Re: [Qemu-devel] QEMU Video Driver for Win NT-based systems

[Natalia Portillo]

This is the same as making a DirectDraw (2D part of DirectX) driver.

A full DirectX package of drivers will be great: DirectDraw (for 2D), Direct3D 
(converting calls to OpenGL in host), DirectSound/DirectSound3D and DirectMusic 
(for the sound card), and DirectInput (keyboards, mice, joysticks)...
