Getting Xbox 360 games working on the Xbox One was quite a challenge for Microsoft. Only the Xbox 360's GPU is emulated and able to run unchanged Xbox 360 code. The CPU side of Xbox One software is ran through an automatic converter that Microsoft spent a fortune to develop, that translates the PowerPC instructions in 360 software into equivalent X86 based instructions that the Xbox One and Series systems can natively execute.
The stock Xbox One never stood a chance at fully emulating the Xbox 360. So Microsoft took this unusual route to make it possible by partially recompiling Xbox 360 games into Xbox One code that is then downloaded to the system.
While that compromise sadly makes sense, I believe the system must be online afterwards in order to play any installed backwards compatible content (At least that's the case for me, where I can't play installed BC games offline even though my XB1 is set to my home console). Hard to excuse that silliness.
Microsoft is brilliant to think of all that and pull it off. Too bad they weren’t brilliant enough to make the system just be backwards compatible right out of the box. For some reason I think they could’ve done that too, but didn’t because it goes against their mission statement, {Get every Mofo online at all costs!}.
