NS1 File Complications


Issues Opening NS1 Files

Nestopia Disappeared

When you double-click your NS1 file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Generally, this is experienced in %%os%% because Nestopia isn't installed on your PC. The typical path of opening your NS1 with a double-click won't work because %%os%% cannot make the program connection.


Tip: If you don't have Nestopia installed, and you know of another program to open your NS1 file, you can try opening it by selecting from the programs listed under "Show Apps".


Nestopia Requires Update

Your Nestopia Save State file is incompatible with Nestopia because you might have the wrong version installed. Download the latest Nestopia version from the Open Source website to ensure you have the correct one installed. This problem is predominately due to having a Nestopia Save State file version that was created by a newer version of Nestopia than what you have installed on your PC.


Tip: If you right-click on your NS1 file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.


Ultimately, most of the difficulties opening NS1 files are due to having the wrong version of Nestopia installed.


Associated Difficulties Loading NS1 Files

You can still experience errors opening NS1 files even with the latest version of Nestopia installed on your PC. If you are continuing to have errors with loading NS1 files, other external issues might be to blame. Additional factors include:

  • Corrupt Windows Registry file path references for NS1
  • The NS1 file description within the Windows Registry was removed
  • Defective install of a NS1 program, such as Nestopia
  • Your NS1 can't be loaded properly (file corruption)
  • NS1 file integrity has been compromised by malware
  • Device drivers for NS1-related hardware are out-of-date
  • Windows cannot load your Nestopia Save State file due to insufficient resources (eg. RAM)
