The file extension ROM can be associated as a Read Only Memory image or it can be related to the N64 Emulator used for the Nintendo 64 game cartridge. Read Only Memory files provide an exact copy of data related to a hardware device to allow updates to be performed on the firmware associated with the hardware device. ROM files used for the N64 emulator are also a read only file type that is used with the emulator to open and play Nintendo games without the use of the console.
ROM files which are considered to be Read Only Memory are a miscellaneous file type that can contain a variety of different content, especially if it is used as a backup tool for hardware devices and firmware updates. Backup ROM files contain an exact copy of the original data to be used at a later date for purposes of restoration. The files can contain data for a specific application, firmware, or an entire partition on your PCâ€™s hard drive.
If the ROM file is related to the N64 Emulator, it is a game file type that contains a copy of the contents for a specific Nintendo game in the form of a ROM image to allow you to use the game with an emulator program. The ROM image replicates the data which is stored on Nintendo video game units.
