What is a ROM file?

ROM files have multiple uses, and Read-Only Memory Dump is one of them.

Read-Only Memory Dump

ROM stands for Read-Only Memory Image. Files with the .rom file extension are used by computer hardware to update the data that is stored on the computer systems. Common uses for ROM files include the updates of computer BIOS and computer video cards.

ROM files are also used by many gaming device emulators so that computer users can play their favorite video games on their computers rather than on the actual video game system console. These files contain an exact copy of the game from the original gaming cartridge, allowing users to play the game without having access to the actual game system or game cartridge itself.
