Great emulator, using it on Xbox one. Here are some tips for abyone having problems saving. All games save the first time, some won't save a second time so on my phone I open my one drive account and I manually move my save which is located in the folder ".nesbox" to a new folder then save and it works. However it will only work for 1hr before you have to close explorer and reopen it for it to recconect wt one drive to be able to save for another hour. I save every 15m just in case. Also if you move a save back to the game folder make sure to delete whatever is after the game file. "save file.sfc(8)" for example delete the (8) or it won't read it.
