"HIMEM.SYS allows memory beyond 1MB to become visible as expanded memory if you have a 386 chip. From there you get high memory (the first 64k or so of expanded memory-- but that goes a bit further). If you had an 8088 or 286 processor, you still couldn't directly access the expanded memory. This …

I couldn't help but to advocate DOSBox for games that work exceptionally well with it. TR1 is one of them. The only downside is someone will have to learn to build it until 3Dfx glide pass-through and voodoo1 emulation are upstream into main line code. Once someone get passed that hurdle, the …

Guys, the simple answer is - stop using your retro rigs to play TR1. Get the best CPUs - you can afford, Intel or AMD, even IGP/APU will work and use DOSBox SVN with 3Dfx/Glide support to play TR1.

I don't have a lot of 3Dfx DOS games to test. I only have Tomb Raider 1. And for that, all I need is the official 3Dfx patch which has GLIDE2X.OVL statically linked within the EXE. When you said that they all work under Windows, I presume that you mean the WIN32 version of DOSBox. Most likely, your …

My dosbox build is ~2.8MB out right, and 2.6M after strip. I am not sure how you can end up in such a huge binary. Perhaps, your GNU gcc toolchain setup default to static linkage. I am not into dosbox packaging for distribution. If you build it out from source, then you already have everything. When …

You can get the clean patch of kekko voodoo1 emulation against SVN r3858 here: http://www.vogons.org/viewtopic.php?f=31&t=35814&p=347552#p347552 This gives you 3Dfx chip emulation and able to run both glide and Win9x Direct3D games in Linux.

You have one more option to play the game in DOSBox with voodoo1 emulation and Win98. Base on the year released and system requirements, having DOSBox in modern machines should be suffice to play this game. DOSBox on my not-so-modern Core 2 E8400 3.0G is roughly equivalent to Pentium 266MHz.

The biggest challenge for me was to get DosBox' configure script to recognize that libpng and SDL_Sound were present. I never succeeded at that, instead I had to edit "configure" itself by hand to force their use. I don't know where it expects the header files to be. I just want to say the DOSBox …

It's a 286. If the chipsets does not support EMS, then all 286-based EMS simulator will have the same issues: - EMS page frame located below 640KB, eating 64KB from the precious 640KB conventional memory. - Rely on INT15h AH=87h extended memory block move or XMS memory manager (eg. HIMEM.SYS). This …

Attached voodoo1 patch for SVN r3858. This was something I was looking for but I end up doing it myself. It only contains a clean kekko voodoo1 emulation patch (extracted from TestBuild-3). Somehow, h-a-l-9000's paging patch is no longer required at r3858. Tomb Raider II (DirectX 5) works perfectly …

Actually, I am more inclined towards Direct3D benchmarks to pit DOSBox against real machines in the era of 1995-1999. My main desktop running Win7 32-bit is also an old Core2 E8400@3.0G with GeForce 9400. From most of the past 3D games performance database archives, I think I am getting very close …

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.

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 …
