A hacker group has released a “patch” that will allow DirectX 10 games to play on Windows XP under DirectX 9. This means that Halo 2 and Shadowrun for the PC can run on Windows XP, something that Microsoft told us was impossible.
While they aren’t in the best graphics ever, the games play, and that’s important for most people. However, things like Vista Live and achievements won’t work as those are for Vista only at this time.
The games have to be bought (these are unmodified games) from a company called Falling Leaf Systems (which apparently is the hacker group) and you will then receive a product they call “Alky Compatibility Libraries” which makes the games to be compatible.
