ROM images (or ROMs, for short) is used in the context of emulation for a binary file which contains graphics, sounds, and program code. ROM images are usually created so that the software can be run on computer hardware different from the one the software was originally designed for, using emulator software.
The term's original meaning is "read only memory", a memory type that has often been used to store games and programs for game consoles such as the Nintendo Entertainment System or the Sega Genesis. Illicit distributors of vintage game images also frequently use it to refer to images of CD-ROM and DVD-ROM media, although many consider this technically wrong, preferring the term ISO images (ISOs for short).
The question of the legality of distributing and running ROM images is the prime issue between emulation enthusiasts and copyright holders, as many of those images are binary dumps of graphics, sound and program code protected by copyright. Some proponents violating these copyrights make the argument that since many of these games are no longer being sold the company is not being harmed in the process, often making a distant appeal to fair use. The concept of ignoring copyright for out-of-print computer programs is often referred to as abandonware.
The most rampant problem with ROM sharing is in Asia. In order to discourage this, Nintendo has used a new program format for the Nintendo DS.
