So, those with an interest in preservation are actively seeking older arcade and video games and attempting to dump them to ROM images. 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. This is beginning to become a problem as early computer systems may be presently fifty or sixty years old while early home video consoles may be almost thirty years old. While black-and-white photographs may survive for a century or more, many digital media can become unreadable after only 10 years. The lifespan of digital media is rarely great.

Software which is being developed for embedded computers is often written to ROM files for testing on a standard computer before it is written to a ROM chip for use in the embedded systems. ROM images are used when developing for embedded computers. Video game console emulators typically take ROM images as input files. It is currently implemented by MAME and a variant of the CPS-2 emulator Nebula. This was resistant to emulation attempts until June 2007, when the encryption method was reverse-engineered by Andreas Naive. The game would send data to this hardware by attempting to write it to specific areas of ROM thus, if the ROM were writable, this process would corrupt data.Ĭapcom's latest arcade board is the CPS-3. Some games, such as Game Boy games, also had other hardware such as memory bank controllers connected to the cartridge bus. Alternatively, the game may simply attempt to overwrite critical program instructions, which if successful renders it unplayable.
By reading the value back to see whether the write succeeded, the game could tell whether it was running from an authentic cartridge.
Pirate cartridges also often used writable chips instead of ROM. On an authentic cartridge this would do nothing however, emulators would often allow the write to succeed.

The full decryption algorithm was cracked in 2007 by Nicola Salmoria, Andreas Naive and Charles MacDonald of the MAME development team.Īnother copy prevention technique used in cartridge-games was to have the game attempt to write to ROM. Their stated intent was to wait until CPS-2 games were no longer profitable to release the decryption method (three years after the last game release).

The original crack by the CPS2Shock Team was not a true emulation of the protection because it used XOR tables to bypass the original encryption and allow the game to play in an emulator. This contained a heavy copy protection algorithm which was not broken until 7 years after the system's release in 1993. However, as early as 2000, hackers found a way to decrypt and dump the ROMs successfully, making them playable once again in a Neo Geo emulator.Īnother company which used to employ methods of copy prevention on their arcade games was Capcom, which is known for its CPS-2 arcade board.
Many thought that this would mark the end of Neo Geo emulation. SNK also employed a method of copy prevention on their Neo Geo games, starting with The King of Fighters in 1999, which used an encryption algorithm on the graphics ROMs to prevent them from being played in an emulator. It was not until a security hole was found in Phantasy Star Online Episode I & II that GameCube games could be successfully copied, using the GameCube itself to read the discs. For instance, the Nintendo GameCube used non-standard 8 cm DVD-like optical media, which for a long time prevented games stored on those discs from being copied. Viewing this as potentially reducing sales of their products, many game companies have incorporated so-called features into newer games which are designed to prevent copying, while still allowing the original game to be played. While ROM images are often used as a means of preserving the history of computer games, they are also often used to facilitate the unauthorized copying and redistribution of modern games. For most common home video game systems, these devices are widely available, examples being the Doctor V64, or the Retrode.ĭumping ROMs from arcade machines, which are highly customized PCBs, often requires individual setups for each machine along with a large amount of expertise. ROMs can be copied from the read-only memory chips found in cartridge-based games and many arcade machines using a dedicated device in a process known as dumping.
