Problems with saving on Project 64

[blitz]

hi.

i downloaded project 64 and started to play zelda: the ocarina of time. after i've played a while, i saved my game on Slot 10. then i saved for about every 10 minutes i played(still on Slot 10), and just to be sure that everytime was being saved, i checked if it worked to load, and it worked perfectly. and after playing for about 3h, i saved my game a final time before i quit it. and the next time i started zelda and loaded my save on slot 10 i ended up way before where i saved the final time (in goron city, just played the tune for darunia), and now i ended up on a save i did like 1h before, and i'm 100% sure that i saved on slot 10 every time. cause i have tried to load every slot, and 10 is the only one working.

i've loaded the game from slot 10 many times before, and then it worked. except for one time when i ended up just before going into the deku tree, and actually i had already finished the deku tree, but i did't care so much then and just thought that i had forgot to save. but when it happened the second time i knew something was wrong.
and now it seems meaningless to play the game if the save only works now and then, but i really want to play it, so if anyone know anything about this, please help me!

thanks!

Don't know why it won't load but if you keep haveing save problems switch over to 1964 then all you'll need to do is load the save onto it.
Also when your saving on 1964 it's best to save on a slot 2 times in a row to make sure that it saves properly.
