Umm, xbox one's backward compatibility is done through an emulator, meaning the ISA difference is already covered.the CPU isn't the same architecture. The XBox One uses x86 and the 360 was RISC. The instruction set for executing programs is different.
What? How is it answered? All emulators in existence are able to use the original data from the discs and do not need to download anything. X1 uses an emulator and yet is unable to install the game from the disc and has to download it in full. Why? If it's an emulator, then why can't it read the disc data?So if you know the answer why ask a question?
They have to actually change the code to be compatible. Microsoft does this at the request of the developer or publisher for free.

Why are you mocking me? It's a genuine question since this emulator is unique among emulators. I'm not saying it's doing a bad job; just interested to know why it doesn't do direct emulation.OP can feel free to contact Microsoft if they think they have a better way to improve their backwards compatibility.
