How to Change, Edit, or Hack Textures in Super Mario 64 (Very Easy to do)

You will need Toads Tool 64 for this and, as always, an extended SM64 Rom. First, Open your Rom and after it's done opening, go to "Edit Textures" on the Top of the Program. Here you can view all the Textures are used in the game.

To Change a Texture, click on one, then click "Import from PNG" on the right side of the program. Now find an image you want to replace with the Texture with, and open it. You can also Export Textures into PNG image files by clicking "Export from PNG" and edit SM64 textures either using Microsoft Paint, Paint Brush for Mac, or GIMP And Replace original textures into your edited ones. You can also Revert Textures by Clicking "Revert Texture from ROM" on right.

Have Fun Changing Textures!

Hmmm....Thats a bit too easy.
Try a harder technique.
