DirectDraw to Direct3D9 Conversion

Dd7to9 Introduction

Over the past couple of years I have been working on creating a feature to be able to convert ddraw's DirectDraw/Direct3D to Direct3D 9 (d3d9). The goal of this project is to fix compatibility issues with older games that use ddraw, as well allowing these games to use newer tools that require Direct3D 9 or higher.

The feature is built in dxwrapper and is called Dd7to9. So far most of the DirectDraw APIs have been implemented and, while many of the Direct3D APIs have been implemented, the Direct3D support is still limited.

Note: To view the status of the DirectDraw to Direct3D9 Conversion check out the Status Page.

Installation

To use this feature you can do the following:

1. Download the latest dxwrapper release.
2. Extract ddraw.dll, dxwrapper.dll and dxwrapper.ini files from the release and copy it to the game folder.
3. Open the dxwrapper.ini file and enable the Dd7to9 feature.
4. Disable all application compatibility settings in the application.
5. Start the game and enjoy.

Troubleshooting

If you run into issues try the following things:

• If the movies/videos are not showing up or just displaying as black, try:
  • enabling FullscreenWindowMode. Some older games use a mixture of GDI and ddraw. With Direct3D 9 a surface can only be shared with GDI when using windowed mode.
• If the game crashes after alt+tab, try:
  • enabling the DdrawEmulateSurface. This preserves the surface memory to fix bugs in some older games.
• If the game crashes, try:
  • enabling the DdrawEmulateSurface. This preserves the surface memory to fix bugs in some older games.
  • enabling the SingleProcAffinity. Some games are not properly synchronized to run on multiple CPU cores, or simply don't properly handle powerful CPUs.
  • enabling DdrawDisableDirect3DCaps. Some games will auto-switch to Direct3D and disabling the caps can allow them to use software rendering, which is needed for some games.
  • setting DdrawLimitDisplayModeCount to a value between 32 and 145. Some older games cannot handle a large number of display mode options.
  • enabling the HandleExceptions. This option tries to fix several common exceptions, such as the divide by zero exception in old games that were trying to calculate the CPU speed.
  • running the game with administrator rights. Some older games require admin rights to function properly.
  • making sure you are using the software rendering and not 3D rendering, if the game supports it. Currently this only works with the 2D APIs. Some games only support 3D rendering and won't work with this feature.
• If the game graphics looks messed up, try:
  • setting DdrawOverrideBitMode to a value of 16. Some older games the display mode to be set to 16-bit colors.
  • enabling DdrawDisableDirect3DCaps. Some games will auto-switch to Direct3D and disabling the caps can allow them to use software rendering, which is needed for some games.
• If in-game text is not working, try:
  • enabling FullscreenWindowMode. Some older games use a mixture of GDI and ddraw. With Direct3D 9 a surface can only be shared with GDI when using windowed mode.
• If the game runs too fast, try:
  • setting LimitPerFrameFPS to 29.97 or 59.94 or 119.88 (many other values will work, these are just some common ones).
• If the game runs too slow, try:
  • enabling DdrawAutoFrameSkip.
