These interest 3dfx Banshee, Velocity, Voodoo3, Voodoo4 and Voodoo5 owners running
Windows 98SE/me/2000/XP OSes.

At this time 3dfx Voodoo2 adapters are supported in DOS and Linux environments only.
 
MesaFX 0.5.1 is ready 
This new graphics library is OpenGL 1.3 compliant and supports 3dfx Voodoo Banshee,
Velocity 100/200, Voodoo3, Voodoo4, Voodoo5 boards.
MesaFX 5.1 works fine with Amigamerlin drivers series allowing a better execution of
OpenGL 1.3 recent games, like Call of Duty. Besides, running older titles, like
Quake 3 Arena, MOHAA, Serious Sam The Second Encounter, you can get both higher frame rates
and better hardware performance with 32bit of color depth
(this one by cards with VSA-100 chip-sets only). 
 
MesaFX 0.51 installation 
Install procedure is simple and fast, it has these following steps: 
-Unzipping the archive named mesafx_0.51.zip 
-Copying file named glide3x in Windows/System32 folder (MS Windows XP users)  
-Copying file named glide3x in Winnt/System32 folder (MS Windows 2000 users)

What is Mesa? 
Mesa is a 3-D graphics library with an API which is very similar to that of OpenGL.
To the extent that Mesa utilizes the OpenGL command syntax or state machine, it is being
used with authorization from Silicon Graphics, Inc.(SGI). However, the author does not
possess an OpenGL license from SGI, and makes no claim that Mesa is in any way a compatible
replacement for OpenGL or associated with SGI. Those who want a licensed implementation of
OpenGL should contact a licensed vendor. We heartly thank the whole development team made up
of these men: David Bucciarelli, Daryll Strauss, Keith Whitwell, Daniel Borca,
Hiroshi Morii. And of course, Kudos to Brian Paul, sine qua non.
