List of Xbox games compatible with Xbox 360

From Wikipedia, the free encyclopedia

A list of Xbox games that are backward compatible on the Xbox 360 stands at the heart of this article. This list has experienced significant fluctuations over time and many of these are noted below. Additionally, the manner in which backwards compatibility is achieved and the software errors associated with it are discussed in brief.

[edit] Fluctuations in the list of compatible games over time

The original list was composed of 213 games and was unveiled on November 11, 2005 on the Xbox.com website; however, some games have been subsequently removed due to bugs. The following 13 games were removed from the list, although 4 of them have since been re-added: Catwoman (now re-added), Codename: Kids Next Door - Operation V.I.D.E.O.G.A.M.E., Curse: The Eye of Isis, NBA LIVE 2003, Sid Meier's Pirates! (now re-added), Star Wars: Clone Wars (but works in Europe), Blinx 2, FIFA World Cup 2002, Grabbed by the Ghoulies (now re-added), Legends of Wrestling, Mortal Kombat: Deception (now re-added), and Rugby 2005. He-Man: Defender of Grayskull remains on the list despite the fact the game was never released (it had been cancelled by the developer before completion). The Japanese version of the console was initially compatible with only 12 games, while the European version had 156 games.

Microsoft continues to expand on the number of Xbox games available for use on the Xbox 360, eventually hoping to make the vast majority of original Xbox titles backwards compatible. The last update for backwards compatibility in the US was December 14, 2006, raising the total number of Xbox games compatible with the Xbox 360 to 298. Approximately 30% of the original Xbox library is now compatible with the Xbox 360 (as of the August 28 update). The latest European update was December 2006, now with a total of 295 compatible games. The latest update for the Japanese was December 14, 2006, with only 71 working games. These updates can be downloaded from xbox.com and Xbox Live.

[edit] How compatibility is achieved

According to Microsoft, each game needs an emulation profile to run. These profiles can be downloaded through the Xbox Live service or at Xbox.com and burned on CD or DVD recordable media. The profiles are downloaded as a single bundle, and hence only need to be applied once per update (if doing so offline), or are automatically downloaded the first time a backwards-compatible game is inserted.

The Xbox 360 hard disk is required to play the games on this list. The hard disk is used not only to store the emulation software, but also to store saved games, store downloaded content, and to serve as a data cache for titles which utilize disk caching. Since games for the original Xbox were designed with the expectation that a hard drive would always be available, most titles rely heavily on the presence of one.

An early version of the emulator for playing Halo: Combat Evolved and Halo 2 offline was included with the Xbox 360 hard drive at launch. Xbox 360 hard drives manufactured later include updated emulation profiles which allow a greater range of titles to be played out of the box without updating. Whenever a new version set of emulation profiles is released, drives manufactured after that date automatically include the latest update.

[edit] List of compatible titles

In the following list, any Xbox game with a "Yes" for its region will work in that region, and only in others which also have "Yes" (although cross-region compatibility is not guaranteed). "Yes" in the 60Hz column indicates that the PAL title supports 60Hz output mode, and thus is compatible with the Xbox 360 VGA cable. Any game not on the list at all does not work in any region at present.

[edit] Backward compatibility errors

When an original Xbox game has been emulator patched in accordance to Microsoft instructions it may still refuse to play on the Xbox 360. The following error message displayed on the Xbox 360 dashboard signifies this failure:

"This original xbox game is not supported on your xbox 360 console. An update to support this game may be available. For more info, go to www.xbox.com/games. X: 2689.0 B: 1884.0"

This message is identical to the one displayed when trying to play an unsupported or unpatched game for the first time. At this time no reference to the significance of the X and B variables can be found on the Microsoft Xbox website. This may be related to international region compatibility; a Microsoft disclaimer notes:

"Currently the North American versions of these games are the only ones supported as backward compatible titles on Xbox 360."

PAL games that do not support PAL-60 cannot be played using the VGA HD Cable. Microsoft has an article on this here.

Additionally, a number of titles are technically backwards compatible, but still contain emulation errors or glitches. These are often minor, but can still include problems with graphics, sound, loading/saving, or gameplay. In some cases, Microsoft has subsequently updated the emulation profiles for individual titles, such that incidence of these issues is reduced or eliminated.
