I had been playing Final Fantasy 5 using Zsnes 3.3 in the living room, which is the only room in the house with satellite. My lady friend wanted to watch TV, so I transferred the 'save\ff5' folder to my bedroom xbox which happened to have zsnes 3.5. I loaded the save state and it totally didn't work at all. It was a frozen screen of what it was before. I put 3.3 on there and it worked.
So, is there any way to get a game save state, or the in-game save from tent/sleeping to work between versions?
