Updated 1st post. OpenGlide fork optimized for QEMU is now available . This is mostly meant for Linux folks, especially ARM SBC/RPi4 community where 1st-party Glide pass-through can be faster than 3rd-party Glide from Windows guest on top of MESAGL pass-through. For Linux x86/x64 with KVM, no big …

Geforce 6 lines do not have Win9x driver support . I go by official source. Otherwise, I would have kept my Nforce 630i/GeForce 7150 IGP motherboard for old Windows games with Core 2. If you want to hack the drivers, then it is your choice. I stand corrected. Edit: Actually Geforce 6 lines do have …

I gave you notice before and for good reason. Would you like it if someone else mentioned constantly their perceived issues with Qemu ad nauseum? You want to play games at ridiculous high fps in Windows 98 in Qemu. That's fine. We get it. Qemu is the greatest piece of software in existence. Someone …

how much better the performance could be if a proper QXL driver were written for the Win9x family of operating systems. In my opinion, not much. Both VBEMP and QXL already use the same Bochs dispi as VESA backend. VESA/AF had failed and no one bothered with it. There isn't an easy way to map 2D …

"This ain't fair, you should compare PCem with QEMU TCG!" Great idea, let's do that and compare device emulation vs API pass-through :b Let's give PCem some head-start, 16bpp is OK, max resolution at 800x600 and penalize MESAGL with 1024x768 32bpp. This is, again, **unfair** (depends on how one …

VBEMP is good enough, though it is free only for personal, home & non-commercial use. It does not endorse FSF open source philosophy. QEMU's answer to this is QXL, but unfortunately only WinXP and onwards. QEMU uses Bochs dispi as the VESA backend which is *host accelerated* for hardware …

There is still at least one remaining problem with kvm and VBEMP drivers: Qemu hangs on shutdown (must be forced to close). I think this was mentioned before (but no workaround). Not a major issue though. Very good observation :thumbup: ! I had lived with this for many years without solution ( ... …

VBEMP Win9x does not support windowed DOS prompt on Win98/ME, VBEMP NT does on Win2K/XP. If you need to run DOS programs or DOS BATCH scripts by clicking on the files from Windows Explorer, then do this . Or just run them from a fullscreen MS-DOS prompt. It is a well-known limitation, even on real …

Mobile vs Desktop class CPU, the Desktop class has higher base & turbo clock and can sustain longer turbo boost due to higher TDP budget. PCem likes that, but I won't budge the fact that PCem CPU re-compiler could also be more optimized for Linux. I have measured QEMU TCG up to 30% faster on …

I think all pci soundcard that provide soundblaster emulation require the use of having the cpu in virtual 8086 mode. No, not all PCI soundcard. Some have built-in port trapping and DMA snooping logic and do not rely on CPU virtual 8086 mode to do so. From a technical perspective, this works for …

The last of Celeron 433MHz PC-9801 was based on Intel 440FX chipsets, too. I guess this is what you have. So the Voodoo2 driver INF didn't complain and proceed with driver installation? Which flavors of Voodoo2 do you have?

You can still try the Win98 driver for Voodoo2, if it does not do any harm and you have backup ready in case of the need to restore the OS. Since Voodoo2 is just a non-VGA standard PCI device, it doesn't need IRQ and DMA and the rest of the PCI is typically architecture agnostic. If the Voodoo2 …

If it can run Win98, then the Win98 driver for Voodoo2 should just work. I assume it runs the typical Win98, not a special version of Win98 created just for its architecture. The Japanese market used to stuffs with lots of its own standards. The OS driver model typically provides the abstraction to …

Oh sure, that is when one's expectation was realistic. I am pretty sure Moto Racer 1 (1997) works nicely on your gaming laptop, too, but I play the same game on 9 years old AMD C-60 Acer netbook at 30FPS and Celeron 847 ASUS netbook at near 50FPS with QEMU KVM on ArchLinux. 🤣
