Anyone tried JEMM?

No, but I will. Thanks for the information

Tunnels of Armageddon crashes with the Hercules card after selecting the video mode
Works fine in Dosbox

You mean this? I bet is real behavior... I don't own a real Laser computer to test it though

I only remember Quake with some strange resolutions

So you mean there must be some black borders while you play?

Go with the Diamond Stealth 32, the Mach64 or any standard VGA card that doesn't have 3D features so it won't mess with the Voodoo

What is the most powerful model that retains the PCjr / Tandy mode?

Do you have the MobyGames link for "Ruler of the Seas"? I can't find any info on the Web. Who developed it?

I'm trying to define a new model in model.c but the Intel Southbride PIIX3 is in slot 07h which I think is uncommon. Should I modify one of the lines here? or is it pci.c? void at_brio_init() { at_init(); pci_init(PCI_CONFIG_TYPE_1); pci_slot(0x11); pci_slot(0x12); pci_slot(0x13); pci_slot(0x14); i4...

Anyway, I read both PC87306 and PC87307 datasheets and they look quite different, new registers and different bit values and that's out of my range for programming

Are you sure that this model use an Intel Flash rom ?

No. How can I be sure? And if it doesn't, why do I get that error message?

Thank you for the quick reply Sarah!
I'm currently looking and trying to understand "pc87306.c" - I noticed that all entries with pclog are commented with a double slash. Did you forget to remove those comments? Because they are not compiled and that logging is very useful

Thanks for testing! I found another bug:

When I toggle fullscreen (Ctrl+ALT+Page down) and go back to window mode again, I can't activate the menu in sam and max (F1) anymore. Can you replicate this behaviour, too?

Try using different renders: eg. OpenGL, Direct3D, etc

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
