XBOX 360 backwards compatibility...

[RollWave]

Anyone know?

Because it takes time. They have to write a software emulator for each game.

games were built for the intel celeron/p3 they had in the original xbox. the 360 uses a powerpc with 3 cores, so backwards compatibility is a bit difficult. thats why they have to rely on emulation, and that takes a lot of time, considering each game has to be carefully emulated.
