either you use dosbox + glide patch by gulikoza
or dgvoodoo
but not both

Thank you it seems you're right, Tomb Raider works with OpenGlide, I only tried it with dgVoodoo dll because in carmageddon's case openglide doesn't work. But the game still stucs at the manu when I try to load or start a new game.

you might as well try this setup I made
http://www.tombraiderhub.com/faq/tr1.html#advancedsol
(search for dosbox solution)

Looks interesting, but could you tell me essentially how to tweak gulikoza's pre compilled dobox config to run Unfinished business in 3Dfx mode? I couldn't engage the game because the game allwasy stucks in the main menu. I set direct3d to graphics, opengl doesn't work because of a dosbox crash

well you extract the glide patch + dxd9 files (overwriting)
then install trub being sure to make it via 3dfx (not software) pack
then set glide=true, output=direct3d
that's about all there's to it, I guess

gulikoza's pre compilled CVS already has the glide and a dozen more patches, I have that directX 9 stuff installed, I set direct3d and also have the 3Dfx version installed, yet it stuck at the main menu after I want to start a new game. I don't know what else to do... 😵

did you follow those instructions to the letter ?
If not, do so.

Yes I think yo, so here is what am I doing,

I. I downloaded gulikoza's CVS with the glide patch in it (I already installed d3dx9_30.dll)

II. Writen a new dosbox config file, added a bit more memory for 3Dfx apps (31) set output to direct3d, enabled glide disabled printer and enabled GUS, also automounted the Tomb Raider CD

III. I've installed Tomb Raider insde dosbox set soundcard to gravis ultrasound, replaced tob.exe with the "VOORUSH" 3Dfx patch.

IV. The game runs good in 3Dfx mode at first start, I've backuped and installed the 3Dfx version of Unfinished business.

V. Start the game from the TOMBUB.EXE nice 3Dfx logo and then the menu and music too. I select New Game and ENTER. The music is still there but the program is frozen, no error on console but the game does not start.

i don't see any mention that you need to enable the gus

Unbeliveable you guys GUS was the cause of all my problems with the game, this have been a good lesson for me nonetheless. By the way in DBTR4 there is a TOMB3Dfx.EXE is seems to do exactly the same as the Eidos patch, what is the difference between the two?

that's not so unbelievable 😉
I guess you were putting too much into .conf
like set soundcard to gravis ultrasound, what's the need for it? soundblaster's just alright

as for that 3dfx exe, I know, no difference that I recall 😀
I just put it there to ease the setup work for the user, to get things preconfigured, you know

Now that I disabled GUS Tomb Raider runs great but sometimes the game still freze at the menu, but at least something appears at the dosbox console: "8 bit irq pending" this appears on the console in infinite mode 'till I turn it off. I autodeceted the Sound Blaster 16 card in setup.exe, it is the second best card after Gravis Ultrasound, but still this one isn't perfect too. Is there any solution for this? Or a sound system patch that fixes this?

no, I always went sb16 since 0.6x

like:

sbtype=sb16 sbbase=220 irq=7 dma=1 hdma=5 […]
Show full quote

sbtype=sb16
sbbase=220
irq=7
dma=1
hdma=5

in the .conf

that's a bit strange, since I guess it always autodetected as soundblaster 16

admittedly I didn't test 0.73 that intensively yet, but by what I saw so far, no special freezes.

This is exaclty what happens:

I have no idea wht this means but it would be nice if it could be fixed, Tomb Raider works but about every second start off the game is good, a rest will freez in the menu with this 8 bit pending thing.

I also upload the conf file to for re checking, and I even refreshd the DOS4GW to the latest 2.01.

first of all
don't

# Lines in this section will be run at startup.
mount C C

mount c c:\[some_directory_of your choice]
but not c:
that's no good practice and it can be dangerous indeed.

EDIT
as for the 8bit irq pending issue
see this thread
Topic 21976

btw you happen to use a cue/bin image don't you
does cdaudio work alright?

C is not my root "C:\" drive it is a folder in the dosbox root directory.

huh? what's that?
I'm afraid this is lost on me
now what's the path of the folder you say?
c:\<insert here>

EDIT
anyway why not try the zipped setup I made
that was made w/0.72 and shouldn't give any irq pending msg afaict

There is a folder named "C" in the same directory where dosbox.exe is that is why I use this: "mount C C" this will set the C folder as the virtual C:\. As for the error Ifount this: ArchimedeanDynasty crashes since CVS-Build 2009-06-14 it seems that this error was not present in the 0.72 version so that can be the reason why you haven't came up with this.

The irq pending issue might be the result of some patch in my build. This was actually done by dosbox authors but sometimes I have the feeling it occurs more frequently in my build then plain cvs...I will try to get it fixed in the next build. I found out the menu does not freeze if the cycles are set to let's say 75K...
