WineD3D port for Windows 9x

This is port of Wine 1.7.55 to Windows 95/98/Me. It requires OpenGL 2.1 with BGRA extensions.

Full accelerated package

This is only DirectX wrapper, if you need ready-to-use package for running DirectX, OpenGL or Glide application and games use this: https://github.com/JHRobotics/softgpu

Manual installation (Windows 9x)

Important: some application still need original DDRAW.DLL, don't just overwrite it!

0. Install latest DirectX redistributable (DX8 for Windows 95, DX9 for Windows 98/Me
1. Go to WINDOWS\system folder
2. Copy ddraw.dll to ddsys.dll
3. Edit ddraw.dll in hex editor and replace all (ASCII) "DDRAW.DLL" to "DDSYS.DLL" (this is because system DDRAW register some function for 16-bit applications, if this registration goes to wrong DLL, results are fatal!)
4. Rename d3d8.dll to msd3d8.dll
5. Rename d3d9.dll to msd3d9.dll
6. (only for 98, 95) Copy ddraw_98.dll to this folder and rename to ddraw.dll
7. (only for Me) Copy ddraw_98.dll to this folder and rename to ddrawme.dll
8. Copy d3d8_98.dll to this folder and rename to d3d8.dll
9. Copy d3d9_98.dll to this folder and rename to d3d9.dll
10. Copy wined3d.dll, winedd.dll, wined8.dll, wined9.dll to this folder
11. (only for Me) you cannot overwrite DDRAW.DLL, but is hack for it, add this to registry (ddrawme.reg):

REGEDIT4

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SessionManager\KnownDLLs]
"DDRAW"="ddrawme.dll"

This basically place ddrawme.dll instead ddraw.dll for most applications.

12. Run dxdiag and check result

Windows XP

Although this fork of Wine is mainly designed for use with Windows 9x (95, 98, Me) it is possible to use it with Windows 2k/XP. It is useful when is available OpenGL acceleration but not DirectX acceleration (VirtualBox 6.0) or something in DX support is missing (usually DX6 and DX7: VirtualBox 5.1, VMware Workstation).

Installation on XP

0. Boot to save mode (hold F8 during POST)
1. Go to WINDOW/system32
2. rename ddraw.dll to ddsys.dll (this is important!)
3. Rename d3d8.dll to msd3d8.dll
4. Rename d3d9.dll to msd3d9.dll
5. Copy ddraw_xp.dll to this folder and rename to ddraw.dll
6. Copy d3d8_xp.dll to this folder and rename to d3d8.dll
7. Copy d3d9_xp.dll to this folder and rename to d3d9.dll
8. Copy wined3d.dll, winedd.dll, wined8.dll, wined9.dll to this folder
9. Go to WINDOW/system32/dllcache (folder is hidden)
10. Copy new d3d8.dll, d3d9.dll and ddraw.dll from system32 to here and overwrite files (OR delete these files in this folder). If you don't do it, the system simple recover replaced files back,
11. Reboot to normal mode
12. Run dxdiag and check result

opengl32.dll dependencies

Very important things to known is that in Windows XP system opengl32.dll is calling ddraw.dll so if you only simply replace ddraw.dll with Wine you will get ddraw.dll ↔ opengl32.dll ↔ ddraw.dll ↔ opengl32.dll loop. As solution to this problem special ddraw.dll which is only wrapper to another DLL but it decide based on stack trace which DLL (Wine or system) call.

Look to switcher.c to see how it works

Files

• wined3d.dll - main runtime
• wined8.dll - DX8 interface
• wined9.dll - DX9 interface
• winedd.dll - DirectDraw, DX6, DX7 interface
• ddraw_95.dll - switching library between Wine replacement and system (version 4.8.0.400, for 95)
• ddraw_98.dll- switching library between Wine replacement and system (version 4.9.0.904, for 98/Me)
• ddraw_xp.dll - switching library between Wine replacement and system (version 5.4.0.904, for XP)
• d3d8_95.dll - DX8 switcher between Wine and MS DLL (4.8.0.400, 95)
• d3d8_98.dll - DX8 switcher between Wine and MS DLL (4.9.0.904, 98)
• d3d8_xp.dll - DX8 switcher between Wine and MS DLL (5.4.0.904, XP)
• d3d9_98.dll - DX9 switcher between Wine and MS DLL (4.9.0.904, 98)
• d3d9_xp.dll - DX9 switcher between Wine and MS DLL (5.4.0.904, XP)

(There is no d3d9_95.dll, because DX9 isn't supported on Windows 95, you can use d3d9_98.dll if you want experimenting with DX9 and Win95.)

DLL switcher

Some application are broken when run in Wine (Half-Life for example), bud most of need doesn't require 3D and works with 2D software rendering. To switch individual application from Wine to System DDraw, set under HKLM\Software\DDSwitcher string key with application exe name to system. Example for already mentioned Half-Life:

REGEDIT4

[HKEY_LOCAL_MACHINE\Software\DDSwitcher]
"hl.exe"="system"

It is also possible do it for DX8 and DX9, only difference is registry key which is HKEY_LOCAL_MACHINE\Software\D8Switcher or HKEY_LOCAL_MACHINE\Software\D9Switcher.

Possible values are

• wine = calls go to Wine DLL
• system = calls go to original system DLL
• nine = DX9 calls go to mesa99.dll (Mesa3D Nine driver)
• ninemore = DX8 and DX9 calls go to Mesa Nine driver
• nineforce = same as ninemore but force to use Nine driver even if is not supported
• someother.dll = file name of another wrapper. Can be use as combination with SwiftShader for example.

Compile from source

You need:

• MinGW
• GNU Make
• NASM

Copy config.mk-sample to config.mk, now edit this file and adjust settings. After run make:

make
