Microsoft backward compatibility first debuted two years ago, allowing a select range of Xbox 360 titles to run on Xbox One consoles. With support for existing both physical Xbox 360 discs and digital downloads, the program was a free solution to play your favorite classics of the last generation.

Today, at the Xbox E3 2017 press conference, Microsoft has announced the backward compatibility program will be expanding to support original Xbox titles. While it's still unclear which titles will support the program for its launch later this year, Microsoft's own "Crimson Skies: High Road to Revenge" will be among the initial library.

Although we can expect original Xbox game discs to be supported, it's currently unclear whether classic games will be making it to the Xbox Store.

Update: Xbox marketing lead Albert Penello has offered some clarity on how this whole thing will work, including good news on the disc front.
