Video game ROMs
List of the most common filename extensions used when the ROM image is copied from the original ROM device to an external memory such as hard disk for back up purposes or for making the game playable with an emulator. If the platform specific extension is not used then usually filename extensions ".rom" or ".bin" are used to clarify that the file contains a copy of a content of a ROM. When the data is in the original ROM such as game cartridge it is not a single file and does not have a file entension and is de facto an image of a filesystem.
