[TUTO] Xbox One / Series : le mode Développeur pour lancer RetroArch et des homebrews

On Xbox One and Xbox Series, there is no exploitable hack on an up-to-date console. However, Microsoft offers an official and legal Developer Mode that lets you install applications (UWP) such as RetroArch and other emulators.


Steps
  1. On the console, install the Xbox Dev Mode app from the Microsoft Store and note the code shown.
  2. On a PC, create a Microsoft developer account (Partner Center). Individual registration has a one-time fee and requires identity verification: check the current terms on Microsoft's site.
  3. Enter the code on the Partner Center's console activation page, then Agree and activate.
  4. In the app, choose Switch and restart: the console reboots into Developer Mode (Dev Home).
  5. Enable the Device Portal in Dev Home, open its address in your PC's browser and install the application (.appx or .msix file) for RetroArch or the emulator you want, along with its dependencies.
  6. To play your retail Xbox games, reboot into normal (Retail) mode from Dev Home.

Good to know
  • In Developer Mode, retail games and apps won't launch, and emulators don't work in normal mode: you switch between the two.
  • The Collateral Damage exploit (2024) only works on three old system versions, since patched. It does not let you run copied games.
