Original Xbox games start running in Xenia Edge, through the Xbox 360's own compatibility emulator

Xenia Edge, has207's fork of the Xbox 360 emulator Xenia, can now start original Xbox games. It does not emulate the first Xbox itself. Instead it runs XeFu, which the app's own text describes as "the Xbox 360's backward compatibility emulator", and lets XeFu run the older game the way a 360 would.

What changed

Build c434702, published on 6 October, lists four changes: "Run original Xbox games through XeFu", "Scan for original Xbox games", reading original Xbox executables, and listing those games under their own names. A game XeFu runs is recorded with its own title ID, name and title image, and XeFu itself never shows up in the game list. The commit behind the first says that opening an .xbe, an original Xbox disc image or an Xbox Original package starts the XeFu launcher with the game as the disc in the drive, and that a missing launcher or XeFu build is named in an error.

Two more builds on 7 October fixed where the emulator's kernel places three processor registers that XeFu reads, loaded XeFu's title data and reported it when missing, and stopped controllers appearing to unplug while Xenia's own menus are open. Shader storage is now kept per original Xbox game. One commit notes that xbox.xex and the XeFu builds share the title ID FFFE07D2, so Edge tells them apart by their original file names.

Bring your own console

Xenia Edge ships none of XeFu. The emulator's error message says the files come from an Xbox 360's hard drive, so players need them from their own console. The project's README calls Edge "yet another experimental fork" of Xenia, and the feature is new: the r/emulation post that spread the news on 6 October was headed "Xenia Edge Adds Experimental Xefu Support".

That post linked a video by Ahayri, not the developer, showing FIFA Soccer 2003 running in build c434702, with XeFu's title ID, FFFE07D2, in the window title. Neither the release notes nor the README list which original Xbox games work.
