QEMU Windows Guests Glide/OpenGL/Direct3D Acceleration

Witness, experience and share your thoughts on modern CPU/GPU prowess for retro Windows games on Windows 10 and Linux. Most games can be installed and played in pristine condition without the hassle of hunting down unofficial, fan-made patches to make them work on newer version of Windows.

Building QEMU

Following instructions are based on MSYS2/mingw-w64 BASH shell environment on Windows 10. 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-qemu620-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-6.2.0.tar.xz
$ tar xf qemu-6.2.0.tar.xz
$ cd qemu-6.2.0
$ rsync -r ../qemu-0/hw/3dfx ./hw/
$ rsync -r ../qemu-1/hw/mesa ./hw/
$ patch -p0 -i ../00-qemu620-mesa-glide.patch
$ bash ../scripts/sign_commit
$ mkdir ../build && cd ../build
$ ../qemu-6.2.0/configure && make

Building Guest Wrappers

Requirements:

• base-devel (make, sed, xxd)
• pexports, 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

Donation

If this project helps you relive the nostalgic memory of old Windows games, you can now donate to the cause of supporting those games preservation with QEMU. Your donation also motivates and encourages me in research of making QEMU a better platform for retro Windows games.

For $59.99 donation, you will deserve the following donor's privileges:

• QEMU binary package built for platform of your choice (choose one: Windows 10, Ubuntu, etc.)
• QEMU-enhanced OpenGlide host binary package built for platform of your choice (choose one: Windows 10, Ubuntu, etc.)
• QEMU-enhanced WineD3D libraries for Win98/2K/ME/XP VMs for DirectDraw/Direct3D games up to DirectX 9.0c
• OpenGlide guest binary package for Windows
• Elect up to 3 games for priority support and your name as the honorary sponsor in the supported & tested list of games.

A Note to Donation

The purpose of the donation is for preserving retailed CD/DVD games in their originality. It may be used to purchase the game online or from local thrift shops. The donation is NOT the ticket for one to learn how to use QEMU Virtual Machine in general. Sometimes, it may be difficult to get virtualization acceleration working and that would result in serious degradation of game experience with QEMU. It is a willing donation pledge and non-refundable. Many classic Windows games also have re-releases from GOG/Steam that work on modern Windows 10 and Linux. It can be an option to consider before making a donation.

About Game Election

The game election serves the purpose of allocating additional focus and resources to make them work. Sometimes, it means considerable efforts in researching, debugging and tracing the games to root cause the failures and come up with solutions. It is optional to make game election upon donation. My YouTube channel has video demos of games which already worked and more may be showing up periodically. It is typically a safe assumption that games using the same engine (IdTech1/2/3, LithTech, Unreal etc.) would also work, too. The 3 counts of eligibility would only be accounted once the game were made to work. If upgrades were neccessary, it would be a free upgrade for QEMU binary packages.
