.NSM File

The nsm file extension is mainly related to NESticke, an older Nintendo NES emulator for Windows/DOS.

The nsm file is some sort of movie file, recorded ending of a video game. Seems like very old fle type.

This nsm file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.

How to open:

Use compatible tools to work with *.nsm files.

How to convert:

Probably can be exported to other formats.
