Microsoft is now suspending users who use Retail Mode emulators on their Xbox consoles
After a short-lived return, it appears as though Microsoft has put an end to running emulators on Xbox Series X|S consoles via retail mode for good. The developers behind UWeaPons, the workaround to loading emulators on Xbox's Retail Mode, had their consoles permanently banned by Microsoft. Additionally, users caught using UWeaPons on their system are receiving 15-day suspensions. It's now recommended that if you installed any retail mode emulators, you remove them from your console.
