PC emulation is quite demanding. You could try a Pentium 60 or 66 (Socket 4), or maybe a P 75.

If it still drops below 100%, you could try something like Dosbox-X, although installing windows in that is not as straightforward. You could also try a virtualizor like VMware or Virtualbox.

Hm, a volume control option in the PCem UI for OPL emulator would really help.

Didn't realize it controls both. Really a bad design on creative's part to combine them, since I'd constantly have to adjust the volume when switching between MIDI and FM.

I haven't seen a specific FM volume slider with Sound Blaster tools. Maybe I'm using the wrong one. Can you post a screenshot? As for adlib, it doesn't have a tool. IINM on a real card there is a physical volume knob on the card itself. PCem's sound menu is of no use to me since it affects all sounds.

On my setups, FM synth volume is very low, compared to digital and MIDI. I haven't tested all cards, but it's the case with adlib and Sound Blaster cards. There doesn't seem to be a volume control for it.

Has anyone experienced this?

Also intrigued by your suggestion about mounting the CD in the host system. For some reason when I do so (either with the native Windows 10 iso mounting capability or with Daemon tools) I don't see an option in PCem to access the virtual CD drive (see screenshot below), and the image is definitely ...

1. Do not use ISO format for CD images. Some CD-check based protections scan the structure of the CD, which ISO doesn't provide. Use the BIN/CUE format. Also, with ISO, you will not have game music if the game's CD has audio tracks, which X-Wing vs. TIE Fighter does. By the way, when loading the ima...

Which games? Have you checked to make sure they are running on the voodoo and not virge?

As harrison pointed out, you'd have to check where the mismatch is happening. There are three places: 1. The refresh rate set by the game itself. Some games force a specific value or allow it to be set to a specific one. 2. The refresh rate of the emulated monitor set in the monitor settings. You ca...

Whatever FDD you select in PCem, make sure it's set to the same in the BIOS too.

Are you using DOS? Maybe try windows 9x.

Any reason you're using v16 and not v17? The sound is stuttering because the emulation speed is dropping below 100%, because that ryzen's single core performance isn't high enough to handle a pentium 233 (EDIT: in that particular situation). It has nothing to do with instructions or CPU brand. Searc...

OEM images don't need a floppy, and can be booted with the boot sequence set to CDROM.

There are many guides online showing how to install windows 98. It's not a PCem matter.

It's not a PCem issue. Only OEM windows 98 CDs are directly bootable and don't need a floppy. For any other type, a 98 floppy boot disk is also required. The boot sequence for the latter should start with drive A; the rest don't matter. If it still doesn't work, go to the D: drive (might be E:, with...

The highest end hardware that PCem emulates are Pentium 2 and Voodoo3, so 2002 and newer games won't have good performance, some will have graphical issues, and some will not work at all. I do not recommend it. (Many 2000-2001 games would also struggle on a P2 though) The majority of games that were...

Your post didn't make it clear that windows itself didn't have working audio. I thought only the games were lacking audio. No, PCem works mostly ok with windows 2000 and XP, however for games released in 2001 and earlier, there's no point in using anything above 98 SE. Windows 2000 and XP are NT bas...

Both games that came out around the XP era, but also before. I am from 1995, so that might give you an idea. Tried that soundcard too, still no sound. Configured a Win2000 instead. Same issue, same soundcard. Might just tweak the games to Win11. Just wanted the optimal feeling of the games. And nos...

Which lego games, exactly? If these were released after XP came out and are compatible with it, you should be able to make them work on windows 11 itself with minimal tweaking, without using PCem. If they are pre-XP games, use Windows 98 SE instead. There is no need to use an AWE32; that card's EMU8...

There is no compatibility issue between those cards. You simply have to set the IRQs correctly so that two devices don't share the same one.

You also didn't mention which boards you selected, so it's not much help.

Regular VM software have guest additions that enable that feature, e.g. VMWare Tools. PCem doesn't have such tools.

I suppose one workaround is to use networking. Connect the host and PCem guest through a network and share a text file between the two.

I tried the shift right click but you can't move the window unless you click on the window title bar. This is with Win10. After you select "Move" from the menu, don't click again or press any other buttons. Just move the window with the arrow keys and then press enter. My window is set to...

You either get them by dumping from the hardware itself, download them in the form of "BIOS updates" from the manufacturers' websites, or from other sites that host them.

It's a known issue and has been fixed in the vNext builds.

Unfortunately vNext is quite slower than v17, so I can't switch yet.

You don't have to keep each image file in its own folder (don't put them in the PCem root though); just give them names that can make identifying them easy and put them in a folder named HDD or something. Examples: 1A-win98se-p55t2p4-voodoo2.img 1B-win95osr2-hot557.vhd ... Also, unless you need them...

I've never had this issue. I mostly use ASUS P55T2P4 and Shuttle HOT-557. Which system/board are you emulating? I'm not sure if this is related, but are you storing PCem or the HDD images in a location that requires admin access, like "C:\Program files", etc? When creating images, don't ty...

PCem itself obviously supports ISO files, considering you managed to install windows XP. If you mean they don't show up on the guest XP, then as Arjen42 mentioned, they are probably of a format that is not supported by XP. I use CDBurnerXP to make them. P.S. I should note that there seems to be a sl...

What about running CPU stress tests in the guest system (like Prime95 or one of the CPU tools from https://www.ultimatebootcd.com/) This would max out the guest CPU, so you can at check in parallel on the host CPU if it can handle the guest CPU's load, right? The emulated CPU does not behave like r...

You don't create roms from scratch. You find compatible rom files online, which were dumped from the original hardware or acquired from manufacturers' websites (bios files), and put them in PCem's roms folder.

Your current CPU probably can handle a Pentium 133, but the only way to make sure is to test it yourself. While running PCem, check "CPU time" in the Machine window. When it goes past 100%, the emulation speed will drop. Pentium Overdrive isn't really different from a regular one. What mat...

I haven't really noticed a difference. Maybe it's CPU model and/or OS dependent. banshee... one thread for the cpu and two for the voodoo. Have you set it to 1 render thread then? Video cards have a +1 thread count. A banshee with the default 2 render threads spawns 3 threads. The total PCem thread ...

I wonder if the new 13th gen intel core i7/i9 laptop CPUs will fix many if not all of these slowdown issues? Obviously it depends on which program or game you are trying to run, but in my experience it is a question of having a fast enough PC to run PCem without these slowdown issues. Using the sam...
