Dynamic recompilation techniques used in Apple's Rosetta are able to run PPC code with 50% efficiency under an Intel core, so a recent quad should be a good replacement for the in-order, 90nm, 3-core Xenon. The Xenos GPU is related to Radeon R520 (X1600-X1900), so a high end video card should be able to keep up — the emulator could hook the API calls to the customized DirectX used in Xbox360, and translate them into native calls. Sure, there's the not-so-small problem of the missing specifications, and DRM keys for game decryption (stored in Xenon's ROM), but projects like Free60 have already uncovered vital information in their successful attempt to boot Linux. While obviously not a simple task, from where I stand such a project looks very interesting to take on. Could Slashdot tell us why we are not seeing any progress, not even a single open-source project attempting Xbox360 PC emulation ? What are the technical show-stoppers you anticipate ?
