loss of save state in Majora's Mask

I am sorry if i am repeating myself but this save probme with majora's mask is taking my fun away form the game. I was just in the great bay temple and I had just picked up the 11th or 12th lost fairy. I use the save feature that pj64 has and I shut it off as well as the computer. I come back later and I opened the rom and go to restore my save. Instead I see nothing but the intro screen and I end up back at Clock town with my cheat codes but I lost the spot I was at. In other words I have to do it again but because this keeps happening, it worn't matter. No matter how far I get in the game and no matter how many times I save the same thing happens: back in clock town at day one:72 hours remain. It is really fustrating. Again I am sorry to repaet myself on this but this is making hard to enjoy the game when I keep losing my location. Please help!

I just lost the save that I had while I was in the woodfall temple and I had a native save state at woodfall with the statue. I use f5 to save and when I open the rom I use the drop down lists' restore opton f7. But again when I hit f7 nothing happened and when I used the games' save it wasn't there. What kind of cheats can be problematic? I use the infinite option, the have optoin with decu nuts and other weapons, the have bottle option and the option to levitate. What cheats can I use so that this doesn't happen again?
