itch.io

Found it works for an hour before I have to reload the browser. Also some games don't let me save twice unless I move the first save state to a new folder. See my comment above for more info.

My legal copy that I backed up doesn't have that issue. Perhaps buy a differnt version and back it up and try again. Could be a pal version and you need Ntsc?

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.
