XenonRecomp is a software tool that converts Xbox 360 executables into C++ code, allowing for the potential porting of Xbox 360 games to PC. This process is unofficial and may face challenges from original publishers. While some games, like Sonic Unleashed, have already been ported, the complexity of the process may limit the number of successful transitions. Many Xbox 360 titles were delisted from the marketplace when the old Xbox Store was closed, and XenonRecomp may be a key method for preserving these games. Xbox head Phil Spencer has shown interest in exploring options for delisted Xbox 360 games.
