This is a list of XDK, Xbox hardware, and Xbox operating system specific limitations. XDK and Xbox specific software limitations The Xbox has four non-standard USB ports but the Xbox SDK does not contain a full USB stack, thus to add support for USB hardware devices, the developer would have to code the entire USB stack from scratch.Xbox hard drive file system (FATX) has many limitations, among them a maximum file name length of 42 characters.Only a single process ( executable program) can run at a time on the Xbox.Everything else must go into the main executable and its (XDK and own-made) libraries.The Xbox does not have an operating system per se, instead it only has a simple BIOS.Also required to compile (and program in) is Microsoft Visual Studio. The Xbox Software Development Kit (SDK) (with libraries) is required to compile video games and applications for the Xbox.Compiling games and applications for the Xbox Because of the constraints on the hardware and environment of the Xbox, all software development for the Xbox (and all video game consoles systems in general) are focused on reserving the limited resources that exist, the main limitation of which is the amount of available RAM. The Xbox BIOS is based on the NT 5.0 kernel, but does not have all of the resources or capabilities of the Windows 2000 operating system, (for example: neither DirectShow, registry, or DLL are natively supported on the Xbox). Bundled with XDKs is the Xbox 360 SDK used to connect to the console, enable memory editing, file management, and integrate to Visual Studio 2010 for Xbox 360 game development.

Some, but not all, XDKs include a sidecar which was used to emulate the DVD drive and act as a hard drive and on older XDKs with older recoveries, used for PIX Debugging. XNA Kits (Were used at some expos and given to game studios), Stress Kits (Used to test the power of the Xbox 360 and various conditions such as undervolting and overvolting and issued to Microsoft developers only), and Demo kits (Used to demo games). Xbox 360 XDKs were based on all three generations of the Xbox 360 Design ('Phat', 'Slim' and 'E'). The XDK allows software creators to create, run and distribute applications on the Xbox platform.
