Try the guide on PCGamingWiki:

- Install the game.
- Go to the game folder \Bin (where the Blade.exe is) and delete all glide files: glide.dll, glide2x.dll, glide3x.dll and nglide_config.exe.
- Download dgVoodoo2. After unpacking it, copy dgVoodooCpl.exe and dgVoodoo.conf to the Bin folder.
- Copy the four files from dgVoodoo2\MS\x86 (D3D8.dll, D3D9.dll, D3DImm.dll and DDraw.dll) to the Bin folder as well. Override if prompted.
- Execute dgVoodooCpl.exe in the Bin folder. This opens the dgVoodoo menu. Here, you can set your custom settings for the game. Click on the symbol on the top right (.\) to set this location as running instance.
- In the dgVoodoo menu, set the following:
General tab: Appearance: Full Screen; Scaling Mode: Stretched, 4:3 Aspect Ratio
DirectX tab: VRAM = 2048 MB. Under Miscellaneous, uncheck everything except Force vSync.
- Go to \Data and rename, move or delete the folder video.
- Now you can launch the game from the Blade.exe (under Bin). If it has problems, run it in Compatibility Mode for Windows Vista (no Service Pack).
- In the launch menu, select Setup. Under Video, select D3d. Click Configure. Here, you can set a resolution. The highest supported one is 2048x1536 at 32 bpp, which is 4:3 (widescreen / 16:9 is stretched and thus not recommended). Click on Full Screen and select Max details. Confirm everything.
Now you can play the game.
