You are still limited to running on the xbox 360's xbox 1 emulation, as you are modifying the title of avalaunch to halo so it can run, so I am pretty sure you cannot run classic xb1 games unless you modify all the titles, which even then, you will still run into problems. Maybe when we unlock emulator a bit more, it will allow us for a lot more support, but I don't see it happening any time soon. But this is great news, people seem to be making more and more progress with homebrew on the 360 every day which is great.
