testing for the xbox 360 ie browser

Obscure, but we've just had a dev request come through to specifically support the: Internet Explorer, Xbox 360 (not One) browser.

I've checked with BowserStack and Parallel amongst other usual sources as well as the xbox 360 developer docs and can't find any mentioned of an available emulator for this platform (and damnit, but the boss won't let us go buy an xbox ;) )

Has anyone come across on of their dev travels?

FYI we're testing a JS, Angular 1, SPA ideally from OSX but could utilise Windows if a solution was available on that platform - paid for options are completely acceptable.
