\Users\Admin\Desktop>MOVE MKDS.nds hack
1 file(s) moved.
C:\Users\Admin\Desktop>MOVE ndstool.exe hack
1 file(s) moved.
C:\Users\Admin\Desktop>CD hack C:\Users\Admin\Desktop\hack>DIR
...
C:\Users\Admin\Desktop\hack>
And now lets start doing the real deal.
C:\Users\Admin\Desktop\hack> ndstool -x MKDS.nds -9 arm9.bin -7 arm7.bin -y9 y9.bin -y7 y7.bin -d data -y overlay -t banner.bin -h header.bin

C:\Users\Admin\Desktop>DIR
...
C:\Users\Admin\Desktop\hack>
And now, go to the Course directory, list it, remove the normal track, and give another track the name of the deleted one.
C:\Users\Admin\Desktop\hack>CD data/data/Course
C:\Users\Admin\Desktop\hack\data\data\Course>DIR
...
C:\Users\Admin\Desktop\hack\data\data\Course>DELETE cross_course.carc
1 file(s) deleted.
C:\Users\Admin\Desktop\hack\data\data\Course>REN old_mario_gc.carc cross_course.carc
1 file(s) renamed.
C:\Users\Admin\Desktop>
Now go 3 directories backwards.
C:\Users\Admin\Desktop\hack\data\data\Course>CD ..
C:\Users\Admin\Desktop\hack\data\data>CD ..
C:\Users\Admin\Desktop\hack\data>CD ..
C:\Users\Admin\Desktop\hack>
To end it, do this:
C:\Users\Admin\Desktop\hack>ndstool -c MKDSK.nds -9 arm9.bin -7 arm7.bin -y9 y9.bin -y7 y7.bin -d data -y overlay -t banner.bin -h header.bin

Now, that's it. But keep in mind, that it's untextured. How to make them textured, comes soon.
