File Extension ROM

File type: Read Only Memory Image File

About the ROM file type:

If Windows cannot find the appropriate program associated with .ROM files, then your registry may have errors. Check your Windows registry for errors (includes file association errors).

The .ROM file extension is associated with ROM emulation files or update files. These are generally images (or, in very simple terms, duplicates) of the information contained on read-only video game cartridges or on computer chips and read using bespoke ROM device readers specific to the device being read. These ROM images are then played on PCs using emulations software.

Additional Information:
To execute .ROM files you will need to identify the specific type of hardware that the ROM image is associated with, and then install the relevant emulator.
