I highly doubt they're gonna be emulating the PowerPC based processor of the 360, that's probably not doable on the XB1. Same goes for PS3->PS4, Cell was also based on the power architecture, in addition to having 9 cores and generally being difficult to develop for. Either way, there's no way the XB1 could've purely emulated the 360's processor at launch (or in the future without new dedicated hardware).Lightknight said:The 360 was close enough to x86 architecture to make this possible. The ps3 was entirely proprietary and has been recognized as a mistake on Sony's part as an attempt to purposefully obfuscate how to maximize performance because Sony was actually afraid that developers would tap out the machine too quickly. So that makes this considerably more difficult to emulate than the 360 was. I'm not sure the ps4 would be anywhere close to capable of emulating the ps3 even with it being 50% more powerful than the XBO. That's due to the uniqueness of the ps3 rather than pure power emulation.Xsjadoblayde said:Oh goody! That just leaves you, sony. Suck it up buttercup, pull up socks, bite the bullet, pull finger out of arse, get act together and catch the fuck up. Stop hoarding all the money and make a good business decision for once. No one will laugh at you. Not since the N.Korea spectacle anyhow.
If it is powerful enough to do that? Then yeah, they can do the same thing. But at least Sony has an excuse and has resolved the problem by moving to x86. Microsoft has had this capability since launch.
I simply don't know how much of a power demand PS3 emulation is. I will add that this is not backwards compatibility. This is only backwards compatibility for 100 games.
Since these intial 100 titles are mostly Microsoft's own games they're probably just going to recompile the original code for x86, hence why the game has to be downloaded to play first.
