<p>A ROM image, or ROM file, is a <a href="/facts/Computer_file/FjFH3Ufm">computer file</a> which contains a copy of the data from a <a href="/facts/Read-only_memory/P9QMuDLH">read-only memory</a> <a href="/facts/Computer_chip/fjn6vg7C">chip</a>, often from a <a href="/facts/ROM_cartridge/mWLcNez7">video game cartridge</a>, or used to contain a computer's <a href="/facts/Firmware/62UVKIUK">firmware</a>, or from an <a href="/facts/Arcade_game/oBYn85uk">arcade game</a>'s <a href="/facts/Arcade_system_board/dCRltFVF">main board</a>. The term is frequently used in the context of <a href="/facts/Video_game_console_emulator/lps69Dn3">emulation</a>, whereby older games or firmware are copied to ROM files on modern computers and can, using a piece of software known as an emulator, be run on a different device than which they were designed for. ROM burners are used to copy ROM images to <a href="/facts/Computer_hardware/8jSjsCNv">hardware</a>, such as <a href="/facts/ROM_cartridge/mWLcNez7">ROM cartridges</a>, or <a href="/facts/ROM_chip/P9QMuDLH">ROM chips</a>, for <a href="/facts/Debugging/QtdpPJT0">debugging</a> and <a href="/facts/Quality_assurance/BhDeyhel">QA testing</a>. </p>
