Why xbox one backwards compatibility downloads the game instead of copying disc data to HDD?

[eddman]

Emulators like epsxe and pcsx2 use the original disc data. How come X1's emulator can't do the same? IINM it's the only emulator out there that is unable to use the original game data from the disc.

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.

Umm, xbox one's backward compatibility is done through an emulator, meaning the ISA difference is already covered.

The mystery to me is why it cannot install from the disc. All emulators out there can use the original game data. X1 is the only emulator that does not install from disc.

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.

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?

Probably to get the latest version of the game?

I thought I remember reading way back when that each 360 game that becomes BC on X1 is done so by specifically making that game BC on an individual basis. There is no 1 solution for all games which is why not all games work for BC. So that would make sense that you'd have to download something in order to make the specific game you want to play work on the X1.

OP can feel free to contact Microsoft if they think they have a better way to improve their backwards compatibility.

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.
