The NMM format belongs to Nightmare, a Microsoft Windows program for hacking and editing Game Boy Advance ROM images.
An .nmm file stores a module used by Nightmare. The module supplies information that allows the program to work with particular data in a ROM image.
The Nightmare module format is obsolete and is no longer in common use.
Open an .nmm file through Nightmare on Microsoft Windows. The file is intended to be used by the program as a module rather than opened as a standalone document.
Because Nightmare is obsolete, the file may not open correctly on current systems unless the original program can still be run.
An .nmm file is a Nightmare module, not a general-purpose media or document file, so it has no useful standard conversion format.
To preserve its contents, keep the original file with the Nightmare project or ROM-hacking files that use it. A compatible version of Nightmare would be needed to inspect or recreate the module.
