Notes about the NSG file extension:



Errors in your registry are one of the common causes for incorrect file associations on your windows system. It is highly recommended that you check your registry for file association errors (will also check for any other registry errors).

The NSG file type is primarily associated with 'Nessie'. Nessie is an NES emulator for Windows. You can use it to play NES/Famicom games on your PC. The NSG file format changed during the Nessie development so some older NSG files may not open in newer versions of the emulator. The game files should work; just the saved state file format changed.
