Looks like this is an issue for retail mode only, if you’re using developer mode to run emulators you shouldn’t have issues:
“Players could pay a one-time fee to get a developer mode attached to their console. From there, you could gain access to emulators. In fact, it looks like that option is still readily available. You will lose out on features made only for retail mode, which could mean going back and forth between the modes.”
I mean, if you want to do emulation there’s better/cheaper ways to do it than an Xbox, but at least the option is there in some form.
