Hello, I'got Windows 98 and 3DFX emulation working with Metal Gear Solid 1 in the latest Windows DOSBox-X release. It works but I've got 1 frame per second. :/ I have a CPU which is fine for most games, both recent and no so recent : Intel Pentium CPU G3258 @ 3.20GHz (dual core) And with that a MSI …

Also, if Windows 95/98 could detect and operate the emulated 3DFX card, that would be very very useful ! ;) I don't know how hard it would be to implement, though. Doesn't it do that already? (If the emulated 3DFX card can't be "detected and operated", what good is it?) It works with DOS Glide …

I've also thought of that problem as well where I want to change the CD-ROM or floppy to any arbitrary image I want while running a game or Windows 95. I was thinking of taking the QEMU approach where you can call up a command line window on top of the running game/OS and run some of the builtin …

Hello, Could kekko's work on 3DFX emulation be included in DOSBox-X, pretty please ? (I tried to do it quickly and it failed, seems like it will require at least some work since the patch is for DOSBox SVN) My main motivation behind this is to run early Windows 9X 3D games I can't emulate right now …

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.

Maybe I'm off-topic, but kekko's 3dfx hardware emulation work/patch might interest you : 3dfx voodoo chip emulation (not updated since ages, however...) PS : your plan is a very interesting read ! 😀

Just an update: I just stumbled into the Sound Blaster emulation kludge in DOSBox that prevents the "Crystal Dream" demo's Sound Blaster support from working. See the NOTES in my latest commit, the details are ugly. When I complete more fixes to Sound Blaster emulation DOSBox will finally be able …

Being able to emulate Win9X properly would be great ! 😮 😀 Of course, writing such an emulator is a very difficult task. But the challenge is interesting.

Thanks. 😀 Here is an updated version. (or here for Archlinux users : https://aur.archlinux.org/packages/bin32-dosbox-svn-video ) I hope that it will be part of DOSBox' official code in the future. But for now, I'm just very happy that it works. 😀

Thanks for the leads, I'll try that this evening (in ~8 hours) ! :) It seems that I'm using linux' default governor : powersave . Which means that the CPU changes it's frequency often. Might not be good for DOSBox, indeed ! As for my HDD, it has a lot of free space on a quite recent ext4 partition ( …

Well, bummer. It works alright. But DOSBox pauses a lot, because the thread's queue is often full. And after the first pause, it comes back more often. Although my CPU is at 40% usage at worst. So I've tried : - 30 FPS limit (no more pauses, but it causes a video/audio desync in the output video …

I can confirm now that it works fine with the SVN version.
