Volker Ruppert	5f5d8e2c33	Applied initial version of the 3dfx Voodoo Graphics emulation. The Voodoo core ... is based on a patch originally designed for DOSBox. Currently only the Voodoo1 adapter model can be emulation. The emulation is currently slow, but we intend to clean up and optimize the code. Running the 3D engine in a separate thread is also planned. To compile with Voodoo support the configure option "--enable-voodoo" must be used. Then the device can be activated with "plugin_ctrl: voodoo=1" in bochsrc or on the command line. The device will be assigned automatically to a PCI slot unless you do that manually. A specific bochsrc option to select the adapter model will be added when the code has support for it.	2012-09-14 21:50:50 +00:00
