Alky's DirectX 10 Compatibility Libraries

Alky's DirectX 10 Compatibility Libraries is a collection of programming libraries aimed at developing DirectX 10-based applications and games on Windows XP.
Since DirectX 10 was designed to be used on Windows Vista and later, users of earlier systems, such as XP, cannot benefit from the advantages that Microsoft’s API brings to the table. Moreover, the company has no intention of making the package compatible with XP, but workarounds are available.
One of them is Alky's DirectX 10 Compatibility Libraries. This is one of the most popular solutions for XP users who want to develop games and applications using the DirectX 10 SDK.
In other words, these components are able to implement full compatibility between XP and Microsoft’s API; users all over the world are reporting that the package is a success and they can enjoy the perks of DirectX on platforms other than Vista.
Alky's DirectX 10 Compatibility Libraries is addressed exclusively to developers; it consists of a few DLL files that can be deployed following a very strict process. Here’s a summary of the installation process: all of the components should be copied to the C:\Windows\System32 folder, after which you can navigate to DirectX’s SDK folder and run a few examples, just to check out how it works. Detailed explanations are available in the readme file.
In conclusion, Alky's DirectX 10 Compatibility Libraries targets developers and not beginners. Whether used in application or game development, this collection of components mediates excellent compatibility between the DirectX 10 API and XP systems.
