in other words, the OpenGLid.ini trick has worked as you said
and all I can say is thanks a lot 😁

A little report after some experimenting with ykhwong cvs build, glide and Tomb Raider 1 & UB, fullscreen and output=overlay.

Tried it using 2 different machines, both with ATI Radeon cards :

#1
is a desktop from 2004, Intel Pentium 4 @3.0 GHz Prescott HT (2 CPUs), 512 MB RAM,
ATI Radeon Sapphire 9600 Pro Atlantis 256 MB VRAM, driver version 6.14.10.6525

#2
a 2006 laptop, Intel Centrino Core Duo T2300 @1.66 GHz (2 CPUs), 1024 MB RAM,
ATI Radeon X1600 256 MB VRAM, driver v. 6.14.10.6587

#1
only problem playing TR1\TRUB with glide emulation, it's real dark, 😎 which can still be fixed fiddling about through the imho too involved ATI control panel settings, then it's fine, smooth and nice to see 😁

#2
here the hordes of Darkness have been defeated, or maybe the boost of RAM counts, anyway there's no need to tune the gamma thing anymore.
As for the cons department, here once out of three or four there's a weird texture corruption, 😵 especially in the new game case after the fmv's are over and the real game should begin, nothing though that won't be fixed either loading a savegame, or starting the dosbox session over again, then it's all gone and the gameplay is good. 😉

Looking forward to trying another laptop equipped with an nVidia GeForce (that's a 5600, I think) card asap to see the difference.

The bottom line is with a little patience in both cases the game is pretty playable and the visual glide effect is good and smooth, much more than I had ever hoped when I decided to try the cvs.

Thanks and kudos to all you developers there.

Well, gamma is controlled by the game itself (using grGammaCorrectionValue), this is then passed to the wrapper which is responsible for setting correct gamma. Openglide (w/ SDL patch) relies on SDL call SDL_SetGammaRamp to set correct gamma value so it's possible SDL messes it up 😁. During testing I found it did not work in some cases, but it worked later after a restart...
As for texture corruption I did not encounter this problem...

so I used another pc I'll call #3 whose specs as follows
a laptop who came into being in late 2003 iirc, Pentium 4 3.06 GHz, 512 MB RAM, nVidia GeForce Go 5600 card with 128 MB VRAM and driver version 6.14.10.4401, and yes, WinXP HE SP2, like the other 2 machines.

On this older computer, TR1 & TR UB are almost as playable as with #1 and #2 from my previous post.
It all goes a little more slowly which sure is no surprise, and a little darker especially so for Unfinished Business, saw no texture havoc so far, direct3d for some highly obscure (to me) reason is my best choice for output settings, opengl crashes dosbox completely, but then this happened with #1 & #2 just as well 🙄 so that's no news

Bottom of bottom line 😎
after these 3 tests, I'd say anyone with a CPU => 3 GHz, 1024 MB RAM and a 256 MB RAM video card should be able to play TR1 & UB without too many troubles.

I still can't get Tomb Raider 1 to run on the DOSBox. The game runs the intro and the movies at the beginning and then crashes. I get an error message "CALL:Descriptor 12 unsupported". The game runs just fine in original mode but not in glide. I did all that was posted in this thread and still I can't make it work. What am I doing wrong?

Update: I made it work but even with Voodoo Rush patch I get the game in original mode not glide.

The glide is activated in dosbox config file.

Make sure glide2x.ovl (the dosbox version) is in the game directory.

Thanks for replying, gulikoza.

Where the glide2x.ovl file would be? I look through all the folders in DosBox downloaded from your and Daum Cafe site and the only glide2x file I found was a DLL file.

Sorry if this sounds like a dumb question but where I suppose to get those files from?

Thanks.

It says on the page:

To enable glide emulation, download an addon 'Glide2x component for glide emulation' in data section.

Maybe I have the wrong version of one or more files needed to make it work? Could someone that has managed to make Tomb Raider 1 working on DosBox in glide mode post the files: glide2x.ovl, glide2x.dll, dosbox.conf and tomb.exe (Voodoo Rush version)? It would be greatly appreciated.

Thank you.

I haven't seen your last post, gulikoza. I'll try that and report back.

Thanks again.

It's working! Thank you for your help, gulikoza!

I still get an error... something about unsupported glide version 135? The game runs fine altough sometimes it freezes for a short period of time.

Will this work on Vista? Has anyone tried it on Vista?

yes

It did not work for me. It may not work if you are using ati card.
(1. glide->direct3d wrapper : invalid glide call..
2. glide->opengl wrapper : no opengl acceleration [due to ati graphic driver problem]?)

[EDIT] tested with vista rtm 6000

Qbix - Could you please post the dosbox.conf file that you use on your Vista? I have a lot of problems on Vista trying to run TR in DosBox.

ykhwong - it runs just fine on XP with ATI card I have. I get an error message: "unsupported glide version 135" but the game itself runs just fine.

> but the game itself runs just fine.

Where's the problem then?

The problem is on Vista. The game runs just fine on XP.

What wd meant was if the game runs fine, what problem are you referring to?

Well, in XP it works just fine. In Vista the game (Tomb Raider 1) starts fine I can watch the FMVs but at the main menu the screen goes black. When I select the new game from the passport (blindly) the intro FMV before the first leve plays and I can watch it but when the level starts the screen goes black again. I can hear the background sounds but there is no picture.

Also at the main menu there is not music just the sounds. Do I need VDMSound with DosBox for music to play?
