Due to this aging, there is a significant worry that many early computer and video games may not survive without being transferred to new media. So, those with an interest in preservation are actively seeking older arcade and video games and attempting to dump them to ROM images. When stored on standardized media such as CD-ROMs and DVD-ROMs, they can be copied to future media with significantly reduced effort.23

While over time many original copies of older games may deteriorate, be broken or thrown away, a copy in ROM or Image form may be distributed throughout the world, allowing games which would otherwise have been lost a greater chance of survival
