I did on a real n64. How I did it is simple: The crooked cartridge trick (pull up on left side slowly, hold down right side (Warning: This may damage your Cart!)). One done, if you see a yellow bar above the health, stop moving the cartridge and enter this to get to the debug menu:
1. Press and hold L, then R, then Z, then release all buttons.
2. Press and hold Up on D-pad, then C-Down, then release all buttons.
3. Press and hold C-Up, then Down on D-pad, then release all buttons.
4. Press and hold Left on D-pad, then C-left, then release all buttons.
5. Press and Hold C-Right, then Right on D-pad, then release all buttons.
6. Press and hold A, then B, then Start, then Release all buttons.
If done correctly, a message box in the top left of the screen will appear. You can cycle through the menus with A.

If you don't want to do the crooked cart trick, and you have 1.0, go to the fishing pond and cast your line at the door. This should work too.
