QEMU Windows Guests Glide/OpenGL/Direct3D Acceleration

Witness, experience and share your thoughts on modern CPU/GPU prowess for retro Windows games on Apple Silicon macOS, Windows 10/11 and modern Linux. Most games can be installed and played in pristine condition without the hassle of hunting down unofficial, fan-made patches to play them on Windows 10/later or modern Linux/Wine.

Building QEMU

Following instructions are based on MSYS2/mingw-w64 BASH shell environment on Windows 10/11. It is meant to be simple and minor variations are inevitable due to different flavors of Linux distributions.

Simple guide to apply the patch:
(using 00-qemu82x-mesa-glide.patch)

$ mkdir ~/myqemu && cd ~/myqemu
$ git clone https://github.com/kjliew/qemu-3dfx.git
$ cd qemu-3dfx
$ wget https://download.qemu.org/qemu-8.2.3.tar.xz
$ tar xf qemu-8.2.3.tar.xz
$ cd qemu-8.2.3
$ rsync -r ../qemu-0/hw/3dfx ../qemu-1/hw/mesa ./hw/
$ patch -p0 -i ../00-qemu82x-mesa-glide.patch
$ bash ../scripts/sign_commit
$ mkdir ../build && cd ../build
$ ../qemu-8.2.3/configure && make

Building Guest Wrappers

Requirements:

base-devel (make, sed, xxd)
gendef, shasum
mingw32 cross toolchain (binutils, gcc, windres, dlltool) for WIN32 DLL wrappers
Watcom C/C++ 11.0 for DOS32 OVL wrapper
i686-pc-msdosdjgpp cross toolchain (binutils, gcc, dxe3gen) for DJGPP DXE wrappers

$ cd ~/myqemu/qemu-3dfx/wrappers/3dfx
$ mkdir build && cd build
$ bash ../../../scripts/conf_wrapper
$ make && make clean

$ cd ~/myqemu/qemu-3dfx/wrappers/mesa
$ mkdir build && cd build
$ bash ../../../scripts/conf_wrapper
$ make && make clean

Installing Guest Wrappers

For Win9x/ME:

Copy FXMEMMAP.VXD to C:\WINDOWS\SYSTEM
Copy GLIDE.DLL, GLIDE2X.DLL and GLIDE3X.DLL to C:\WINDOWS\SYSTEM
Copy GLIDE2X.OVL to C:\WINDOWS
Copy OPENGL32.DLL to Game Installation folders

For Win2k/XP:

Copy FXPTL.SYS to %SystemRoot%\system32\drivers
Copy GLIDE.DLL, GLIDE2X.DLL and GLIDE3X.DLL to %SystemRoot%\system32
Run INSTDRV.EXE, require Administrator Priviledge
Copy OPENGL32.DLL to Game Installation folders
