 5. Run with `$ ./nestur path/to/rom_filename.nes` or `> nestur.exe path\to\rom_filename.nes`.
 6. If the game uses battery-backed RAM (if it can save data when turned off), a save file like `rom_filename.sav` will be created in the same folder as the ROM when the program is exited. When Nestur is run again, it will look for a file matching the ROM name, with a `.sav` extension instead of `.nes`.
