Hi all!
I'd like to share with you all the latest 3dfx patch with opengl accelerated rendering.
No one worked on it in years, but still, it works quite nice, even if it's not bug-free.

The following options will be available into your config file:

[pci] # voodoo: Enable VOODOO support. # Possible values: false, software, opengl, auto. # voodoomem: Specify VOOD […]
Show full quote

[pci]
# voodoo: Enable VOODOO support.
# Possible values: false, software, opengl, auto.
# voodoomem: Specify VOODOO card memory size.
# 'standard' 4MB card (2MB front buffer + 1x2MB texture unit)
# 'max' 12MB card (4MB front buffer + 2x4MB texture units)
# Possible values: standard, max.

voodoo=auto
voodoomem=standard

- voodoo: use 'opengl' mode for higher speed, 'software' mode for a more accurate emulation
- voodoomem: a standard voodoo1 card usually came with 4mb, but you can max out memory in order to get higher screen/textures resolution

Please find attached:
- a binary file you have to drop into your dosbox installation folder
- a .diff patch against current svn tree (if you don't know what it is, you don't need it)

Just a few recommendations:
- please post all your questions in this thread, don't PM me or anyone else on this and don't open new threads
- if you do anything with this, like adding features or fixing bugs, please share it with everyone by posting your changes on this thread
- if you like this patch, let us know by posting some nice screenshots or videos (please use external image upload service to save vogons.org bandwidth)

Happy Holidays!!!

The following patch fixes some OS X compilation issues but it was never merged in the main patch. Can you add it 😀

Moved to the patches forum. It's high time for an official version of Dosbox with this patch!!!!

Is there a change log for this?
If not, how is this differentiated from the patch in the current DAUM build by Yhkwong? It seems like that has was last updated May 1, 2011.

Thanks a lot ! Really, you're awesome !

I was struggling yesterday on a Windows 8 box trying to get Resident Evil 2 to run without using the ugly software mode. I got the cutscenes to work by installing ffdshow tryouts and enabling it's VFW Intel Indeo 5 decoder, but software mode was in 320x200, really slow, and really ugly. I remember playing it with a 3DFX back in the time in 640x480 fullscreen (16 bpp). The only real solution I found was to use a real Win98 PIII-based PC with a 3DFX, which means I've got to rebulid the damn thing. Again ( 😵 ).

With this patch and DOSBox-X (which, as I understand, is more Win9X friendly than vanilla DOSBox) I might get RE 2 - and other games that even nglide can't get to run because they use DirectX and not Glide - to run properly on a modern computer. At least, there is definitely hope it will be possible someday.

(yes I know I can get the PSX original, or the N64 port, or the Gamecube port running in an emulator today, but I prefer the PC-version-in-hardware-mode's filtered textures).

And that makes a whole lot of DOS Glide games playable now on my Archlinux laptop. That's crazy awesome. 😀
I will definitely try to make an Archlinux AUR script available and maintained.

Ok this is interesting!

I have a noob question, the whole thing with SVN DOSBox always confused me.

Tweaking GOG.com DOSBox games is one of my interests and I had good success with nGlide.

Now will this emulation work with the DOSBox versions that GOG.com packs their games or will I need to replace / upgrade it?

What are the installation steps?

I tried it in one game. I put the Dosbox3dfx into the DOSBox folder, changed the game shortcut to launch Dosbox3dfx instead of Dosbox, edited the existing config file and added the copy paste section from the first post but when running it the DOSBox crashes to the desktop right away.

kind of replace it, instead of using the GOG version you use another one but you need to use the configs from the gog one. There is a how to somewhere, please search and post additional questions in there 😀

I have no good place to put this, but here's a rough port of the new leifx filter shader to the Direct3D patch's shader system. Use with kekko's software Glide rendering for best effect. 😀

tried to turn my 4 pass method into a 1 pass, probably failed doing so. but it does work with the dither sort of. For reference this is my original glsl version

Well. Is any way to force DOSBOX 3dfx to scale Voodoo image? When i set up a scaler for example "hardware3x", the display is scaled but only on 8-bit screens. When i set 16 or 32-bit depth, or when I try to display Voodoo image (for example from X-Wing for Windows 95), I see only a small window. Can someone tell me, what I'm doing wrong?
Here my config:

# This is the configurationfile for DOSBox 0.74-uber. (Please use the latest version of DOSBox)
# Lines starting with a # are commentlines and are ignored by DOSBox.
# They are used to (briefly) document the effect of each option.

[sdl]
# fullscreen: Start dosbox directly in fullscreen. (Press ALT-Enter to go back)
# fulldouble: Use double buffering in fullscreen. It can reduce screen flickering, but it can also result in a slow DOSBox.
# fullresolution: What resolution to use for fullscreen: original or fixed size (e.g. 1024x768).
# Using your monitor's native resolution with aspect=true might give the best results.
# If you end up with small window on a large screen, try an output different from surface.
# windowresolution: Scale the window to this size IF the output device supports hardware scaling.
# (output=surface does not!)
# output: What video system to use for output.
# Possible values: surface, overlay, opengl, openglnb, openglhq, ddraw, direct3d.
# autolock: Mouse will automatically lock, if you click on the screen. (Press CTRL-F10 to unlock)
# sensitivity: Mouse sensitivity.
# waitonerror: Wait before closing the console if dosbox has an error.
# priority: Priority levels for dosbox. Second entry behind the comma is for when dosbox is not focused/minimized.
# pause is only valid for the second entry.
# Possible values: lowest, lower, normal, higher, highest, pause.
# mapperfile: File used to load/save the key/event mappings from. Resetmapper only works with the defaul value.
# pixelshader: Pixelshader program (effect file must be in Shaders subdirectory).
# usescancodes: Avoid usage of symkeys, might not work on all operating systems.

# Cycles can be set in 3 ways:
# 'auto' tries to guess what a game needs.
