We need to wait some time to understand how this backwards compatibility works.

If it's nothing more then ports without 1080p then Microsoft did the same pr bullshit they always do and i will never trust them again. In this case wewill only see a few x360 games ported on x1.

If howewer they managed to do an x360 emulator that only need some adjustment in settings for the port they totally nailed and we are going to see in small time most x360 games ported on xone. If this is the case i'm really impressed.

Wait, another thread on this? Why not share this in the existing threads? *sigh* This really seems to be something that bothers or even frightens people when so many threads get started for the same topic. Let me prepare an answer to OP in the next reply...

in order to make it work the executables need to be modified a little to properly hook in to the hardware, in order to modify a game they need permission/licensing from the content owner, no license, no modification.

Native would require physical xbox 360 hardware onboard.
The Xbox One however, is powerful enough to emulate the 360 when its primary executables been modified to redirect gpu, api and ui hooks to the xbox one system, so this "fact" is untrue.

As illustrated above, the process requires modification to core files to properly work, this isn't porting, this is reconfiguration, the base system is still being emulated to match the original hardware, so again, this "fact" is untrue.

Each game needs to have the content owners permission and licensing to allow Microsoft to modify and redistribute a modifled and packed version of the game, again it is not being ported, its being emulated, backwards compatibility does not require universal support, and theyre not lying by saying that theyre introducing backwards compatibility, you are still able to run the supported games that you already own, on the new system, at no additional cost.

Some games use platform tricks to achieve certain effects, in these cases they would not work even with modification because the hacks and tricks used are so edeeply woven in with the game that the emulator cannot possibly accomodate it.

However, the fact that some games cannot be played disproves your "fact" about the games being ports, if they were genuinely porting the games theres no technical reason why some titles could never be ported.

You have at best opinons here, please don't pass them off as facts.

Good question. http://news.xbox.com/2015/06/xbox-microsoft-unleashes-xbox-one-backward-compatibility-game-streaming-in-preview

They emulate the whole 360 system, not just the games. You can see the 360 dashboard in the video.

"Play against Your Friends on Xbox One and Xbox 360: Starting today, you can play against your Xbox 360 friends on Xbox Live, whether or not they are in the preview program. Just invite them to a party in the Xbox 360 menu and jump right in. Xbox One and Xbox 360 gamers can play the same game at the same time, against each other."

It works basically the same as PS1/PS2 classics already do on PS3 and Vita, from what I understand. Games have to be ported over on a game-by-game basis. But Microsoft's solution seems to have the added benefit of being able to use a disc for authorization, rather than having to re-buy your games digitally.

Wait, what? MS themselves, at the conference, explained the exact points you are raising so where is the bluff? They said that about 100 games will work this fall, and therefore backwards compatible. I have soon played through Super Meat Boy and will start playing Mass Effect and haven't seen one bug yet. However, these 15-20 games are part of MS beta testing, which they explained. Also, they clearly stated that all games will be published if the publishers give their permission. So what is your complain again?

cool that works for me, as long as the games I play gets supported I'm good.

Fact #1: The Xbox One is not "natively" backwards compatible with the Xbox 360.

If it was, you would be able to stick a disk in and play or download your current 360 game and play. You cant.

But what about games you bought digital? Then there is no disc (written with c, with k means a hard-disk) to insert. Would you call it backwards compatible in this case?

"Fact #2": The Xbox One will never be "natively" backwards compatible with the Xbox 360.

Why? The Xbox One and Xbox 360 have irreconcilable hardware differences and the Xbox One is simply not powerful enough to run the 360 games via emulation.

So how does MS achieve this? We already talked about it in another thread and I already explained that they are most likely using a professional emulation solution. Also MS already said that they use a virtual machine for this. Perhaps next time just try to investigate at first before just saying something because you think so.

Fact #3: Some Xbox 360 games are being ported over to the Xbox One and these ports are what Microsoft uses to claim backwards compatibility.

And another hint that you don't understand what is behind this and you are forking another "fact" based on a false starting point.

Fact #4: Some Xbox 360 games will never be included in this list.

Why? Each game needs to be ported individually and the host of bugs and performance optimizations needed to make the game work on Xbox One will overwhelm Microsoft engineers. Therefore, only select games will become "backwards compatible".

So you looked into your palantir and already know what will happen because of what? And again you say ported which is, again of course, false.

Fact #5: Microsoft did the same thing with the original Xbox when the Xbox 360 launched and gave up because it was too much work. Therefore only a select few original Xbox games ended up being backwards compatible.

Yep, happened once, will always be the same, can't be different. Like with everything in history...

You evidently don't know anything about the current solution but you have a strong opinion it will be the same like with 360 bc with Xbox. Sure.

Conclusion: The thread is more based on opinion and prejudices than on knowledge and objective facts.

Disappointed.

I still believe the game are simply (well painfully) ported (at least a some piece of it), not 100% emulated. For instance apparently Perfect dark now runs at 1080p on XB1, so it's definitely not 100% emulated, some parts of the code have being obviously modified.

The only thing to be determined is to know how much of the game is emulated, how much is painfully ported.

its the same as nintendos virtual console.
