You need to have a Hard Drive in your 360 however, but it IS backwards compatible.

Yeh, of course they will. It's how Nvidia makes its money.

MS are paying Nvidia for the GFX cards it puts in the new Xboxes.

Basically:
The reason the PS2 could play PS1 games is because the processors in both machines have the same architect (Or similiar), most likely the x86 architect.

The Xbox and Xbox 360 have different processors, which means they have a different way of reading the game code. The 360 will need to emulate the x86 architect to read the games, which will be done via the HDD - the PS2 didn't have this problem because it had the same processor type.

The Xbox and 360 problem is the same problem that goes on between Macs and PCs (Although I think that problem is soon going to become void?).

Oh.....



.....Right....



.... I read something on a website about giving nVidia an amount for every machine sold... So automatically thought it was for the grpahics chip.

My apologies.

The problem with Xbox games is that they are compiled in x86 assembly code and the 360 uses IBMs PowerPC assembly code..

It has nothing to do with the graphics chips as they are running on DirectX and are completely complimentary.

The new ATI is able to do everything the old card, which was DX8.1 compatible, can do.

That's why they need to have some way of recompiling the games, and has nothing to do with whether the new gra[hics chip can do what the old one can, because they CAN.

Yes, however the PS2 also housed some PSone hardware that was necessary to play the PSOne games... it definitely wasn't done just through software.

For every DirectX8 GeForce 3 that Microsoft would need to include in the 360 for seamless backward compatability, they'd A) Have to pay for the chip and B) have to pay a percentage of profit to nVidia. I believe the same is the case with the CPU, although that might not be necessary.

I think Microsoft are taking quite a few big risks. The non HD-DVD drive, lack of complete backwards compatability and, somewhat ironically, the low price of the machine could all cut the 360's life too short. When the PS3 comes out, it'll be the be-all and end-all of entertainment machines. If the 360 doesn't match the price, people will think it's not as good, if it isn't as powerful, people will stick with buying a PS3. I don't need a PS3. I won't use ANY of the features of the console other than the games-playing one... maybe to play the odd Blu-Ray film, but I don't buy DVDs anyhow. LIVE does it for me, but won't do it for all gamers... Microsoft need to market the hell out of the 360 and get it in homes before the PS3 is even out!

It could work, but to get it to work would be mucho expensive.

Why not just do what the PS2 does? If you want to play a PSOne game on it you only need one emulator, and that's the one that's built into every PS2. All you need is one piece of software that turns the XBox360 environment into an XBox environment in the same way.

Indeed.

Maybe a program, then, that detects an XBOX disc, recompiles the data as it's read and buffers it on to the HDD.

It's all too complicated... they really should have considered this when they first started... I agree with dumping nVidia (but i'm an ATi fanboy).

Hopefully the X900 range will own.
