Here is the super rare The Legend of Zelda: Ocarina of Time debug ROM!
Since this is a very specialized ROM, it won't work with just any emulator. And it doesn't work right out of the box (Or zip file). I included instructions that I found that tell you how to get it working in Project64 1.6.
Project64 1.7 works right out of the box, but it's a private beta. There's a leaked version that I won't link to. One Google search should give you plenty of download links.
Make backups of the ROM. Nintendo is really active in suppressing this particular ROM (Hence how rare it is) and these links may die after a period of time.
