PCem

Zup: In PCem window click in the option menu Misc->Machine, and in the Machine window select Speed history. The 100% mark corresponds to the second line from top in the graph. Start a machine with a Pentium CPU and check in the graph which is the fastest emulated CPU that never goes below 100%. In m...

This project is a hobby, not a work.

It's an open source project as well. If someone wants to add something it is possible to download the source and modify it.

It is possible to include the fastest virtual CPU that is possible to emulate with the physical one? Or include a FAQ or pin a post with this information.

Mine is i5-3210M (2 cores / 4 threads at 2.5 GHz) and I am able to emulate up to Pentium@75 at almost full speed.

Have someone experienced this issue or depends on a very specific configuration?
Could be fixed for v14?

Great!
Thanks Sarah

CALL should only work witch batch files, but as a test try:
call C:\MSFS5.1\fs5.com x

Could be a problem of QEMM?
Have you tried memmaker?

Visual Player 2.0 was a MOD (Amiga module) player for DOS. Sound Blaster 16 support is broken (no sound is output). In DOSBox this issue was corrected in commit r3850 but no new stable version has been released since. Changes in DOSBox code can be seen here . Is possible to port this code into PCem?

Every time I open the VM, the main window appears below the last position with the increase of some pixels. The machine window always opens in the same previous position. If I don't move the window and keep opening and closing the program, the window goes off screen. I am using Windows 7 x64 with a ...

I have noticed that time synchronize depends on the emulation speed. With a Pentium 75 (which I emulate at 100%) I get a 2-3 seconds delay from host, but with no increase. With a Pentium 200 (62% emulation speed) I get a 10 seconds delay increase every minute. Is this the expected behavior? I have t...

If I activate the "Remember size & position" option the machine dialog always appears in the same position, but the main window appears a few pixels below in the y axis from the last position. Every time I start a VM I have to move the window. I haven't seen any other message about this, so, is ther...

I don't think it does. You're probably creating an image over some fragments. For me, it didn't take 2 minutes to make a 40gb today. what takes longer though is moving all those smaller images into the bigger ones since there's no real easy img-based tools to do so and WinImage drag-and-drop isn't ...

Does the last commit speed up the creation of hard disk?

In PCem 10, in a 5400 rpm hdd, create a 2 GB disc takes 30 seconds, while in PCem v13 (since v11 i think) takes 2 minutes.

PCem v10 seems to create a new hard disc much faster than newer versions.

In a 5400 rpm hdd, create a 2 GB disc takes 30 seconds, while in PCem v13 (since v11 i think) takes 2 minutes.

Is there any reason for this change?

Thanks Sarah (and others) for this great emulator!

Lots of nice changes and additions from v12

On Pcem 12, Destruction Derby (Diamond 3D / S3 Virge, Windows 95) using 512x384 resolution results in a vertically stretched image.
Terminal Velocity with S3 patch: missing hud and textures.
I don't know if this still happens in 13 WIP.

I didn't know that has already been answered.
Thanks omarsis81

Hi and thanks for this great emulator. I've been using it since v9.
I noticed in Award SiS 496/497 that any CPU at 16 or 33 Mhz fails to boot with recompiler enabled.
