You should have wrote the tutorial, which i did. But anyway, congratulations!
It´s already explained how to play neo mario galaxy in its section lol and I don´t think that moving 2 files into your SD card needs a tutorial
Super Mario Galaxy Hacking
I Already know how to:
-level edit with whitehole
-test my levels on dolphin
-adding paths in whitehole
-make custom textures (finally!)
-edit text (thanks to JasonTGF)
-make custom models
I need to know how to:
