Backwards compatibility requires downloading the entire game? + how does it work?

So....apparently Xbox One 360 compatibility has you downloading the entire game over the Internet, rather than having it install from disc? I stuck in Fallout 3, and that's what seemed to be happening, a "6.2GB Update". (Although I had most of the One
games I've played download gigantic patches, so....?)

Also, anyone know how it works from a technical perspective? Since you're actually downloading the entire game, does that mean it's NOT emulation, that maybe they're recompiling games or something for the One + a 360 services API emulation layer, so like
the game you're downloading actually has x86 code?

I'm disappointed it's not just installing from disc, and disappointed they haven't included Xbox 1 games yet, but even the way they seem to be doing it is VASTLY superior to not having it at all. If I standardize on One, it'll be 99% because of the backwards
compatibility.

Can Xbox One console ban play backwards compatibility with Xbox 360 discs ?

Backward compatibility requires you download the entire 360 game from Xbox Live like an "update", even if you're simply using a disc.

As a banned console cannot access Xbox Live, it will ultimately not be able to play 360 games.

 

Downloading BO1 to XB1

Try downloading it from the Xbox store on your. Xbox under backwards compatibility.

 

You pretty much summed it up.

 

^^ Probably means original xbox

 

According to an article I read on the EuroGamer website, the team are recompiling the games to the Xbox One's X86 (or more correctly X64) based architecture. There is a certain amount of emulation going on, but not full emulation. This is why they are
downloaded when you insert a compatible Xbox 360 disc and not installed from that disc.

 

I get what your saying now. Xbox original games on back pat would be cool but I dont see it happening.

 

I found this article... if memory serves, it may have been on IGN's site... awhile back. Part of Phil Spencer's explanation of BC. If I'm not mistaken this is what he said at the E3 briefing, but I'm not certain.

"[Emulation] is hard," admitted Spencer, explaining that the company was dealing with having to harmonise PowerPC architecture with x86.

"The approach that we've taken is to actually emulate the full Xbox 360 hardware layer. So the [operating system] for the 360 is actually running when you run the game," Spencer explained.

"If you watch the game's boot you'll see the Xbox 360 boot animation come up. From a performance standpoint it allows [emulation] to work. We're able to get frame by frame performance equivalents."

"[Xbox Live] thinks you're on a 360, so people have been asking 'hey, why are you playing Mass Effect on the 360?,' I was actually playing on the Xbox One."

Spencer continued to explain that, since the Xbox One thinks it's playing a normal game, features such as streaming and screenshots are supported.

"The 360 games think they're running on the 360 OS, which they are. And the 360 OS thinks its running on the hardware, which it's not, it's running on an emulated VM. On the other side, the Xbox One thinks it's a game. That's why things like streaming,
game DVR, and screenshots all work, because it thinks there's just one big game called 360."

Delving deeper, Spencer explained exactly how the emulator packages the Xbox 360 games, and how it compares to Xbox 360's emulation of original Xbox games.

"You download a kind of manifest of wrapper for the 360 game, so we can say 'hey, this is actually Banjo, or this is Mass Effect. The emulator runs exactly the same for all the games.

"I was around when we did the original Xbox [backwards compatibility] for Xbox 360 where we had a
shim for every game and it just didn't scale very well. This is actually the same emulator running for all of the games.
Different games do different things, as we're rolling them out we'll say 'oh maybe we have to tweak the emulator.' But in the end, the emulator is emulating the 360, so it's for everybody."

Asked about whether Microsoft would require permission from game publishers to adjust game code, Spencer clarified it would not be interfering with code.

"The bits are not touched," he said. "There's some caveats, and as always I like to be as transparent as I can be on this: Kinect games won't work from the 360, because translating between the Kinect sensors is almost impossible."

Finally, the subject of multi-disc games was also addressed. According to Spencer, it's an issue engineers are looking into.

"We're still working on multi-disc," he said. "Lost Odyssey and
Blue Dragon are some of my favourites from the 360. There's actually work in packing a multi-disc into single that requires
us to go back and look at the original package on the multiple discs and reconfigure that."

 

this would explain why some GoTY versions r not working properly and DLCs r bugged preventing you from playing the game im happy now. iv never once bought a GoTY version cause reasons i get launch day versions and buy the Season pass/DLC like a real gamer


ppl paying a 3rd of wat iv spent full game on GoTY version to "save" money will find B/C wont recoqnize the "installed to disc" DLCs when for Xbone B/C it seems u need to download from xbox store for it to be compatible >_>
