[feature-request] Voodoo 3DFX emulation

Reported by: Zombiedeth Owned by:

Host type: other

Description

Add Voodoo 3DFX emulation for legacy gaming and other uses in DOS and Windows 9x. The emulation already exits in MAME and is being ported to DOSBox. I feel this would be a good addition to VirtualBox and probably simpler than some other ideas proposed for legacy gaming.

Interesting, but not easy to do.

Also it may be easier to develop decent Video drivers for "VirtualBox Graphics Adapter" for Windows 98 guest, than to provide 3DFX emulation.

  • Priority changed from major to minor

Sorry, but there is no business case for such a major undertaking. This is best done by the open-source community. I'll leave it open only for that.

Replying to Technologov:

-Technologov

I can't say for sure which one is easier but AFAIK VirtualBox has to use wined3d and that doesn't support Direct3D v6 or v7. That would limit a fair number of classic 3d games.

I honestly think 3DFX emulation would provide better compatibility you get D3D v6, v7 and glide.

VirtualBox has to use wined3d

Nope. VirtualBox doesn't "has to use". It just uses now, but development of good drivers is theoretically possible, instead of WineD3D.

Theoretical techniques could take years to get something usable. The 3DFX emulator in MAME has been in stable use for years. And the port to DOSBox took about a month at most to get something usable.

While a "VirtualBox Graphics Adapter" for win9x would be ideal lets be realistic it's not going to happen any time soon if ever.
