Re: Direct3D games in DosBox

Hi Truth, Can you share some benchmark numbers with the build on Voodoo1 emulation? - PCP Direct3D benchmark - 3Dfx Wizmark - Quake 2 timedemo - Final Reality 1.01 - 3DMark99MAX. I can't get this to run fully, but the results from the 2 game demos should be good.

Re: Glide 2.1.1 games and Voodoo 2

in Windows
Have you tried dgVoodoo? It supports GLIDE 2.1.1 and works with most DX7 class hardware. SST1INIT.DLL/GLIDE.DLL are not meant for anything other than Voodoo1. There are list of 3Dfx env vars for a Voodoo2 to emulate Voodoo1 floating around in the web which you can google it by yourself. If this …

Re: Glide patch

I noticed issue on LFB accesses causing flicking. This only happens with dgVoodoo, but not OpenGLide. For example, when pulling down console in Quake II demo, the console text is flicking. Similar, for games which render HUD using LFB, the HUD is also flickering. This is observed in MechWarrior 2 …

Re: DOSBox-X branch

Another good solution to avoid pf_queue overrun is to avoid using S3 display drivers. Use VBEMP VESA generic driver. Here's the behavior of S3 drivers on Win95 and Win98SE which I can conclude: - Win95B/C (OSR2/OSR2.5) In-box S3 drivers is completely unusable. DOSBox will crash with pf_queue overrun …

Re: DOSBox-X branch

Hi, I think DOSBox page fault handling deserves its exclusive discussion. See http://www.vogons.org/viewtopic.php?f=32&t=37417. My solution to this is to enable pf_queue monitoring and keep restarting DOSBox until it reaches Win9x desktop with pf_queue fully flushed. As a side note, optimized build …

Re: Glide patch

I haven't tried out the voodoo chip emulation in DOSBox. I read the post and I feel that it may be too slow as not everything is accelerated with host OpenGL and I couldn't download the patch from the thread. Don't get me wrong, I don't mean to despise its significance, but I think Glide pass- …

Re: Glide patch

Gulikoza, by the way, do you have any interest to port your glide pass-through patch to QEMU? This would definitely breath new life into retro gaming for early Win9x native 3Dfx glide games.

Re: Glide patch

I found an issue with Glide patch. When DOSBox is using imgmount'ed disk image instead of the mount'ed local folder, Glide calls which deals with local texture file, such as gu3dfGetInfo() failed located the file in the guest environment to feed to the host glide wrapper. I had a workaround to put …

Re: Glide patch

Yes, I did have the correct glide2x.dll in the guest OS. Nevermind, I figured it out. Somehow, the MapPhysToLin() implementation using VxDCall to DPMI service in Win9x was failing. I don't know why. I applied h-a-l-9000 paging patch, updated S3 drivers and somehow things were working. I am able to …

Re: Glide patch

It works with Tomb Raider from DOSBox or booted Win95 MS-DOS prompt in DOSBox. This is the only DOS Glide game that I can check. However, none of the WIN32 Glide apps/games work from within Win95. I tried Glide demos/tests from 3Dfx SDK and NFS2SE demo. All of them end up in protection fault within …

Re: Building with gcc 4.7.0, SDL-1.2.15 and SDL_net-1.2.8 produces exe that crashes with Exit to error Illegal GRP4 call 5

See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52991 Yes, -mms-bitfields is only turned on by default for Windows mingw targets. However, this exposes a bug since gcc 4.2.0 that __attribute__(packed) is broken with -mms-bitfields. I can't understand what state of mind GCC dev team is in when it is …

Re: Building with gcc 4.7.0, SDL-1.2.15 and SDL_net-1.2.8 produces exe that crashes with Exit to error Illegal GRP4 call 5

Solved. The problem was caused by gcc 4.7.0 and above turning ON -mms-bitfields by default, but in dosbox source files the #pragma pack(1) is only applicable to MSVC. So to build dosbox SVN without changing any of the source files, it needs to be configure with CXXFLAGS="-mno-ms-bitfield .... " With …

Re: Building with gcc 4.7.0, SDL-1.2.15 and SDL_net-1.2.8 produces exe that crashes with Exit to error Illegal GRP4 call 5

I am wondering if building DOSBox with gcc 4.7.3 or gcc 4.8.1 under Linux/x86 (not x64) is producing a working native binary. I don't have any Linux distro with such recent GNU tool chain available at my disposal to try this out, as my primary machine is still Win7. And, I am not in a mood to build …

Re: Building with gcc 4.7.0, SDL-1.2.15 and SDL_net-1.2.8 produces exe that crashes with Exit to error Illegal GRP4 call 5

I had built SDL, SDL_net and SDL_sound with MinGW and I had no issue with the builds. I am not sure about OHQ addition into SDL. Does OHQ mean OpenGL HQ? My SDL does not have such enhancement. It is frustrating and discouraging to see open-sourced projects leaning towards propriety tool chain, …

Re: Building with gcc 4.7.0, SDL-1.2.15 and SDL_net-1.2.8 produces exe that crashes with Exit to error Illegal GRP4 call 5

Bring the thread back into dev attention. Is there a plan to understand the problem with compiling with MinGW gcc > 4.6.2? Both gcc 4.7.2 and 4.8.1 have been released for MinGW/MSYS and I had tried both and they both produce non-functional DOSBox binary. I have been building DOSBox from source since …

Re: MechWarrior 2 | 3D card conversion files

The only version that is worth archiving is the 3Dfx version. Thanks to glide wrapper, dgVoodoo especially, and several patching methods available to run the game in WinXP/Vista/Win7, the game runs flawlessly on state-of-the-art CPU/GPU as of today. Imagine the absolute fluidness during intense mech …
