testerom

testerom is a term that refers to a digital file containing the raw data from a Read-Only Memory (ROM) chip, typically found in video game cartridges, arcade machines, or other electronic devices. These files are essentially digital copies of the original software embedded within the hardware. The process of creating a testerom is often referred to as "dumping" the ROM.

testeroms are commonly used for various purposes. Preservationists create testeroms to archive historical video games and software, ensuring they can be accessed and played in the future even if the original hardware fails. Developers and hobbyists might use testeroms for reverse-engineering purposes, studying how the software functions or for creating modifications and fan-made games.

The legality of possessing and distributing testeroms can be complex. While creating a testerom of software you legally own for personal backup or archival purposes is often considered fair use in many jurisdictions, downloading testeroms of copyrighted material without owning the original game or hardware can constitute copyright infringement. The distribution of such testeroms is almost universally illegal. Emulators, software that simulates the original hardware, are often used to play testeroms.
