Xbox One users may now be able to play games that are compatible with older consoles through Xbox Backward Compatibility (BC) feature.

Four more games were added to the roster of BC games, such as the highly popular "Cars 2: The Video Game," the "Dead Rising 2: Case West," the "Dead Rising 2: Case Zero" and the "Meet the Robinsons."

However, fans are still expecting for the "Call of Duty 2" to be included in the BC program. Many fans and users are clamoring for the game since the introduction of the feature.

Earlier, the highly popular game "Street Fighter 4" was included into the program. The nostalgic game was accompanied by three more other games such as the "Luxor 2," "Poker Smash," and "Madballs Babo: Invasion."

There are games, however, that may need subscription before access to users. Fans who subscribed to Xbox Live Games with Gold program may also avail of free Backward Compatibility games such as "Borderlands 2" and "Heavy Weapon" this March.

The full list of games includes these popular titles such as "Star Wars: The Force Unleashed," "Rayman 3 HD," "NBA Jam: On Fire Edition," and many others.

Microsoft announced its intent to add the compatibility program to its consoles during the Electronic Entertainment Expo 2015. In November 2015, 104 games were initially unveiled as the part of the program.

Explaining the engineering behind the Xbox One Backward Compatibility program, Phil Spencer, the head of Xbox division, explains: "The 360 games think they're running on the 360 OS, which they are. And the 360 OS thinks it's running on the hardware, which it's not, it's running on an emulated VM."

"On the other side, the Xbox One thinks it's a game. That's why things like streaming, game DVR, and screenshots all work, because it thinks there's just one big game called 360," he further explained.

However, multi-disc gaming will not feature in this program as there are no existing systems for this particular game type yet.
