Microsoft ported four original Xbox games to the PC platform within the scope of backward compatibility efforts. With this breakthrough, the company also offered the native x86-based emulator used in Xbox 360 consoles to users along with the PC version.

When data miners examined the published game documents, they discovered that Microsoft was using the official Xbox 360 emulator codenamed Xe03. This emulator, also known as Fission, serves as the basic structure that provides backward compatibility with Xbox One and Xbox Series consoles.

Emulator structure within an emulator

The system developed by Microsoft actually contains another emulator within one emulator. While Xe03 runs Xbox 360 packages, it introduces a second layer called XeFu, or Fusion, to run brand new Xbox games.

Mod developers see it as a great opportunity that Microsoft has compiled this emulator for the x86 architecture. By modifying the application containers, independent developers were able to run Xbox 360 game files directly by disabling the Fusion layer.

XWine1 group, Plants etc. He announced that games such as Zombies, Steins: Gate, Fuzion Frenzy and Midnight Club: Los Angeles can be opened on PC with this method. Although the results obtained are now of varying stability, the use of official codes makes the optimization process much easier.

This development has great potential, especially for low-end handheld consoles. It is stated that the xe03 emulator can run on devices such as ROG Ally and Lenovo Legion Go with very light system requirements.

Advanced features and future prospects

Microsoft’s PC version can scale games from the brand new 480p resolution up to 4K. Additionally, the system; It also brings modern graphics features such as V-Sync, anisotropic filtering, advanced anti-aliasing and frameless window mode.

Since the games are included in the Xbox Anywhere program, users who have a digital license on the console can access these games on PC for free. It is also expected that Microsoft will bring Xbox Achievements support to backward compatible games in the future.

Although open source projects such as Xenia have been providing Xbox emulation for years, Microsoft’s own official solution is expected to offer higher efficiency. The company has not yet officially made a statement that Xbox 360 games will come to PC.

How do you think this official emulator step by Microsoft will change game archiving and playing habits on the PC platform?
