Red Orb Prince of Persia 3D 1999 At young age, I enjoyed the first 2 games very much. When the 3rd game was released with hardware accelerated 3D engine, I had high anticipation but it played like shit on Voodoo1/2 at 640x480 without high-end CPUs back then. Reviews of the game were largely …

You're probably the first person to get QEMU compiled but didn't know where to proceed. I would have thought compiling QEMU from source would be the most difficult hurdle to get through. Once it was done, everything should be simple. Anyway, you will need Glide Wrappers for 3Dfx/Glide. It is obvious …

I recently thought of another idea though, if I can get an Direct3D to OpenGL wrapper working with MesaFX, then what if I just don't use Windows 98 in the first place and go to XP? Of course, I see problems here already, one of them is that I probably won't be able to get this working this way at …

Yes, Half-Life 2 does work on Win98SE VM on QEMU, even on DX9 renderer code path, thanks to WineD3D. I checked it, version 1.0.1.0 Source Engine 6 (build 2187).

The fundamental question for the OP is : What is your objective ?

Well, I bet crazy ideas are everywhere nowadays :b, …

VSA100 drivers are capable to force 32-bit color in Glide, just like wrappers or emulators. No Glide games can actually use this. The official Glide specification 2.x and 3.x released had never included support for 32-bit color and high-resolution texture. They can only be used by 3Dfx OpenGL 1.1 …

There are a handful of DOS Glide tests from 3Dfx Glide 2.43 SDK that cover simple triangles, texturing and LFB operation, but none of those are game-like tech demos. For game-like tech demos, my favorites are "Valley of Ra" and "Race" from 3Dfx archives. They only run on Windows though.

I looked at why Unreal1 226f OpenGLDrv crashed. It suffers 2 very common programming errors at the time, buffer overflows due to huge number of pixel formats returned by WIN32 API and large number of GL extensions from glGetString(). Since QEMU MESAGL on Linux has to emulate Windows OpenGL behavior …

QEMU MESAGL had the solution for this exact problem for Half-Life 1. Apparently the game maintained 2 window DCs, one for the UI/menu and another for OpenGL context. It (or Windows OS) did issue WM_ACTIVATE messages switching between UI/menu and in-game screen. The OpenGL ICD should have captured …

I think the "-window" is always required. Use "-width" on the command line to select the desired resolution. GLQuake 0.97 displays such instructions when you go to "Options->Video Options". You can also use "-height" to have the game stretched to different aspect ratio or just omitting that to let …
