Gaming Consoles & PCs Why Won't Original Xbox Games Work on 360? Common compatibility issues between Xbox consoles by Eric Qualls Writer Former Lifewire writer Eric Qualls has been covering the Xbox line of consoles and Xbox games since August 2004. our editorial process Twitter LinkedIn Eric Qualls Updated on February 26, 2020 Erin Huffstetler Consoles & PCs Xbox Buyer's Guide Tweet Share Email Thanks to the Xbox 360's backward compatibility, it's possible to play all of the best games for original Xbox on the newer system. If your Xbox games won't work on your Xbox 360, the hard drive could be missing key files that allow for backward compatibility. Information in this article applies to all Xbox 360 systems including the original and Xbox Slim models. It's also possible to play Xbox 360 games on the Xbox One. The Xbox One can run original Xbox games as well. Xbox 360 Backward Compatibility Issues The Xbox 360 hard drive uses a special partition to run Xbox games. Compatibility issues with the Xbox 360 usually occur when you replace the Xbox 360 hard drive. If you bought your console used or refurbished, the hard drive could have been swapped out before you purchased it. This is a common problem reported by players who buy from eBay. To make more money, some eBay sellers buy consoles with official 20GB Microsoft hard drives for cheap and replace them with larger laptop hard drives. That way, they can then sell them for less than an official drive of the same size would be and still make a profit. While these hacked hard drives will function exactly the same as an official drive, most of them are missing the partition necessary to run Xbox games. If you want to upgrade your console's hard drive, you should buy official Xbox accessories from established retailers. The Xbox 360 Slim and Other Models Original Xbox games work on the Xbox 360 Slim and other models with one exception: The 4GB version of the 360 Slim is not backward compatible. The 4GB Slim doesn't actually have a hard disk drive, so you'll have to install one with the appropriate partition to play original Xbox titles. Xbox 360 and Xbox Compatibility List While nearly every original Xbox title is compatible with the 360, there are a few exceptions. Microsoft has released a full list of Xbox games that work on Xbox 360. If you don't see the game you want to play listed, then you're out of luck. Although the Xbox 360 is backward compatible, it can't connect to Xbox Live while playing Xbox games. This is because Xbox Live support has been discontinued for the original Xbox. The original Xbox and Xbox 360 consoles are region-locked, so systems manufactured in the U.S. cannot play some games released in other countries.
