Maybe they are implementing the feature, but don't want to make too
broad promises, testing only the most popular titles?

More likely: They are supporting games which adheared 100% to the XBOX
SDK API. If developers decided to push it by making unsupported
hardware-specific calls, then those games are not supported.

I know this may be an overly technical answer for those who are not
programmers, but it is a valid one.

Just speculation, dude. Maybe my first impression was correct--just
the most important titles. Or maybe you're just talking out your ass,
as if you have access to the source code for all these games from
different companies. Whatever. Let me google and see if you were one
of the ones who said it couldn't be done..backtracking now?...

If that's true, it'll be interesting to find out why they can support
the feature on some games, but not others.

Can anyone find the story about MS having to pay royalties to the Xbox chip
maker just so they can have backwards compatibility with the new chip? I
don't know the makers or else I would. I know it is ATI and NVIDIA maybe?

But presumably all the shader-heavy titles are also the ones with
highest production value and therefore likely to be top sellers. Think
Halo 2, Splinter Cell 3, etc. And if I remember right, custom shaders on
XBox require very hardware-specific programming, so any emulation will
require some clever translation to ATI's chip.

Why the hostility, BTW?


I never said it couldn't be done, but I am fairly sure I've read
that XBox (1) shaders tend to be done in asm.

]I'm in the process of porting our Xbox shaders (all asm) to DirectX 9

And check this old article talking about the then-new GF4 (since
the XBox's graphics chip was a GF3 with some advanced features that did
not join the PC parts until GF4):
