PCem

I'm trying to add a new computer - IBM 300GL model 6282 - It has the 430VX chipset (already emulated) and the PC87307 Super I/O (only the PC87306 has been coded) I tried to compile the new model using the PC87306 Super I/O but doesn't work. When I try to run the new model the emulator quits - I sear...

In the configuration window I can select 768kB RAM for a Generic Turbo XT.
Question: What happens to the 128kB above 640kB?

Can't it be used by HIMEM like you Philips?

Official pcem is not compiled with MSYS2. it is compiled with the other mingw and not using the exact same versions of the dependencies.
You need to use the dlls that are in msys2.

It works now, I feel so newbie at this

Thanks to the advise of ruben_balea I managed to get the pcem.exe file I renamed pcem.exe to pcem2.exe I moved it to the oficial PCem v15 exe folder The first thing I notieced is the oficial v15 exe is 17 MB large while the new binary I compiled is only 7 MB... When I run the pcem2.exe file I get an...

would it be possible to force higher MHz in the virtual machine?

Sure! An AMD K6-II can go as high as 550 mhz

EDIT: also check if the game has a patch or has been optimized for 3D Now!

Is the game shown there a clone of Lode Runner? How is it called?

Try downloading https://nmap.org/npcap/dist/npcap-sdk-1.03.zip Extract all the contents of 'Include' folder into <msys installation folder>\mingw32\include and all the contents of 'Lib' folder into <msys installation folder>\mingw32\lib Edit: Yes, as jznomoney said there's the proper way to do it f...

I'm compiling as ruben_balea said and works fine, but I get a compilation error at some point - I'm missing pcap.h used in ne2000.c
I believe I'm missing a library
I typed "pacman -Ss libpcap-dev" but didn't work. Any advice?

I'm trying to compile v15 using this guide. Trying to clone PCem directly from bitbucket.org gives me an error, so I copied all the src files to where the clone should be, but when I try to run $ mingw32-make -j it said "No targets specified and no makefile found." So... do I need a makefile? How sh...

[ I recorded behaviour of the game with two other options available: https://www.youtube.com/watch?v=CQd4A4_h6ng Here it works because you're running the game with the Virge card and NOT the Voodoo, and as leilei said, the problem relies on the Voodoo emulation Also, I bet the Virge artifacts are r...

Do you happen to have old hard to test the demo? I wonder what might happen in real hard. Quit to Windows desktop?

The Virge/DX is ok, it really doesn't matter for games as they switch to the Voodoo
As for the FIC mobo make sure you have the BIOS in the correct ROM folder

Try to configure the FIC motherboard with a K6-III @ 400 with a Voodoo2 SLI and 128 or 256 MB RAM
All the games you mention should work OK with the exception of Max Payne that I think needs more powerful hardware

On a Pi3 I can run Doom 2 at 486/25, but most things are happier at 486/16. The A53 is not a fast cpu. Raspberry Pi 4 Released today! https://www.raspberrypi.org/products/raspberry-pi-4-model-b/ Now with an A-72 processor By the way, if I would like to have PCem's executable for Raspbian or the OS ...

PCem benefits from CPU that perform better in single thread, so I believe Intel takes the lead here

orarsis81, On a 386 which PCem emulates, the motherboard which uses the OPTi-495SX chipset, the RAM is actually limited to 32 MB , not 256 MB. The AMI BIOS (dated June 6, 1992) will NOT even recognise more than 64 MB and will not even POST if the RAM is manually set to anything higher than 655,296 ...

Like Sarah said, PCem tries to emulate real behavior of the emulated hardware, but for instance in the 386DX AMI clone you can selected up to 256 MB RAM - that is possible with very uncommon RAM sticks and expansion adapters

I'd love to have cache emulation too, but Sarah said that would cost a lot of CPU host resources
http://pcem-emulator.co.uk/phpBB3/viewt ... 508&p=3436

He made the Plantronics emulation
http://pcem-emulator.co.uk/phpBB3/membe ... ile&u=1312

The ATI chipset you had was this? ATI CW16800-B

PCem doesn't emulate CD copy protection (AFAIK).
Try mounting the image with Alcohol 120% and then in PCem mount that drive (Alcohol unit)

Many thanks for v15.

Given that there is a pattern now, will we expect v16 to be released on June 18, 2020? ... lol

I don't see a pattern here.
v15 demanded much effort and time, but Sarah has not stated there's going to be another mayor task for the next release.

EDIT: Installing gcc-4.9 and editing src/makefile to point to that allowed it to successfully compile and run

What Rasperry Pi model are you using? Can you please tell us what is the best CPU/Mhz PCem can run at 100%?

With the FIC-VA503+ selecting high clock rate for the K6-2 or K6-III result wrongly detected by the BIOS. eg. if you select the K6-2/533 it will display as if it were a 526 mhz - a 500 k6-2 the bios will see it as a 481 mhz

I just downloaded the new version 15. I won't call it a bug, but the zip file doesn't have the folders for the new computers/motherboard's rom

Thank you! v15 finally arrived!
One question Sarah: do you have more ideas for further optimisations?

Nice POST screen! Nice work. I hope it would be added to mainstream

OK i've went through the whole PC-DOS mini image

Slow ones:
D/Generation (66%)
MDK Demo (68%)
Quarantine 2 Road Warrior demo (55%)
Scorched Earth 1.5 (45%)
Ultima Underworld demo (25%)

Do these game work better after rev 1434?

Heck, for even more accuracy, one could go as far as to add support for a hard drive database file to match names, speeds, and dimensions (......and maybe samples) with

I support your idea, in fact I suggested something similar here http://pcem-emulator.co.uk/phpBB3/viewt ... 4855#p4855

Wait and try again with the new version 15
It should be released next month

PS: What game is it?

talbin: the SoD CD-Version is the one distributed by FormGen? https://www.mobygames.com/images/covers ... -media.jpg

leilei: the antology version from iD is this one? Because it doesn't say "anthology" anywhere https://www.mobygames.com/game/dos/wolfenstein-3d__
