This is the emulator folder from my dsi system.
The way you speak seems that I want to not be able to open the file. I would love to get the save file in a standard format. Indeed I thought that saving in game would generate me a standard format. And for some reason I don't make a small idea it is not. I don't know how to export the save file from my emulator in a standard format. I just know to save in game and to use save state. That's why I'm asking for help, cause everything I know to do has already been done.
I need help to get a format that can be read by PKHex.
