The other day I was playing Earthbound on Zsnes. For those who have played, there is a screen after you've saved which says 'power off or reset', which requires an action of either of those; a screen of which you cannot get off. Stupidly, I saved state there and then. When I logged back in, I was on that screen and I couldn't get off, never mind which button I pressed. I'm so far in the game, I do not want to start again.
So I was wondering, where does Zsnes save the save files? I was wondering that if I go into the designated folder on my windows pc I may be able to trace a save file before the impossible one to load and do that one. But I can't find where it goes. Is it in the actual Zsnes software, if so, how to I get onto it? Or is it accessible by my computer, if so, what are the steps to get into that on windows 7? Thank you for your help.
