Do you have Project64 1.6? If yes, do you have save data for OOT on 1.6? If yes, go into the folder "Save" in Project64 1.6's folder, and copy and paste "THE LEGEND OF ZELDA.sra", or whatever the save data file is called (most likely will be "THE LEGEND OF ZELDA.sra"), into the "Save" folder in Project64 1.7's folder. If the answer was no to any of the above questions, then I am unable to help you.
